Installation Standards

Controlled Unclassified Information 1 of 32

1.1.1. As a general rule, the JBER Telecommunications Installation Standards will be used as the primary design and installation guideline for the unclassified (Niprnet, Voice, etc.) cable plant material and installation efforts. Although some information is included in this document as general reference information regarding various classified communication systems, it is listed here for convenience and general awareness only. There are specific standards that apply to these specialized, classified systems that shall be referenced as part of their design and installation process to ensure that those systems are fully functional and can be accredited as an operational system by the appropriate certifying agencies. In case of a discrepancy between various standards and guidelines, the most beneficial to the system being installed shall apply (greatest separation from electrical noise sources, largest bend radius, lowest pulling tension, largest communications room size, largest expansion capability, highest drop count in an area, etc) to afford the greatest protection and security to the cable installation and improved life cycle capability of the installed infrastructure. Any specific exceptions must be agreed to by the 673rd Communication Squadron Plans Shop (673CS/SCXP), in writing, on a case by case basis. To be considered as part of the deliverables for any project will be a complete equipment labeling effort and as-built documentation package relevant to the communications systems (take into account specific guidelines shared throughout this installation standards document).

This will include such items as, but is not limited to, labeling of cables in duct systems, labeling of cable termination points, drawings showing as-built floor plans and rack elevations, and in general, the labeling and documentation of any work done to support the efficient maintenance and usage of the newly renovated or newly installed communications material, such as equipment racks, cables, cable routing diagrams, communications relevant floor plans, cable count break outs for splice plans, geobase survey information for outside cable plant work, etc. All labeling schemes will be routed through 673CS Project Managers for written approval, prior to implementation. The labeling scheme submitted for approval will include a floor plan showing the locations of each relevant label (i.e., the location of a comm. equipment room with room number, the location of each faceplate with its discrete label, comm. room layouts with equipment/rack labels shown per each equipment location, etc.). The labeling scheme and associated documents will be delivered for review no later than the 95% design review timeframe.

1.1.2. Information provided by 673CS will generally be provided in an Adobe Acrobat (PDF) format. Any editable drawings provided by 673CS will be in Bentley Microstation V8 ( *.dgn format); editable documents will be provided in Microsoft Word or Excel format. As-built drawings provided by the contractor for telecommunications installations will be Bentley Microstation V8 format. Drawings returned from the contractor will be provided in a fully open, unlocked, exploded format with all associated reference drawings/layers so that all details contained within the drawing can be individually edited using Bentley Microstation by Air Force personnel at a later date.

Any outside cable plant drawings (butterfly drawings, plant in place drawings, etc.) or site layout type drawings will be provided in an Adobe Acrobat (PDF) format.

1.1.3. The JBER Telecommunications Installation Standard is generally developed to apply to end user building installations and how to provide service to them. In the case of infrastructure/utility type projects, or where work is being performed in a communications distribution node location such as an Information Transfer Node (ITN), a Remote Switching Terminal (RST), or Dial Central Office (DCO), additional design elements will apply and more specialized standards and practices will be imposed to meet the specific requirements associated with the large scale distribution of communications services to a given geographic service area on the base. It is suggested that design efforts, especially pre-RFP (Request for Proposal) efforts for communication node locations involve additional interaction with the 673rd Communications Squadron Plans Shop to ensure that a full understanding of the requirement is developed prior to bidding the project.

1.1.4. As part of any project in which a contractor is installing government furnished material or government stored material, the contractor will take on full responsibility for the operational capability of said material once it is installed. Although not specifically required, it would be to the contractor’s benefit to perform any appropriate acceptance tests (such as testing cable segments on the reel) to ensure the material is fully functional prior to installation of the material. If the installation does not pass final testing requirements, the contractor will be responsible for repairing/replacing the material and any installation practices necessary to create a fully functional installation. Any material being furnished by the contractor will be of new manufacture (less than six months old), in unused condition, and properly stored in an environment appropriate for the material (protected from UV radiation, extreme temperature swings, condensing moisture/standing water, etc.) unless specifically waivered, in writing, by 673CS/SCX Project Management. Any used/refurbished/old stock material proposed for use will be clearly identified as such as part of the proposal.

1.1.5. In cases where the project involves work with existing, operational cables (rerouting sections of cable through new paths, replacing/reinstalling distribution cables to facilities as part of renovation efforts, etc.), the installer/technician will test all the existing cable counts that are part of the project prior to any work taking place. The test results shall be submitted to the Government Point Of Contact (POC, defined specifically per each project) for analysis before

Controlled Unclassified Information 2 of 32 the work proceeds. After the cable work is completed, the installer/technician shall retest all cable counts affected by the project and return the cable counts to at least the same operational capability and performance level that existed prior to the work taking place.

1.1.6. Any project involving the demolition of existing facilities and communications support infrastructure will require that all telecommunications cable plant (copper, fiber optic, coaxial, etc.) be demolished back to the nearest service delivery point, such as a splice case in a manhole. At this location , the distribution cable count (copper pairs, fiber strands, etc.) will be spliced back into the main trunk cable so that the pair count is once again available the full length of the backbone trunk cable. In cases where the distribution count is coming off the end of a backbone cable count, the count will be recovered and prepared for future use, such as terminating with a pluggable, modular type splice for copper counts, or dressing out fiber strands in preparation for fusion splicing, then managing and sealing the counts in an approved splice case assembly. In addition, a minimum 14 day notice will be provided to 673CS/SCXP as to when service is no longer required by any tenants of the building and the 673CS work centers may enter the facility to remove any serviceable communications equipment, prior to the actual demolition of the facility taking place.

1.1.7. The organization performing the installation work (contractor, E&I team, etc.) is responsible for preparing the location(s) for any intermediate or final inspection/acceptance testing events. This will include, but is not limited to things like opening manhole lids, providing access ladders where needed, providing temporary lighting where needed, providing any tools necessary to open splice cases or other containers, providing any specialty protective equipment (protective slip on booties, etc.), meeting ventilation requirements, etc.

1.1.8. All labeling (cable ID tags, faceplates, patch panels, etc.) will use a standard, easily readable font such as Arial or Times New Roman in the production of the tags/tapes. Fonts that take on the appearance of a cursive script with varying line widths and/or curving lines in what would generally be a straight line segment of an alphanumeric character will not be accepted. Labeling of backbone OSP or Riser type cable segments will require labels where the cables enter/exit the main container (manhole, handhole, comm room, etc.) where they enter the termination point for that cable segment (protected entry terminal, splice cases, patch panel housings, etc.) and on each service loop. Labels will be oriented so they can be read from a practical distance and direction related to the container (standing a few feet in front of a telecommunications backboard, looking through a manhole cover, etc.) they are in and without having to uncover them from overlying cables. When new cables are installed near pre-existing cables, they will be installed in a manner that does not obscure existing labels. Label fonts will be large enough to be easily read from at least five feet away.

1.1.9. Unless specifically noted otherwise in the Scope Of Work, Performance Work Statement, or other similar document associated with a cable installation project making use of existing manhole/duct system, it is expected that the cable installation effort will be responsible for dealing with any environmental issues associated with installing the cable.

This includes, but is not limited to, items such as pumping standing water out of manholes, cleaning dirty duct/innerduct, thawing frozen ducts, installing missing pull ropes, or ventilating confined entry workspaces. If it is discovered and demonstrated there is an actual catastrophic duct system failure, such as a crushed or broken duct, the base will be responsible for returning that path to serviceability. Evidence of such duct failure will take into account seasonal conditions such as below grade frost line or frozen water in servicing manhole/handhole locations, hitting an apparent obstruction at approximately the same location when duct rodding from both ends of the duct segment, ability to duct rod an adjacent duct/innerduct, or ability to move a pull rope in an adjacent duct/innerduct.

If the project requires duct rodding a duct with an existing, active cable, coordination for this effort prior to the work being accomplished will be required with the 673CS Project Manager. When doing any work to proof or prepare a duct system for the cable installation, only tools specifically designed for this work will be used, such as duct rods of a minimum ½” diameter that are long enough to actually reach from one duct access point to the next access point.

When installing new pull strings or pull ropes in an empty duct, the acceptable methods are to either push a duct rod through the duct, then retrieve the pull rope by properly attaching to the end of the duct rod and pulling the duct rod back, or by using a pressurized air fishing system with the proper attachments, such as a Greenlee 591 power fishing system, or equivalent. No homemade or improvised tools will be allowed unless first approved, in writing, by 673CS/SCXP Project Management. When the project calls out for removing an existing cable and replacing with a new cable, often referred to as using the old cable as a pull rope, it is acceptable to use the old cable to pull in an appropriately rated pull rope behind it as it is being removed. The new pull rope will then be used to pull in the new cable sheath.

In the case of projects that are of a “turn-key” type nature in which virtually all material and labor necessary to create a fully functional communications infrastructure is to be provided by the installing entity, the project will include a cooperative engineering and project management effort with 673CS/SCXP project management section, in addition to the basic acquisition and installation of the material. This effort will provide, but is not limited to, items like an installation plan and time table for work at each location or phase of the project, as well as some specific location documentation such as rack elevation drawings or telecommunications backboard layouts showing the placement of new equipment, site plans showing proposed manhole/duct systems, etc. for approval prior to work proceeding. In addition, a proposed bill of materials will be provided for approval, prior to the acquisition of material for the project. The purpose of this approval is only for approving the type/quality of the material being proposed, not to validate quantities needed for the project.

Chapter 2

Outside Plant

2.1 Manhole duct systems

2.1.1. Manholes (MH): Manholes must be installed for all connections to the existing cable plant as required to maintain a maximum manhole spacing of 500 feet. Additional manholes may be required to provide adequate control of connection and distribution of the cable plant or to support significant direction changes in the duct path. All manholes shall be designed and constructed to meet the requirements of T.O. 31-W-3-10-22, and will be at least AASHTO M306 HS-20 traffic load rated.

Manholes being installed on or near an active flight line (runways, taxi ways, hard stands, etc.) will be Airport Rated. They will provide a clear floor spacing of 8’ X 10’ measured inside the manhole. An alternate size of 6’ X 8’ may be approved only when no primary backbone cable passes through the manhole (supporting lateral or dead end service only). All manholes are required to provide a clear internal height of no less than 7’-0”. Mandatory appurtenances include connected grounding bus bar and ground rod, related conductors and wiring, integral entry ladder or steps, cable rack supports (vertical brackets on walls, to be mounted using standoffs that will allow for approximately four inches of space between the wall and the bracket, capable of supporting the fully projected load of cables and splice cases, and step arms to support cables/splice cases. Any deviation from this will be considered on a case by case basis, such as smaller handhole installations), a 50 cubic foot sump (French Drain), pull in irons, frame, and a manhole cover cast with “Telephone” or “Signal” or “Communications” exposed to the surface. Generally the French Drain location in the manhole floor should be constructed as a “knockout” assembly in which all the grating and sump locations are cast into the floor while the bottom of the sump is still sealed with a layer of concrete that can be knocked out to allow for direct drainage into a properly prepared bedding layer under the manhole (minimum 6” thick gravel layer, etc). In cases where the water table is too high for drainage to be effective, the sealing layer can be left intact so that ground water does not readily infiltrate into the manhole. The cover shall be 36 inches in diameter. The cover will have at least one extendable ring or handle that stores in a recess, or some type of hole through the cover or full width/depth notch in the edge of the c0ver that allows for lifting of the cover with a standard manhole cover hook and a lip around the bottom of the cover that allows for dragging of the cover by use of a standard manhole cover hook.

Conduits shall enter the manholes approximately four feet above the floor (with the overall buried depth of the duct system below grade being the primary determining factor as to entry height) and shall enter the manhole perpendicular to the wall.

Conduit entries should be nearer the sidewall versus entering the middle of the end wall. This facilitates the flow of cable directly to the racking system instead of having to bend cabling sideways to the racking. See standardized drawing as an example of an acceptable manhole design and layout. Neck rings will be labeled with the unique manhole identifier assigned to that location. This labeling will take the form of stenciled alpha-numeric characters, painted with a black paint.

Characters to be approximately three inches tall.

2.1.2. Handholes (HH): When specified as part of a project as an alternative to full size manholes, handholes are required to be nominally 4’ X 4’ X 4’ inner dimensions and are provided with a grounding system, cable rack supports on each wall, sump drain, pulling irons, and handhole cover with identifying markings. All handholes shall be designed and constructed to meet the requirements of T.O. 31-W-3-10-22, and will be at least AASHTO M306 HS-20 traffic load rated. Handholes being installed on or near an active flight line (runways, taxi ways, hard stands, etc.) will be Airport Rated. The cover for this type of handhole will be a 36” round cover, similar to a manhole cover specified in 2.1.1. Basic design, construction and cable/conduit routing related to the hand hole must be the same as a manhole except on a smaller scale. Any questions should be directed to the 673 CS Project Manager. See standardized drawing as an example of an acceptable handhole design and layout. . Neck rings will be labeled with the unique handhole identifier assigned to that location. This labeling will take the form of stenciled alpha-numeric characters, painted with a black paint. Characters to be approximately three inches tall.

2.1.3. Manholes/handholes shall be constructed from a pre-cast waterproof concrete and be equipped with a removable cover.

If manholes/handholes are constructed in a manner that requires assembly of sections on site, assembly will require the use of an approved sealant for each joint location (joint seams in walls/lids, neck riser ring seams, etc.) such as Rub’R Nek LTM

RU106, Ram-Nek RN103, or equivalent. Manhole/handholes will be constructed to meet vehicular traffic load ratings as found on JBER Alaska, even if the initial installation will not be in a traffic prone area. Manhole/hand hole size and type is required to be specified as part of any design effort for review and approval by 673rd Communications Squadron Project Manager.

2.1.3.1 Occasionally long remote fiber optic cable runs will require periodic pull boxes along the run to facilitate service, repair, and access to the fiber optic cable. In these locations, it may be acceptable to use a lighter duty modular type pull box such as those produced by Hubbel (Quasite) or PenCell in a size that is appropriate to properly managing a service loop in the cable as well as a Preformed Fiberlign splice case. These locations will be addressed on a case by case basis and require written approval by 673rd Communications Squadron project manager.

2.1.4. A 3/4-inch X 10 foot copper clad steel grounding rod is required to be installed through the floor of each manhole/handhole provided. Four inches of the rod shall extend above the finished floor level. The rod must not enter the manhole more than 3 inches nor less than 2 inches out from the vertical surface of the adjacent wall. The installed ground is required to have impedance of 25 ohms or less. Single piece pre-cast manholes may require the grounding rod to enter through the duct window. Multiple piece manhole assemblies may need to have the ground rod installed through the floor, before the top section is placed. Cable bonding needs to be provided by the installing contractor in accordance with (IAW) T.O. 31W3-10-22.

2.1.5. Once installation of the manhole/handhole is completed, all penetrations will be sealed (ground rod penetrations, duct entry points through walls, ducts themselves, etc.) to prevent infiltration of ground water into the container. Each penetration type will be sealed with a method appropriate to the long term operation of the manhole/handhole container, ie. grout around conduit penetrations, removable plugs or expanding foam sealant in the mouth of empty ducts, expanding foam sealant in the ends of occupied duct or innerduct, etc. The expanding foam sealant will be of a type that sets up firm, does not remain sticky, and can be readily cut out as access is needed in the future. In addition, the MH/HH identification number will be stencil painted inside the neck of the container, just below the removable cover with characters that are at least four inches tall.

2.2 Conduits and Duct Banks

2.2.1. Cable Locate Tracing Wire: Where a non-metallic conduit material is used for buried duct, such as PVC or HDPE, a conductive tracer wire is required to be installed. In the cases of well grouped duct bank systems, such as four ducts in a tight 2x2 configuration, the conductive tracer wire will be installed on the exterior of the duct, approximately centered on the top of the duct bank. In cases where the ducts are spread out over a width greater than four ft., then a tracer wire will be installed on the exterior on each of the extreme outer ducts to enable locators to determine the width of the duct bank corridor. This wire will be an insulated 10AWG copper wire or larger. It will be looped around the duct every 20 feet, and securely taped to the duct every 10 feet. The wire will be extended into the manhole, and routed up the wall and across the ceiling to the manhole neck, so that it is accessible just by opening the manhole cover. In the case of multiple locate wires coming into the man hole, all wires will terminate in the same location in the neck of the manhole. The wires will all be connected together with a common electrical wire nut type connection, and each wire will be labeled as to the direction it leaves the manhole, and the far end point where the wire terminates (manhole, building, etc.) to allow easy identification and attachment of a tone generator to assist in future cable path location efforts. The tracer wire will be tested for continuity and functionality with a locater before acceptance. The contractor shall be responsible for all bonding to occur inside each manhole and at CER grounding frame. The tracer wire requirement applies both to structured manhole/duct systems (it is sufficient to mark a single duct run in the center of an overall bank of ducts) and to direct bury type innerduct (individual HDPE duct in the 2” to 1.5” size range). In cases where the innerduct is plowed in (versus being trenched in) an appropriate manner of installing the tracer wire with the duct will be determined, since taping and wrapping may not be feasible with that installation method.

Any deviations from taping and wrapping will require 673rd Communications Squadron Project Manager written approval. In addition to the tracer wires and other locating methods, each duct run, manhole location, direct bury innerduct run, direct bury cable run, direct bury cable splice location, or any other significant feature related to the buried cable plant will be surveyed using a GPS/GeoBase compatible survey device, such as a Trimble Geo XH unit to collect path and feature location information. The data will be provided in a format that is compatible with the ARCGis geobase database system being used by JBER and managed by the 673/773 CES Geobase Office (POC: Vikki Draper, 907-384-3519). This surveying will be done prior to backfilling so the actual locations can be precisely surveyed.

2.2.2. Conduit Routing/Warning tape: When a conduit/duct run cannot be run in a straight line and still enter a manhole or building perpendicular to the wall, conduits must be curved to provide gentle sweeps with a minimum radius of 25 feet to accomplish any necessary direction changes. The exterior conduit routing path will be such that short sweeps (60” type sweep) are not used to make the conduit entry point perpendicular to the wall at the very end of the run. Total amount of bends in a duct run segment will not exceed 90 degrees between manholes/buildings (to include any sweeps inside a building footprint, such as when a conduit arrives below grade and does not terminate directly into the CER, but must change direction to reach its ultimate destination in the CER). In the case were the conduit enters the comm room through the floor, the final vertical sweep up into room will be a minimum 48” radius sweep for a 4” ID conduit. Any sweeps within the building for a conduit system to support the extension of outside plant through the building will also use be a minimum of 48” radius for 4” ID conduit. All conduits are required to be sloped downward from the center of the run toward each opposing manhole at a slope of 3 inches per 100 foot of run to promote drainage of any accumulated liquids. In the case of the last segment between the building entry point and the servicing manhole, it is acceptable to maintain a continuous slope from the building down to the manhole at a grade of 3 inches per 100 feet to help prevent fluid draining into the building (still taking into account minimum bury depths for the whole length). Length of runs between building entry points and manholes, or between two manholes will not exceed 500 feet cable path distance. In instances where sharp turns in the duct path must be made, a manhole shall be installed at the corner, to facilitate safely redirecting the cable. All conduits or cables shall be buried at a minimum depth of one meter (40 inches) from top of conduit or cable to finish grade. The minimum conduit size will be 105 mm (4 inch) internal diameter, but may be larger, as needed, to meet specific requirements. Buried Cable warning tape shall be three inches wide, orange in color, and be used for direct buried cable applications, as well as conduit and direct bury innerduct installations, to mark cable pathways. Warning tape shall be installed 315 mm (12 inches) above the cable, conduit, or protective enclosure (sleeve, concrete encasement, etc.), whichever is highest. The tape will be marked with “Buried Communication Lines” or other approved marking to indicate that it applies to a communication line run, as opposed to some other type utility. In addition to these measures, all cables shall be fitted with permanent and corrosion resistant tags for identification purposes. Cable identification names will be coordinated with 673CS Project Management prior to installation of the identification tags.

2.2.3. All communications cables shall be installed in accordance with the guidelines indicated in T.O. 31-W-3-10-12. A copy of applicable section of this T.O. will be provided upon request of the contractor.

2.2.4. Conduit Bedding/layout: Generally conduit will be sand bedded between manholes with all appropriate bracing and installation practices being followed. In the case of the conduit path passing under a high load or high traffic area, such as under a road bed, parking lot, or aircraft taxiway or runway, the installation should be planned with some form of additional protection for the conduit, such as an overall steel sleeve or concrete encasing where it passes through the higher risk areas.

In cases where more that two duct are being run, steps will be taken to ensure the conduits within the duct bank are grouped to minimize the horizontal spread across the duct bank, to ensure accurate locates may be accomplished at a later date. It may also be appropriate to run the conduit at a deeper level through these areas to help minimize loading on the conduit system. Conduit runs shall be sized to account for all project cable requirements related to the project (or overall development of the area, whichever is greater), plus a minimum of one spare conduit. The conduit banks between manholes will be installed based on an even number of conduits, laid out in a grid pattern for entry into the manhole, such as two ducts wide by two duct tall pattern if four ducts are being installed between manholes. In a case like this, if two ducts were needed to support the actual requirements, the additional duct required for a spare would bring the minimum count up to three. Since the ducts will be installed in even numbers in a grid pattern, the actual installation required would be for four ducts in a 2 x 2 pattern. Any deviation from this approach will require written approval from the 673CS Project Manager.

2.3 Innerduct Installation

2.3.1. Innerduct installed:

Corrugated or ribbed innerduct shall be installed in any duct used for fiber optic cable.

Innerduct shall not have an inside diameter less than 1 inch.

Innerduct segments within a duct will be continuous, one piece sections. Splices will not be allowed.

Innerduct shall be sized for each fiber optic cable and have no less than ¼ inch air gap existing between the inside perimeter of the innerducts and the outside perimeter of the cable.

Controlled Unclassified Information 6 of 32

Innerduct shall be capped, plugged, or sealed and left with a pull rope tail tied off within the container if unused.

Innerduct through each manhole or cable vault shall be labeled and tagged with the data for the fiber optic cable installed or the word vacant for unused innerducts.

Vacant innerduct must contain a waterproof and corrosion resistant pull-rope (0.25 inch nylon or Kevlar mule tape) for future cable installations.

Contractor shall be required to install maximum number of innerduct possible when installing in a conduit raceway system. Ex: When running fiber through a 4” (i.d.) conduit in a backbone manhole/duct system, contractor would be required to install 4 pieces of one inch innerduct versus just the one required for the specific fiber optics cable.

The final 4” (i.d.) duct segment being used to support a fiber optic cable from the last manhole into an end user building will have three 1.25” innerducts installed. When installed, innerduct spares shall have nylon or polypropelene pull rope or Kevlar mule tape installed for future use/expansion. In some cases, dealing with older or smaller type duct banks that do not lend themselves to installation of standard innerduct, it may be acceptable to install a fabric type cable management duct liner, such as those produced by MaxCell. This will be determined on a case by case basis and require 673CS Project Manager written approval.

2.3.2. Exterior duct and communications cable system to support all valid requirements shall be installed from the facility’s communications equipment room(s) to the closest service connection point. This includes entry ducts, spares, conduits, and duct & manhole systems to the closest base service connection point. Provisions for crossing the roads and other paved areas are the responsibility of the contractor. When smaller diameter cables (such as a fiber optic cable) are being run through a larger duct (such as a four inch duct), the contractor shall use corrugated innerduct to first fill the larger duct (i.e. four 1” innerducts in a 4” duct). When smaller cables, such as a fiber optic cable or small count copper cable are being installed to an end user location without the benefit of a typical duct bank, a solid wall, toneable, direct bury, smooth outer/ribbed inner wall HDPE innerduct, with pressure rated couplings between segments will be installed between the service delivery point and the end user location to support the installation of the cable. The direct bury innerduct installation will include at least one spare buried innerduct and an external tracer wire will be buried along with the innerduct (as per 2.2.1). The innerduct will be pressure tested to insure the installation can support blowing fiber for the direct bury portions of the run. The direct bury innerduct will be a minimum size of 1.5 inch inner diameter. At any location where the duct run is not continuous between break out points (ie from building to manhole or between adjacent manholes), a buried marker ring such as a 3M p/n 1250 will be placed over the top of the duct ends, in addition to the associated tone locate wire being run to the end of the duct as well. This requirement applies to any place a duct or innerduct run ends underground, such as building stubouts, on both ends of a conduit placed under a roadway/rail bed, points where concrete encasement of buried duct ends, etc. This also includes both ends of a protective sleeve placed under a roadway or other structure that then has a direct bury cable or innerduct passing through it.

2.4. Exterior Entrance Cable System

The location and use of facility shall dictate whether the facility is connected via the copper plant or the fiber optic network, or both. The 673rd Communications Squadron (673CS) Project Manager (PM) shall specify what type and size of cable to use in connecting to the base communications plant, to meet the end user’s requirements. The installation or modification of any cable plant infrastructure needs to be viewed as an integrated system, made up of many components that have to work together to allow the infrastructure to perform as needed in a reliable manner that will meet all operational criteria and be efficient to maintain and repair as needed. This infrastructure must ultimately support many mission critical activities on base as well as being a component in supporting life safety operations, such as E911 capabilities. The design and specification of individual components needs to be looked at in the larger picture of how everything will integrate together as a working cable system, and not just be viewed as an individual component being purchased to operate in a discrete manner.

Fiber optic cable infrastructure systems will consist of items such as, but not limited to, fiber optic cable, protective sleeve components, ducting, splice equipment/material, termination connectors, termination panels, labeling systems and any other discrete components needed to create an overall working fiber cable infrastructure system. Likewise, copper cable infrastructure systems would consist of individual components such as copper cable, splice equipment/material, protected termination panels, surge protection plugs, house cable, termination blocks, grounding wire and connectors, protective ducting, and any other discrete components needed to create an overall functioning copper cable infrastructure system. The intent here is to not analyze and subsequently accept or reject any individual component without considering how it functions as part of an overall system.

2.4.1.1. Building entrance: Building entrance of communication cables for a new building, or a major renovation of an existing building, will be supported via 105 mm (4 inch) internal diameter duct from the primary communications room, extended to a minimum of 5 feet outside the building foundation. The exact number of these conduits will be determined on a case by case basis, but the minimum number will allow for at least one spare duct, above and beyond the number projected for initial use (there will always be at least two ducts installed). For buried duct that utilize a 90 degree sweep to enter up through the floor in a slab on grad type construction, a minimum of a 48” radius sweep will be used to facilitate the direction change from horizontal to vertical to enter through the floor.

These ducts will be filled with cable and/or innerduct as specified for an individual project. Any vacant duct will be appropriately capped and sealed, with ¼ inch nylon pull rope or Kevlar mule tape left installed for future use.

Typically the final duct segment from the building out to the first manhole would have one of the 105mm (i.d.) ducts filled with three – 1.5 inch corrugated innerducts.

2.4.1.2. Communications support path: Connection from a new building (or major renovation of an existing building) will be accomplished to the nearest service delivery point of the cable plant (copper and/or fiber as necessary). Typically to a manhole, but may be a direct bury splice point, or even back to the nearest telephone switch building or fiber distribution building, as necessary. This path will normally be supported by multiple 105mm (i.d.) duct between the building and service delivery point. On occasion it may be sufficient, or even more feasible to support the connection using multiple direct bury, HDPE, smoothwall, toneable innerduct (minimum nominal size of 1.5 inch). There will be a minimum of one unused innerduct planned into the installation design after all feeder cables are installed. This innerduct will enter the building via the 105 mm internal diameter entry ducts provided from the foundation entry point into the primary communications room. The entry duct will be filled with the maximum possible amount of innerduct, ie, a duct will not be left with only a single innerduct installed.

The unused innerduct will be plugged and sealed, with a nylon pull rope or Kevlar mule tape left installed for future use. In some cases, it will be necessary to run the 105 mm (4 inch) internal diameter duct continuously from the building entrance to the nearest manhole. This will be determined on a case by case basis. In cases where the duct must be run to the nearest manhole, no individual segment of the run will exceed 500 ft. If the overall duct run will exceed 500 ft, then additional manholes must be planned into the run to break up the lengths of each segment to be less than 500 ft. In addition, no individual segment will contain more than 90 degrees worth of bends. If a segment would require more than 90 degrees of bends, then additional manholes or handholes must be planned into the system to keep from exceeding this criteria.

2.4.2. Site prep for future activity: In cases where it is clearly known that there will be additional development work accomplished in the near future (additional buildings as part of complex, multiple buildings as part of an overall installation plan spread out through multiple years, etc.), basic infrastructure support for the area will be sized according to the overall requirement, and accomplished as part of the initial phase of the project. An example of this would be installation of a manhole duct system sized to support several buildings, not just the initial building, or backbone cables sized to support the projected overall requirements, not just to meet the minimum initial building requirement.

2.4.3. Leaving conduit under roadways: Anytime significant grade work and road work is being performed as part of the construction effort, future use of the area shall be considered by leaving multiple capped and marked 4 inch I.D duct under potential driveway crossings or parking lot crossings. The duct location will be captured on as-built outside plant drawings as well as the installation location will be geo-surveyed along with any other outside plant work in a manner to provide data that is compatible with the ArcGis database in use by 673/773 CES Geobase office. The duct will be installed to basic buried telecom duct standards (toning wire, proper bedding, warning tape, etc.). The location of each end of these duct segments will be marked with a buried metallic marker ring, compatible with Dynatel locating equipment (such as a 3M 1250 ring).

This will help prevent the need to cut up the paved surfaces at a later date to install new runs of cable through the area. These duct will extend a minimum of five feet past the road edge and will be protected similar to an active duct bank installation (concrete encasement, steel sleeve surround, etc.)

2.4.4. Running entrance conduit for alternate routing: Some buildings will be considered to be supporting critical missions. Once identified, these buildings will be required to have communications ducts run out multiple locations from the building. The exact location of these ducts will be determined on a case by case basis. This issue will be addressed as part of developing the operational requirements related to the project. This will require the organization developing the design criteria for the project to interact with 673CS Plans Office to determine the exact communications redundancy support required for the project.

2.5 Documentation of outside plant work: Any exterior work done with an associated project will be fully surveyed using approved GPS survey equipment and the information will be provided in a format compatible with the JBER GeoBase data base managed by the 673CES GeoBase Office. The surveying of the exterior work will take place prior to any backfilling

(trenches, pits, etc.) to ensure the most accurate survey path of the buried infrastructure. The geospatial coordinates for each unique communication feature (manholes, duct paths, distribution pedestals, splice points, buried sleeve termination points, cable paths, building entry points, etc.) will be located to within one (1) foot of its true ground position, in the horizontal plane, with a 95% spatial accuracy confidence level as defined in FGDC-STD-007.3-1998, specified in PWS Appendix 5.6.

Geospatial coordinates for the location of manholes and cable vaults shall be recorded for the center of the manhole lid.

Geospatial coordinates for the location of hand holes, pull boxes, pedestals, and buried splices shall be recorded for the top center of the feature. Geospatial coordinate data for the location of utility lines shall be recorded at a minimum every 10 feet and each turn or bend in a cable installation pathway must also be recorded so that the coordinates for any point along the turn pathway will fall within the allowable accuracy. The Contractor shall use GPS equipment and technology supplemented with electronic underground cable locating equipment and land surveying operations necessary to collect required Communication Feature Location Data (CFLD) following the Federal Geographic Data Committee (FGDC)-STD-007.4- 2002 specified in PWS Appendix 5.6. The Contractor shall be responsible for providing all required equipment including software, hardware, and any other tools, labor, and materials necessary to provide CFLD on electronic storage media in the specified formats. In addition, an electronic CAD type format as-built drawing set will be provided in a format compatible with Bentley Microstation Ver. 8 XM cad software. The drawing set will be provided in a format that can be edited using the Microstation software.

Chapter 3

Communications Equipment Room/Riser Closets/Cable Installation

3.1. The Communication Equipment Room (CER): The Main CER serves as the entrance facility for all communications services to the facility. Riser closets may be required to support backbone cable paths between CER locations. Satellite CERs serve to distribute those services throughout the facility. A CER may also serve as a riser closet. All facilities, regardless of size or intended use (with possible exception of guardhouses, utility control facilities, and storage bunkers) shall have a dedicated CER. Facilities with multiple floors or facilities in which communications outlets lay more than 90 meters in horizontal cable path length (not linear physical separation) from the closest CER shall have at least one satellite CER (SCER) per floor, and as many as necessary to keep the total cable length of the horizontal runs under 90 meters. Any room that actually supports the termination of any aspect of the cable plant, or houses any active electronic communications equipment will be considered a Communications Equipment Room (CER). A room will only be considered a riser closet if all the cables within the room are merely passing through the room and no cables are being terminated or spliced with in the room, as well as there being no active communications equipment housed within the room. These CER locations will be dedicated to the support of government, official communications systems and cabling. In general, all other disciplines and service providers (electrical, cable TV, etc.) will not be allowed in these rooms.

3.1.1. Location: The CER and riser closets must be located in the most central location available to keep the total maximum length of horizontal cabling under 90 meters. The main CER may be located in the basement or on the first floor in a location to provide the best service to the facility and riser closets. Riser closets on successive floors must be vertically stacked. In most cases it is desirable to have the riser closet function and satellite communications equipment room be the same room in a centrally located area of the building. Each floor with telecommunications requirements will have a CER (or satellite CER) to support requirements on that floor. The location of these CERs will be chosen with consideration for long term growth and maintenance, as well as the convenience and safety of the communications support personnel as they work on the equipment and move between the CER and end user locations. Depending on the floor layout and projected requirements, the satellite CER may take the form of an enclosed equipment cabinet located appropriately to support a specific zone. An adequate number of nominal 105mm (4-inch) diameter rigid steel conduits shall be installed between stacked riser closets to support user requirements and provide for 2 remaining spares. The CER shall never be co-located with electrical, mechanical, or HVAC facilities that have the potential to introduce electrical interference, moisture, gases, dust, or in any other way create an environment hazardous to the equipment being installed within the CER. In addition, every effort will be made to avoid having the CER and electrical service equipment (to include major circuit breaker distribution panels, transformers, electrical switch gear, etc) in adjacent rooms to prevent electromagnetic noise issues from impacting the communications equipment. In the rare case that a mechanical/utility room must be located adjacent to the CER, no electrical service equipment will be mounted on the shared wall and appropriate signage will be mounted on the wall in the mechanical/utility room to prevent the installation of this type of equipment at a later date. In no case will a CER or riser closet be used as a pass through path for any general utilities (plumbing, electrical, melt water, HVAC ducting, etc.).

In addition, no utilities or other items will be installed within the floor or walls (water lines, electrical conduits, etc.) of the CER that may prevent the future installation of equipment and subsequent anchoring of the equipment to the floor or walls anywhere within the room (i.e. the installation of anchor studs, sleeves, etc. to bolt down equipment racks and other

The only utilities that will have a presence within a CER or riser closet will be those necessary to support the requirements within the room itself (convenience outlets around the walls, light switches, etc.).

3.1.2. Size: The CER shall be approximately 1.1% of the total usable square footage of the facility. Riser closet size shall be approximately 1.1% of the floor space of the floor it serves.
