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. Editable documents will be provided in Microsoft Word or Excel 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 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. 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.

1.1.4. 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.

1.1.5. All labeling (cable ID tags, 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. Label fonts will be large enough to be easily read from at least five feet away.

1.1.6 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.

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 traffic load 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. Manholes being installed on or near an active flight line (runways, taxi ways, hard stands, etc.) will be Airport Rated. 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 traffic load rated. 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 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

2.1.4 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. Cable identification names will be coordinated with 673CS Project Management prior to installation of the identification tags.

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 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 installed:

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.

• Innerduct/HDPE will be cut off to no longer or less than 12”-15” from entering manhole 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 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. The drawing set will be provided in a format that can be edited using the software.

3. Copper Installations

3.1 Backbone/Outside Plant Connectivity: Connectivity to the base copper distribution system will be determined on a case by case basis. In areas where it is determined that a connection to the base copper backbone is required, the minimum cable size run to the building will be 25 pr, 24AWG. The cable requirements may be increased dependent on the expected end building requirements. Any outside plant copper installed as a main distribution cable, or as an outside plant feeder cable, inside a manhole duct system, to tie a building to a distribution trunk cable will be an RUS PE-39 specification direct bury rated cable such as Superior-Essex SealPic-F type cable, minimum 24 AWG, with the pair count sized according to the defined requirements of the project. Outside/direct bury rated cables will be routed into the protected terminal entry equipment from the bottom side, to ensure that the open end of the cable is facing up to prevent the gel filling from running out as the cable warms up over time. Unless otherwise defined, all new cable segments will include all terminations and splices necessary to create a fully functional cable path from the end user building to the appropriate telecommunications service node (direct cable connectivity, splices into existing trunk cables, etc.). Splices will be accomplished using a pluggable splice module, similar to a 3M MS*2 4005 product. In cases where a cable is being installed through an existing path that does not contain sufficient existing cable management systems to properly support and protect the cable from stress or bend radius violations (cable racking brackets with load bearing standoffs and step arms in manhole/handholes, interior cable tray/J-hooks, waterfall accessories, etc.), the installation of this material will be included as part of the cable installation project. In addition, cables will be fully tested and labeled throughout the cable path, to include ensuring each access point container (manhole, handhole, etc.) is properly labeled as well. The minimum effort for full and complete labeling will include a machine printed tag attached to the cable sheath at each point where the cable enters or exits the container and where a sheath enters a splice case or termination panel, as well as ensuring the container itself (stenciling inside manhole necks, etc.) is properly identified and marked. The exact label format and information content will be provided for each project by the 673CS Project Manager. Installation personnel will coordinate with 673CS Project Managers for specified pair counts in trunk cables, cable naming conventions, scheduling of potential cable outages, etc. In cases where there is no copper backbone capacity in the nearby vicinity capable of servicing the building, it may be necessary to implement an outside plant cable infrastructure project to supply this capability to the general area. When a project of this nature is implemented, any cable that is installed shall not leave any cable segments with ends exposed below grade. All cable segment ends will be enclosed within an appropriate splice case, even the very end segment of a cable run that is merely being prepositioned to support a follow on construction project.

3.2 Testing/ Inspection and Acceptance (Copper): A basic visual examination of the installed cable plant will take place prior to any formal testing. The examination will look for signs that proper installation techniques were not used. The visual inspection will include, but is not limited to, looking at cable bend radius, proper cable support, separation from sources of electrical interference, signs of kinking, stretching, damage to cable jackets, or snagging of cables during installation, or any other sign that basic installation standards were not adhered to for a given cable type. Once the visual inspection is passed, all conductors in each cable will be tested to standards applicable to the rated performance standards of the cable type. In cases where work is related to existing, active cables, all conductors will be tested before and after the work, once appropriate down time is scheduled for any active circuits that may be routed through the cable. The organization performing the tests will be responsible for removing and re-establishing cross connects as necessary to perform the necessary tests and return the cable(s) to service once down time has been coordinated.

4. Fiber Optic Cable

4.1 Outside Plant Connectivity: Outside plant (OSP) fiber optic connectivity for the building will be accomplished by a minimum 12 strand Single Mode (SM) loose tube, dry water blocked direct bury rated type cable. There will be a minimum 15 meter (50 ft.) service loop left on each end of the cable, as well as every third access point container such as manholes, handholes, and pullboxes that the cable may pass through. The maximum diameter of service loops within a pass through, access point container will be three feet, unless a larger diameter is required to meet the minimum bend radius diameter specified by the cable manufacturer. Service loops will be individually created, bundled, and mounted, ie when multiple cables are installed through the same location as part of a project, they will not be coiled up together. The service loop coil will be strapped (tie wrap, hook & loop strips, etc.) as appropriate for the installation environment. Each service loop will also have a cable ID tag fastened one each side of it, on the cable sheath as it enters/exits the loop. The minimum effort for full and complete labeling will include a machine printed tag attached to the cable sheath at each point where the cable enters or exits the container and where a sheath enters a splice case or patch panel. Fiber patch panel labeling will, at a minimum, reference cable name, strand count, and far end location (building number, room number, etc.) of each cable segment terminated within the panel. The exact cable naming scheme will be provided by 673CS. Any proposed deviation from this setup will be addressed on a case by case basis and will require written approval by 673CS Project Management prior to implementation.

4.1.1 Testing/ Inspection and Acceptance (Fiber): A basic visual examination of the installed cable plant will take place prior to any formal testing. The examination will look for signs that proper installation techniques were not used. The visual inspection will include, but is not limited to, looking at cable bend radius, proper cable support, signs of kinking, stretching, or snagging of cables during installation, or any other sign that basic installation standards were not adhered to for a given cable type. Violation of any of these standards or any sign that a cable has been stressed during installation is grounds for rejection of the installed cable plant. Once the visual inspection is passed, all strands will be tested to standards appropriate to the performance rating of the installed cable type. In cases where work is related to existing, active cables, all strands will be tested before and after the work, once appropriate down time is scheduled for any active circuits that may be routed through the cable. The organization performing the tests will be responsible for removing and re-establishing cross connects as necessary to perform the necessary tests and return the cable(s) to service once down time has been coordinated.

4.1.2 Test Plan: A Test plan defining required tests and type of test equipment to be used during testing is required to ensure the system meets technical, operational, and performance specifications. The proposed test plan shall be submitted for review 60 days prior to the proposed test start date. The test plan must be approved before the start of any testing. The test plan shall identify the capabilities and functions to be tested as well as an outline of detailed instructions for setting up and executing the test plan. Additionally, the plan is required to outline the procedures for evaluating and documenting the results of the test. The test plan will also address any specific issues related circuit down time and removal/replacement/relocation of patch cords supporting existing circuit requirements that may be impacted by the test procedure. Once actual test dates are determined, 673CS/SCXP will be given at least a seven calendar day advance notice, with the option to observe the test procedures.

4.2 Test Reports and As-Built Prints: Test reports shall be submitted in booklet or CDROM format with witness signatures verifying execution of all tests listed in the test plan. Reports shall show the field tests performed to verify equipment compliance with specified performance criteria. The test reports will include a record of all physical parameters verified during testing. At a minimum, test reports will include power loss insertion measurements for each direction of each strand (two values for each strand) for each wavelength, as well as OTDR traces for each direction on each strand for each wavelength. In addition, the raw data collected by the test equipment will be copied to an optical disk and be provided. Test reports will be submitted to 673rd Communications Squadron Project Management Office for submission and review by the 673 CS OPR, usually O & M Activity, within 14 days after completion of testing. When fiber optic cable installation includes outside plant installation work, as built drawings will also include butterfly drawings of each container showing the utilization of all ducts and innerducts in each container. The butterfly drawings may be in the form of a neat, legible sketch and do not necessarily have to be in an electronic CAD type format. In the case of the installation of any specialty equipment that directly supports communications requirements, additional as built drawings will be provided as needed to fully document the installation of the equipment (such as WAP antennas in Hangar bays, or on the exterior of a building, etc.). The format of any as built documentation will conform to those listed in section 1.1.2. In addition, any electronic versions of as-built documentation will be supplied in a version that is fully capable of being edited at a later date (i.e., a CAD drawing will be provided in an unlocked/ungrouped format so that individual items can be edited or more readily merged into existing floor plans. Adobe PDF or similar documents that cannot be edited are not an acceptable format for as-built documentation.).

4.2.1 Materials & Documentation: Materials and documentation to be furnished under this specification are subject to inspections and tests. All components must be terminated and labeled before testing for final acceptance. Equipment and systems will not be accepted until the required inspections and tests have been made, demonstrating that the signal distribution system conforms to the specified requirements, and that the required equipment, systems, and documentation have been provided. To support this initiative, an appointed 673rd Communications Squadron Quality Control (QC) representative shall observe operational tests, and analyze both observed and annotated test results provided by the contractor.

Any system, equipment, or hardware that does not meet Department of Defense (DOD), manufacturers, or ANSI TIA/EIA standards as appropriate will not be accepted. All discrepancies must be re-tested/re-inspected and the results certified correct in writing by the 673rd Communications Squadron QC representative prior to any final acceptance.

4.2.2 Fiber Optic Cable Testing: Unless stated otherwise, tests must be performed from both ends of each strand, including those with active circuits in the case of work on an existing cable, once appropriate down time has been scheduled. Test results for each individual circuit path segment (contiguous fiber strand between connectors, or from an individual connector to the end of a strand in case of drop dead counts) and direction of test will be presented individually. Connectors will be visually inspected for scratches, pits, chips, or contamination and must be cleaned, re-polished, or re-terminated if any of these conditions exist. Each multimode circuit leg and complete circuit will be tested for insertion loss at 850 and 1300 nm using a light source similar to that used for the intended communications equipment. Each single mode circuit segment and complete circuit path will be tested for insertion loss (power loss test) at 1310 and 1550 nm using a light source similar to that used for the intended communications equipment, and showing a flat response across the frequency spectrum. In addition to the insertion loss testing, fiber backbone/riser and outside plant cables will also be tested similarly (same wavelengths, from both ends of the fiber strand, etc.) using an Optical Time Domain Reflectometer (OTDR). Scale of the OTDR trace will be such that the entire circuit appears over a minimum of 80 percent of the X-axis. Acceptable loss for fiber splices (fusion type splicing) is between 0 and 0.25 dB. Acceptable loss for connector interfaces (i.e. mated connector pairs such as patch panels, etc) is between 0 and 0.5 dB. The maximum acceptable reflectivity for any measured anomaly

(connectors, splices, etc.) is 30 dB. The connector losses will be measured without any special effort to align the connector faces, i.e. jiggling or rotating a connector to try to get a better reading. The overall loss budget for the run will then be calculated based on the actual advertised attenuation budget for the cable being installed as a function of distance, at the wavelength being tested (i.e. 0.3 dB/km for Corning ALTOS single mode cable at 1550nm, multiplied by the length of the cable in km), plus the maximum allowable loss due to the number of splices plus the maximum allowable loss due to the connector interfaces under test, etc.

In cases where a new distribution cable is being connected to an existing trunk cable, such as a mid-sheath opening (cable tap/splice) or splicing on to specific strands at the end of the trunk cable, the strands that are part of the specified splice effort will be tested as specified above. A trunk cable would be considered to be any cable in which all strands terminate at the same node building on one end, but various strand counts are broken out and delivered to (or planned for delivery to) different end user locations. In addition, all other strands within the trunk cable that are not supporting active circuits will also be tested with an OTDR to ensure no damage was inflicted on these strands during the mid-sheath opening and splicing operations. Any blatant damage or anomalies noted within 100 ft. on either side of the splice location, as measured by the OTDR, will be grounds for an appropriate remediation effort to the trunk cable. The scope of this effort will be dependent on the exact location and type of problem identified via the testing process, but could range from reworking existing splices to replacing complete cable sections. Installing short sections throws in a fiber optic cable path which add additional splice points and cable sheath vulnerabilities to an overall run will not be deemed an acceptable remedy to a new cable installation that does not pass initial testing, nor to fix an existing cable that is damaged as part of an installation effort.

Any pre-installation test results generated as part of the project to validate the condition of the fiber cable prior to work commencement will also be provided to the 673CS/SCXP project manager. Any damage or performance issues noted before work begins will be addressed and appropriate actions will be determined prior to work proceeding. If no pre-installation tests are performed, then all risk will be assumed by the installing entity and any damage or out of specification test results will require corrective action by the installing entity prior to project acceptance by the 673CS. This will apply to all strands within the same cable sheath that is directly involved in the project.

Typical Installation drawing attachments: The drawings shown in this section should be used as a functional example of rack layouts, telephone backboard layouts, cable interconnectivity between CERs, manhole/handhole construction formats, etc. This drawings should not be used directly as design/installation drawings for any specific project. Drawings specific to each project will need to be developed based on requirements and local conditions identified for each project, but these drawings should serve as a design template for the creation of the specific project drawings. Electronic versions of these drawings are an Adobe PDF version on request, however, due to the nature of the conversion from a CAD format to the PDF, resolution and clarity of the drawings in the PDF format can be expected to suffer some degradation.
