CHAPTER 1 TELECOMMUNICATIONS BUILDING CABLING SYSTEM

1-1 OVERVIEW

This UFC is intended to provide a telecommunications manager with a means for designing new Building Cabling Systems (BCS) or additions to existing BCS. Sufficient reference material is provided to allow for a basic understanding of a BCS and the components. The provisioning of telecommunications support for MILCON projects is outlined in MIL-HDBK-1190. This guide is intended to address only the requirements for BCS telecommunications pathways and cabling necessary to support voice, data and video systems required for new and renovated facilities. This UFC will establish an implementation concept that can be used to shape architectural templates and influence the design process for Installation Information Infrastructure Architecture (I3A). It will identify proven infrastructure construction techniques, define common practices, and serve as an authoritative implementation guide.

This UFC is consistent with Department of Defense (DoD) Policy Memorandum of June 29, 1994, regarding the use of commercial standards in lieu of military specifications. Unless otherwise specified by the major claimant, or where deemed inadequate for safety reasons, or inappropriate because of the function of the facility, commercial standards must be employed in the planning, design and installation of inside cable plant in support of U.S. Army U.S. Navy and U.S. Air Force sponsored military construction and refurbishment projects. A partial listing of Commercial, Federal and DoD standards, that addresses telecommunications design and installation practices, are provided in Appendix A. The major claimant and the BCS Engineer must jointly review this list to confirm the adequacy of the commercial standards to meet the telecommunications requirements of the particular facility.

1-5 SCOPE

This UFC is intended to support the necessary requirements gathering, site surveys, analysis, design and implementation of Information Technology. This guide specifically assists the designer in the integration of the building cabling system. Note: Each service handles telecommunications and information technology funding in different ways. This UFC does not address the funding responsibilities and procedures for military construction projects. Refer to the specific services construction program guidance for funding issues.

CHAPTER 2 BUILDING TELECOMMUNICATIONS CABLING SYSTEM SPECIFICATIONS

The BCS is designed to satisfy Army Installation Information Infrastructure Architecture (I3A) policy, UFC 3-580-10 Design: Navy and Marine Corps Intranet (NMCI) Standard Construction Practices Information System (IS), and Engineering Technical Letter (ETL) 02-12: Communications and Information System Criteria for Air Force Facilities requirements within a facility. The BCS must be installed in accordance with the Telecommunications Industry Association (TIA) and Electronics Industry Alliance (EIA) Building Telecommunications Wiring Standards general guidelines with modifications and clarifications provided below. TIA/EIA specifications can be purchased at http://www.tiaonline.org/standards/. Telecommunications design must be performed and stamped by a Registered Communications Distribution Designer (RCDD) for all projects. For projects that involve the Navy Marine Corp Intranet (NMCI), coordinate infrastructure design with UFC 3-580-10 Design: Navy and Marine Corps Intranet (NMCI) Standard Construction Practices. For projects that involve the US Air Force coordinate infrastructure design with ETL 02-12.

2-1 CLASSIFIED INFORMATION INFRASTRUCTURE

Engineers engaged in the design of classified (collateral or higher) Information Infrastructure must coordinate the infrastructure design with the Certified TEMPEST Technical Authority (CTTA) and Designated Accreditation Authority (DAA) responsible for that area. This Technical Guide cannot attempt to replace the publications that have been produced to support the design of Red/Black infrastructure. The engineer must consult the following applicable documents for consideration and design guidance: NSTISSAM TEMPEST/2-95 (FOUO) defines the guidance to consider during design and installation, and provides potential solutions, DCID 6/1 and 6/9 (U) define the physical security requirements in construction of secure facilities, NSTISSP 300 (U) provides the National Policy on the Control of Compromising Emanations, and NSTISSI 7003 (U) provides guidance on Protected Distribution Systems. NSTISSAM TEMPEST/2-95 states that the National Policy on the Control of Compromising Emanations (NSTISSP 300) and its implementing instructions, TEMPEST Countermeasures for Facilities (NSTISSI 7000), and NONSTOP Countermeasures (NSTISSI 7001) establish the policy that certain systems and facilities that process national security information (NSI) must be reviewed by a CTTA, and AI PUB-5239-22 Information Assurance Protective Distribution System (PDS) Publication FOUO for Navy projects. If a CTTA review is required, and the review determines that TEMPEST countermeasures are required, the CTTA will consider a variety of methods that can be applied to the system/facility to achieve TEMPEST security. The RED/BLACK guidance contained in NSTISSAM TEMPEST/2-95 (FOUO) will be considered by the CTTA along with other measures (e.g., TEMPEST Zoning, TEMPEST suppressed equipment and shielding) to determine the most cost-effective countermeasures to achieve TEMPEST security. Only those RED/BLACK criteria specifically identified by the CTTA will be implemented. Additional information on grounding can be found in MIL-STD-188-124B and MIL-HNBK-419-A. Information on Protected Distribution Systems can be found in NSTISSI No.7003, 13 December 1996.

2-2 SYSTEM OVERVIEW

An acceptable building cabling system encompasses: copper and fiber optic entrance cable, termination equipment, copper and fiber backbone cable, copper and fiber horizontal distribution cable, workstation outlets, racks, cable management, patch panels, cable tray, cable ladder, grounding, and labeling. Figure 1, of Appendix B, provides an overview of the cable entrance and backbone distribution. Figure 2, of Appendix B, provides and overview of the horizontal distribution.

2-3 WORKSTATION OUTLET

The following specifications pertain to telecommunications outlets and connectors:

2-3.1 Outlet Box Specify double gang electrical boxes of at least 2-1/8” (54 mm) depth to provide dedicated space for current and possible future fiber optic cable installation. For single connector outlets, such as voice-only, cable television (CATV) or closed circuit television (CCTV), use a single gang 2” by 4” by 2-1/4” (51 mm x 102 mm x 57 mm), electrical box recess mounted, with the faceplate flush with the wall surface. Locate a service power outlet within 6 inches (152 mm) of all outlets. The power outlet circuits must be based on a loading assumption that each location of two duplex receptacles will power one personal computer with a monitor along with typical office appurtenances such as task lights; also assume that there will be no diversification of this load. For Navy projects, utilize 4-inch (102 mm) square by 2-1/4 inch (57 mm) deep boxes for single gang, four outlet copper telecommunications configurations that do not have provision for fiber optic cabling. For Army projects, specify 4-11/16-inch (119 mm) square by 2-1/4 (57 mm) boxes for 1-inch (27 mm) conduit installations and outlet boxes that have or may require fiber optic cabling.

2-3.2 Outlet Faceplate Use a full (double gang) faceplate for standard administrative outlet locations, with connectors for all copper and (if used) fiber optic cable. Standard administrative outlets may, by specific user request, use single gang outlet faceplates in conjunction with a reducing ring. For single gang outlet boxes, use a single gang outlet faceplate with appropriate connector locations and, if required, mounting lugs for wall phones. Outlet faceplate must include two blanks position for future applications.

2-3.3 Outlet Connectors The following specifications pertain to copper, fiber optic and coaxial cable outlet/connector. The category for cable, jacks, termination blocks, and patch panels must be the same throughout each circuit and system. Specify more than one category only if providing more than one system requiring different categories. In general for horizontal cable, use Category 6 for all voice and data circuits on Army and Navy projects, and use Cat 5 or better for USAF projects.

2-3.3.1 Copper Outlet/connector Copper outlet/connector must be TIA/EIA category 6 (Cat 6) for Army and Navy projects, and Cat 5 or better for USAF projects.. All connectors must be 8-pin/8-position insulation displacement terminations wired per T568A. The T568B configuration must only be used by exception if required to maintain system configuration uniformity, security or other user-specified reasons. Category 3 (Cat 3) rated connectors must not be used in new construction, or rehabilitation projects. Copper outlet/connector and plugs should be unkeyed unless the user requires keyed outlet/connector and plugs to maintain system uniformity, security, or other user specified reasons.

2-3.3.2 Fiber Optic Outlet/connector Terminate all fiber optic work area cables in dual 568SC connectors. Provide fiber optic connectors in accordance with the paragraph entitled “Fiber Optic Terminations” in this UFC. The default choice for fiber optic outlet/connector must be TIA/EIA “SC” type (568SC). Other type connectors (small-form-factor) (MT-RJ, VF-45, etc.) may be substituted as required by the user. Small form factor connectors (available from several manufacturers), offer a potential for significant installation cost reduction. Any type of fiber connector used must meet the performance requirements specified within Annex A of TIA/EIA-568-B.3, and meet the requirements of the corresponding TIA Fiber Optic Connector Intermateability Standard (FOCIS) document.

2-3.3.3 Coaxial Outlet/connector Coaxial outlet/connector should normally be “F” type connectors. Use of other type connectors (i.e., BNC, etc.) should be considered only if specifically required by the user. The designer must coordinate with the cable service provider where franchise agreements are in place. The Navy requires that all passive CATV devices support 1 GHz bandwidth.

2-3.4 Outlet/Connector Markings Each communications outlet must have a unique identifying number in accordance with TIA/EIA 606-A. In the telecommunications room (TR), this unique identifying number must be associated with the position on the patch panel or cross-connect to which the outlet is connected. Each horizontal cable must be labeled both at the outlet and patch panel or cross-connect position in the communications closet. Connector voice and data dedication use may be reassigned as requirements dictate. Note: in the standard cabling scheme, the designations “voice” and “data” are arbitrary and do not imply that one outlet is better than the other, the outlets are identical in capability.

2-3.5 Outlet Types and Density The following outlet types are commonly used in military construction projects. Sketches of these outlets are included in Figure 6, of Appendix B. The outlet types do not cover all possible user required configurations. The designer must certify that all user-defined outlets have a corresponding valid requirement, such as fiber for various levels of classification. Outlet configurations must comply with this UFC, TIA/EIA-568-B, and TIA/EIA-569-B. Outlet densities are provided for planning purposes, when actual outlet locations are not known and cannot be determined with available information. The designer can develop reasonably accurate total outlet count estimates based on the size and dedicated usage of the space. These factors fall within the ranges given in TIA/EIA-569-B, and are based on gross area (overall building footprint without deducting for hallways, equipment rooms, restrooms, etc.). See Figure 9, of Appendix

B, for a typical building floor plan. For USAF projects all administrative facilities and administrative spaces in other types of facilities must be equipped with one standard telecommunications outlet for each 48 square feet (4.5 square meters) of net office space. Outlet densities and locations for all special-purpose spaces and non- administrative facilities must be determined by the user and the BCSO and must follow the guidelines in TIA/EIA-569-B.

2-3.5.1 Family Housing Units

2-3.5.1.1 Army Family Housing

The designer must determine the minimum outlet quantity for Army Family Housing (AFH) units based upon the number of rooms in the AFH unit. In general provide one telephone outlet and one CATV outlet (as a minimum) in each of the following rooms: kitchen, living room, dining room, family room/area, each bedroom, and any other logical location deemed appropriate. Copper outlet/connector must be TIA/EIA category 6 (Cat 6) for Army and Air Force projects.

2-3.5.1.2 Navy Family Housing

The designer must provide a complete structured telecommunications system in accordance with TIA/EIA-570-B for Navy family housing units. Provide Grade 1 wiring for units with less than 1500 square feet (140 sq m) and Grade 2 wiring (excluding optical fiber) for units with 1500 square feet (140 sq m) or more. Locate the distribution device adjacent to the residential load center. In addition to outlet locations required by TIA/EIA-570-B, provide two outlets on opposite walls in the living room, family/great room, den/study, and each bedroom. Provide one outlet in dining room and garage if provided. Copper outlet/connector must be TIA/EIA category 6 for Navy and Marine Corps Intranet (NMCI) projects.

2-3.5.1.3 Air Force Family Housing The designer must provide a complete structured telecommunications system in accordance with TIA/EIA-570-B for Air Force family housing units. Residential Telecommunications Cabling Standard Telephone outlets must consist of 4-pin/4- position non-keyed CAT 3 or better modular USOC RJ-11 jacks. CATV outlets must be “F”-type jacks. Locate jacks in the kitchen, living room, family room, and all bedrooms adjacent to a 120-VAC, 60-Hz (or host country standard voltage and frequency as applicable) duplex electrical receptacle. Telephone and CATV outlets must be wall- mounted. Locate outlets or provide additional outlets to enable maximum furniture placement flexibility.

2-3.5.1.4 Barracks/Bachelor Quarters For Army barracks projects provide one 8-pin modular (RJ45 type) connector in a single gang outlet faceplate, labeled voice use. In BEQ/BOQ/SEBQ/etc, provide one single RJ-45 outlet in each room of the suite; i.e., bedroom & living room, configured per TIA/EIA-570-B. For Navy projects provide two telecommunications outlets for each resident on opposite walls consisting of two 8-pin modular (RJ45 type) outlets wired per

T568A, except in open bay berthing. For example: a 1+1E suite is designed to house 1 occupant by assignment therefore a minimum of 1 separate line and 2 outlets on opposite walls are required. A 2+2 suite is designed to house up to 2 occupants; therefore 4 outlets (two per room) are required. For Air Force quarter’s telephone outlets must consist of 4-pin/4-position non-keyed CAT 3 or better modular USOC RJ-11 jacks. CATV outlets must be “F”-type jacks. Locate jacks in the kitchen, living room, family room, and all bedrooms adjacent to a 120-VAC, 60-Hz (or host country standard voltage and frequency as applicable) duplex electrical receptacle.

2-3.5.2 Systems Furniture Wiring The designer must specify a minimum of one systems furniture outlet per single occupancy cubicle. The designer must specify a minimum of two systems furniture outlets per cubicle designated for servers, printers, copiers or faxes. When systems furniture is installed as part of the construction contract, insure that systems furniture specifications include TIA/EIA-568-B and TIA/EIA-569-B cabling and raceway standards.

2-3.6 Utility Rooms and Closets

All utility rooms and closets, such as electrical, mechanical and telecommunications, must be wired with at least one wall mounted telecommunications outlet, with a mounting lug face plate.

2-3.7 Elevators

For buildings with elevators, a four-pair copper cable with an eight-position modular outlet adapter must be installed for each elevator. The exact location of the outlet assembly must be verified with the elevator installer or Contractor.

2-3.8 Safety, Courtesy, & Convenience

Provide wall outlets at all logical locations to support safety, courtesy, & convenience. Examples include safety: barracks hall, laundry room; courtesy: building lobby/entrance, stairways; convenience: break rooms, rear (unmanned) entrances.

2-3.9 Building Automation Systems When requested by the building support systems planner, provide wall outlets at identified locations to support building automation systems. For example, one such outlet may be a direct digital controller (DDC) outlet for the HVAC system. The IS/IT- designer does not have primary responsibility for identifying these circuits, and should defer to the building support systems planner.

2-4 BUILDING TELECOMMUNICATIONS WIRING

The following information pertains to horizontal cable and backbone cable. All horizontal and backbone wiring must be designed in a star-configuration as defined in TIA/EIA- 568-B.1. All Cables must be terminated within telecommunications rooms, telecommunications equipment rooms, and work areas.

2-4.1 Horizontal Cable The following information pertains to copper and fiber optic cable and cable run lengths.

2-4.1.1 Copper Voice and Data One Category 6 (for Army and Navy) or one Category 5 or better (for USAF) unshielded twisted pair (UTP) cable must be installed to each standard 8-pin modular connector provisioned at the outlet. For example, install two 4-pair UTP cables to a standard administrative outlet, or one 4-pair UTP cable to each single connector outlet. Copper cables must not be split between multiple modular connectors. Use only cable that has passed the Underwriters Laboratory (UL) LAN certification program and is labeled with UL acceptable markings. Plenum cables must be provided in accordance with National Fire Protection Association, Inc. (NFPA) 70, or when directed by the facility safety officer or local building code. Provide terminations in accordance with the paragraph entitled “Copper Termination” in this UFC. The designer must not use 150 ohm shielded twisted pair for new construction. Category 3 (Cat 3) rated cable must not be used in new construction, or rehabilitation projects.

2-4.1.1.1 Copper Termination Terminations must be performed using an 8-pin (RJ45 type) connector, rated for the category of the installed cable. In a standard cabling scheme, horizontal cables are arbitrarily designated “voice” and “data” to identify and differentiate their purpose. Copper distribution cable must be terminated at the TR on 110-type cabinet or rack- mounted patch panels compliant with Category 6 for Army and Navy projects, or Category 5 or better for USAF projects. Very small projects (i.e., one or two phones) may use a TIA/EIA Category qualified block or backboard mounted patch panel. Cables from the same outlet must be terminated on the same patch panel and individually identified. All terminations must be wired to the TIA/EIA T568A configuration. Do not use T568B wiring configurations unless specifically requested by the user and approved by the authority having jurisdiction. Copper cables must not be split between multiple modular connectors.

2-4.1.1.2 Copper Patch Cables Copper patch cables must be 4-pair, 24 American Wire Gauge (AWG) stranded UTP cable, rated for Category 6 (for Army and Navy) or Category 5 or better (USAF), with 8-pin modular connectors at each end. Provide sufficient copper patch cables, of various appropriate lengths, to terminate all copper patch panel appearances.

substituted as required by the user. Plenum cables must be provided in accordance with NFPA 70, or when directed by facility safety officer or local building code.

2-4.1.2.1 Fiber Optic Termination All fiber optic distribution cable must be terminated in cabinet/rack-mounted patch panels, and at the outlet. Do not use ST style adapters for new construction unless specifically required for interface with existing equipment reused on installations. Check with activity for specific requirements for ST adapters. The default choice for fiber optic adapters and connectors must be TIA/EIA “SC” type (568SC). TIA/EIA 604-3A “SC” type connectors are preferred in new systems as the international standard now accepted by the Federal Government. Other type connectors (small-form-factor) (LC, MT-RJ, VF-45, etc.) may be substituted as required by the user. Provide fiber optic adapters and connectors in accordance with TIA/EIA-604 Fiber Optic Connector Intermateability Standard (FOCIS) and the corresponding FOCIS for the type of connector used.

2-4.1.2.2 Fiber Optic Patch Cables Fiber optic patch cables must be using the same fiber optic cable type and connectors as the patch panels they are interconnecting. Duplex patch cables must be used.

Provide sufficient fiber optic patch cables, of various appropriate lengths, to terminate all fiber optic patch panel appearances plus 25% spare.

2-4.1.3 Cable Length Copper data cable length must be limited to 295 feet (90 m) from patch panel termination in the TR to the data outlet termination in accordance with TIA/EIA-568-B.1. Adjust the average cable length for planning purposes as required (i.e., average measured length). Exception: buildings with collapsed backbones that use fiber optic cables for all data and copper UTP for voice-only, may exceed the 295 foot length.

2-4.2 Backbone Cable The following subparagraphs pertain to copper and fiber optic backbone cable. The building backbone must have no more than two hierarchical levels of cross-connects. Copper backbone cable must be used only for voice circuits. Data backbone circuits must be fiber optics.

2-4.2.1 Copper Backbone Cable Multi-pair voice backbone cable must meet the requirements of Insulated Cable Engineers Association (ICEA) S-80-576 and TIA/EIA-568-B.2 for riser rated unshielded twisted pair cable. Conductors must be solid un-tinned copper, 24 AWG. The copper backbone cable originating in the main TR or main cross connect must be terminated in each TR on 110 type, insulation displacement, wiring blocks mounted on the telephone backboard. Provide at least two backbone cable pairs for Army projects and 1.5 pairs for Navy projects, for every outlet connected to the TR served by the backbone cable. Plenum cables must be provided in accordance with NFPA 70, or when directed by the facility safety officer. ICEA specifications are listed in the references, and can be purchased at http://global.ihs.com.

2-4.2.2 Copper Termination Termination must be performed using an 8-pin (RJ45 type) connector, rated for the installed cable. All terminations must be wired in accordance with TIA/EIA T568A. In a standard cabling scheme, horizontal cables are arbitrarily designated “voice” and “data” to identify and differentiate their purpose. Twisted pair OSP cable is terminated on the Protected Entrance Terminal (PET). See Figures 4 and 5, of Appendix B, for details. Cross-connects can then be placed from the PET to the first set of 110-type terminal blocks as needed. The first set of terminal blocks provides connection for all backbones and for outlets served by the main TR. For example, in a three-floor building, one backbone cable must be terminated on 110-type blocks on the same backboard as the PET; one backbone cable should be terminated on 110-type blocks in the 2nd-floor TR; and one backbone cable should be terminated on 110-type blocks in the 3rd-floor TR. A backbone cable connects a second set of 110-type blocks in each TR to a rack mounted, 8-pin (RJ45 type) connector voice patch panel. This panel can be patched to the distribution patch panel, which in turn terminates the Category 6 (Army and Navy) or Category 5 or better (USAF) outlet wiring. Cross-connects can be done by the DOIM/BCSO/Telephone personnel, and jumpers can be installed by the user/Information Mission Area (IMA) department, providing the desired connectivity between the OSP and the inside plant wiring. This design allows maximum flexibility for future moves, additions, and changes.

2-4.2.3 Fiber Optic Backbone Cable For all Army and NMCI projects, a minimum of 12 strands of 50/125-micron or 62.5/125- micron multimode fiber optic cable and 12 strands single mode fiber optic cable must be installed between the main telecommunications room or main cross connect and each TR. If requested by the user, only 12 strands of one type of fiber may be used. For Navy projects, except medical facilities, a minimum of 12 strands of 50/125-micron or 62.5/125-micron multimode fiber optic cable must be installed between the main telecommunications room or main cross connect and each TR. Navy medical facilities require 12 strands single mode and 12 strands of 50/125-micron or 62.5/125-micron multimode fiber optic cable between the main telecommunications room or main cross connect and each TR. Plenum cables must be provided in accordance with NFPA 70, or when directed by local regulations. For all USAF projects the backbone cable must be 12-strand, 62.5/125-micron multi-mode FOC. The backbone cable must be terminated in a patch panel with duplex SC-type connectors installed in an equipment rack or cabinet

Note: The Army Gigabit Ethernet data network architecture dictates the use of single mode fiber optic cable between TRs.

For Navy projects a general guideline in premises applications for backbone cabling is as follows:

� Single-mode fiber is recommended for greater distances or higher data rates:

2-4.2.3.1 Fiber Optic Termination All fiber optic backbone cable must be terminated in cabinet/rack-mounted patch panels, at each end. Do not use ST style adapters for new construction unless specifically required for interface with existing equipment reused on installations. Check with activity for specific requirements for ST adapters.
