However, the materials used should be compatible with encapsulants so that they may be used as secondary protection if desired. Typically, these enclosures house and organize groups of fibers and accommodate splice trays, but have no patch panel capability.

Vehicular traffic shall be considered in order to determine depth of cover over the facility and whether concrete encasement is necessary. Direct burial is achieved by trenching, augering, boring, or plowing. The markings, if any, shall be visible during installation. The intent of these standards is to provide recommended practices for the design and installation of cabling systems that will support a wide variety of existing and future services.

All sizes of the closure and its intended encapsulant as system must not generate any exothermic condition that will damage the housing, cable insulation or connectors. Local political subdivision tax records and public works department plat records may be referred to for other classes of facility owners, such as private corporations, government networks, etc.


All have the capacity to house splice trays for protection of fibers. They shall be sized by calculating the number of splices, the amount and the density of the optical fiber and whether the cables are installed at one end or both ends of the splice closure.

Also, suitable corrosion resistant markers or cable tags showing appropriate facility owner operator information should be placed to facilitate visual identification of the fiber cable.

The terminal block manufacturer shall designate the recommended wire gauges for each block. Each situation must be evaluated in accordance tua the tunnel’s basic use, environment, and presence of other utilities to minimize the possibility of damage to the cable. To further ensure that gases do not enter the building, a venting system may need to be installed external to the building.



The primary considerations with such systems are the loading that the system places on the structure, and waterproofing of any eai points. Thus, the standardization process can reasonably be said to have provided at least a nine-year lifespan for premises cabling, and arguably a longer one. Access to the splice case, optical fiber equipment and, in some cases, 78 cable housed within is typically achieved through doors. Since building life cycles are typically planned for decades, technological electronic equipment upgrades are necessary.

578 Provisions are made to keep the encapsulant away from direct contact with the fiber. Under emergency or hazardous conditions, the excavator may proceed without prior facility owner s notification, using extreme caution to prevent facility damage, and should notify them eja soon as possible.

Telecommunications cable installed on aerial supporting structures such as poles, sides of buildings, and other structures. EIA agreed to develop a set of standards, and formed the TR committee, [3] with nine subcommittees to perform the work.

In addition, there are several extreme environmental and mechanical conditions to which a closure may be subjected in certain deployment configurations. Slope sleeves downward 10 mm per m o.

These documents are listed in table 4. A jumper connection to a cross-connect block shall meet electrical requirements for the smallest designated gauge after connecting and disconnecting the largest designated gauge. Compatibility with the environment can be achieved with enhanced cabling components or through protection, separation or isolation. This can be achieved by twisting the two conductors together after the splice is formed.

Customer-owned OSP connecting hardware may be located on the exterior or interior of a building, or in an outdoor telecommunications pedestal or cabinet. They are used to protect through splices continuation of a runbranch splices or to splice “drop” fibers to nodes. Extended periods of burial in soil should not degrade their mechanical characteristics, color, or markings.


Details are located at: Pathways or cabling between telecommunications service entrance rooms, equipment rooms, telecommunications rooms, or telecommunications enclosures within a building.

All metallic components of the cable, except for metallic transmission media, shall be bonded to each other and to ground. When terminated at the inside of the building wall, the conduit shall have a smooth bell-shaped finish unless it extends to a remote entrance room, space, or area.

Neither shall the existence of such Standards and Publications preclude their voluntary use by Non-TIA members, either domestically or internationally. The owner should notify the excavator when no facility will be affected by the excavation. Retrieved from ” https: From Standards Proposal No. The facility owner should respond promptly when notified by the excavator that a facility’s markings have not been preserved.

The customer-owned OSP cabling infrastructure shall meet the requirements of the authority having jurisdiction AHJ and applicable codes.

Since attenuation is related to the diameter of the cable, larger cables are selected for longer installations or when it is desired to reduce the number of amplifiers in a link. These documents are listed in table 3. The colors of the wire pairs in the cable, in order, are: The standard defines categories of unshielded twisted pair cable systems, with different levels of performance in signal bandwidth, insertion loss, and cross-talk.

The width of this zone, if not specified by the state damage prevention law, should be mm 18 in. Fibers are typically spliced to factory prepared connector pigtails that are loaded into patch panels. Optional consolidation points are allowable in horizontal cables, often appropriate for open-plan office layouts where consolidation points or media converters may connect cables to several desks or via partitions.
