The annex also recommends responsibilities and procedures for damage-prevention activities on the part of excavators and facility owners. HSCs are generally required for deployment in the buried or underground plant and in any other deployment scenario where exposure to chemicals or corrosive agents is expected.

Such a closure, however, permits the free exchange of air with the outside environment.

Additionally, it is recommended that spare capacity be included to support present and future applications. A jumper connection to a cross-connect block shall meet electrical requirements for the smallest designated gauge after connecting and disconnecting ansu largest designated gauge.

When entrance route diversity is developed, entrance routes should be separated by the greatest possible distance.

Handholes are smaller than maintenance holes and are typically used as cable pulling points. See entrance room or space telecommunications.

All of the component sealants and parts shall be compatible with petroleum jelly and other types of filling compounds.

Due to the variety of designs encountered in OSP construction, it is not possible to establish link or channel requirements for these applications. The recognized media include: By such action, TIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publication.


A ria installed under the surface of the ground in such a manner that it cannot be removed without disturbing the soil. Specific requirements are found in the normative clauses of this Standard.


For the purpose of this Standard they are termed, customer-owned OSP. Tapes should be at least 50 mm 2 in. Protection is to be provided by sealing all entering cables and drop wires in a 75 without the use of secondary encapsulants for protection.

A topology in which telecommunications cables are distributed from a central point. Details should also include the location of abrupt deviations taken from the cable’s normal planned route and placing depth. General a identification; b working height; c Size LxWxH ; d Covers and frames; e ladders; f g grounding rod; h exposed straps required for bonding to the grounding system as required by applicable electrical codes or practice for all metallic reinforcing members e.

Vehicular traffic shall be considered in order to determine depth of cover over the 78 and whether concrete encasement is necessary. They shall not produce significant galvanic corrosion effects, in wet or humid conditions, or on other metals likely to be present in pedestal terminal closures or aerial cable terminals.

The demands placed upon commercial wiring systems increased dramatically over this period due to the adoption of personal computers and data communication networks and advances in those technologies. The physical or logical arrangement of a telecommunications system.

Marking of owners facilities Marking exceptions Offset staking and marking Special situations Call for assistance Marking materials 67 The generic items and procedures for restoration work include: They shall eis produce significant galvanic corrosion effects, in wet or humid conditions, on other metals likely to be present in their use environment. The use of warning tape above service or drop lines on private property is optional. The zone where excavation is to be performed with hand tools or nondestructive tools until the facility is exposed or the maximum depth of the intended excavation is reached.


They should be resistant to fungi, heat, solvents, and stress cracking agents and compatible with metals and other materials such as conductor insulation and filling compounds used in the manufacture of cable. Each pair of the distribution cable is connected to a pair of contacts on a distribution cross-connect block. All standards are subject to revision, and parties to agreements based on this Standard are encouraged to investigate the possibility of applying the most recent editions of the standards published by them.

These markers should be identified with the name of the facility owner and one or more telephone contact numbers to obtain the precise fia location.

Separation of the fiber cable from other utilities on the bridge should be in accordance with the provisions of the National Electrical Safety Code or other appropriate regulations. Customer-owned OSP connecting hardware may be located on the exterior or interior of a building, or in an outdoor telecommunications pedestal or cabinet. In addition, all metal supporting members and all electrical shields and ground wires of all terminals shall be electrically bonded so that hazardous voltages are directed to ground.
