From Telecommunications Cabling Installation, Second Edition


This chapter describes supporting structures and associated hardware that may be required in a telecommunications cabling installation project. It provides an overview of the methods necessary to properly lay out and install support equipment in telecommunications spaces and pathways.

Telecommunications spaces and cable pathways must have the proper support equipment to make the installation function properly. The equipment needed is shown in the following table.

Table 3.1: Support Equipment Needed

Telecommunications Spaces

Cable Pathways

  • Backboards

  • Ladder racks

  • Conduit

  • D-rings

  • Cabinets

  • Equipment racks

  • Ground bars and wires

  • Cable trays

  • Conduit

  • Surface-mounted raceways

  • Slots

  • Sleeves

  • J-hooks

Particular emphasis must be paid to the requirements of the most recent editions of the American National Standards Institute (ANSI), Telecommunications Industry Association (TIA), and Electronic Industries Alliance (EIA) Standards 568-B.1, B.2, and B.3; 569-A; 606; and 607 when planning and installing this infrastructure.

Proper design of the components described in these standards leads to a successful initial installation and makes future additions and rearrangements possible. Failure to adhere to these requirements may cost hours or even days of delay or additional work to complete the job, which will have a financial impact.

The components identified in this chapter are readily available from a variety of manufacturers and vary in size, color, configuration, and cost. The cabling installer must become familiar with the various manufacturers products and how they adapt to individual installation requirements.

While this chapter is not intended to identify the entire range of products available to meet a specific need, the...
