From Telecommunications Cabling Installation, Second Edition


Cable termination involves organizing cables by destination, forming and dressing cables, and proper labeling, as well as actually creating a connection with a copper or fiber conductor. This chapter describes the methods, tools, and applications for terminating copper and optical fiber cables. It lists pretermination steps and addresses several different applications relative to the termination of a cable, including:

  • Termination blocks.

  • Patch panels.

  • Telecommunications outlet/connector.

  • Direct connection.

  • Copper cable.

  • Coaxial cable.

  • Optical fiber cable.

The following types of cable currently recognized by the ANSI/TIA/EIA-568-B.1, Commercial Building Telecommunications Cabling Standard, Part 1: General Requirements, for use in the premises cabling are covered in this chapter:

  • 100 twisted-pair copper cable

  • Multimode optical fiber

  • Singlemode fiber

Undercarpet flat cable is designed for installation under carpeting. Undercarpet cable will make a transition from round horizontal cable to flat cable in a transition box, usually at a wall. The work area (WA) termination is the same as for other work area outlets. It should be noted that the length of undercarpet cable should meet the following recommendations for data circuits:

  • Avoid high traffic areas.

  • Keep the undercarpet cable as short as possible (10 m [33 ft] is the recommended maximum length).

  • Maintain at least 150 mm (6 in) clearance from power circuits.

  • If power circuits must be crossed, the cross should be at right angles and above the power circuit.

Products & Services
Network Wiring and Cabling Services
Network wiring and network cabling services install copper and fiber optic cable within buildings or central offices.
Cable Laying Services
Cable laying services install fiber optic cable or copper cable in buildings and office complexes, or over large distances.
Ethernet Cables
Ethernet cables are designed to support Ethernet, a standard protocol for the connection of computers in a local area network (LAN). They use twisted pair cables and modular connectors, and are designed to run at 10 Mbps, 100 Mbps, or 1 Gbps.
Fiber Optic Cables
Fiber optic cables are composed of one or more transparent optical fibers enclosed in protective coverings and strength members. Fiber optic cables are used to transmit "light" data.
Fiber Optic Connectors
Fiber optic connectors are used to align and join two or more fibers together to provide a means for attaching to, or decoupling from, a transmitter, receiver, or other fiber optic device.
