Glossary

Any telephone building where switch systems are located. Also called exchange office or central office.

Extraction Tool - A small device (Metal or Plastic) used to remove contact/s from a connector insulator.

When describing a fiber-optic connection, the portion of loss that is not intrinsic to the fiber but is related to imperfect joining, which may be caused by the connector or splice, as opposed to conditions in the optical fiber itself. The conditions causing this type of loss are referred to as extrinsic factors. These factors are defects and imperfections that cause the loss to exceed the theoretical minimum loss due to the fiber itself (which is called intrinsic loss).

RF Coaxial connector, The Type F is similar to the Type G except it is threaded rather than snap-on. Primary applications are for cable television (CATV), set top boxes, and cable modems.

A type of coaxial RF connector used with coaxial cable.

A type of laser used in fiber-optic transmission. The Fabry- P

Also known as Bezel or Facia.

Part of an outlet unit that sits on a wall or inset within the floor of an office. The Bezel is the frame or a face onto which you can fix various interfaces to create the connection points needed.

A plate used in front of a telecommunications outlet. See also wall plate.

A multifiber cable that is designed for easy connectorization. These cables are sometimes sold with installed connectors or as part of a splice pigtail, with one end carrying many connectors and the other installed in a splice cabinet or panel ready for splicing or patching.

A collection of components used to add tight buffers to optical fibers from a loose tube buffer cable. A fanout kit typically consists of a furcation unit and measured lengths of tight buffer material. It is used to build up the outer diameter of fiber cable for connectorization.

The end of a twisted pair cable that is at the far end with respect to the transmitter, i.e., at the receiver end.

Crosstalk that is measured on the nontransmitting wires and measured at the opposite end from the source. See Chapter 1 for more information on various types of crosstalk.

A unit of capacitance that stores one coulomb of electrical charge when one volt of electrical pressure is applied.

A phenomenon that causes some materials to rotate the polarization of light in the presence of a magnetic field.

Ethernet standard supporting 100Mbps operation. Also known as 100Base-TX or 100Base-FX (depending on media)
