Glossary

The ability of a material to allow the flow of electrical current; the reciprocal of resistivity. Measured in

A material or substance (usually copper wire) that offers low resistance (opposition) to the flow of electrical current.

A rigid or flexible metallic or nonmetallic raceway of circular cross section in which cables are housed for protection and to prevent burning cable from spreading flames or smoke in the event of a fire.

A cone-shaped region extending outward from an optical fiber core and defined by the core

A set of standards adopted by European and other countries, particularly defining interface standards for digital signals.

A basic part of any telecommunications distribution system. Also called a terminal block, a punch-down block, a quick-connect block, and a cross-connect block, a connecting block is a plastic block containing metal wiring terminals to establish connections from one group of wires to another. Usually each wire can be connected to several other wires in a bus or common arrangement. There are several types of connecting blocks, such as 66 clip, BIX, Krone, or 110. A connecting block has insulation displacement connections (IDCs), which means you don

A communications protocol that uses acknowledgments and responses to establish a virtual connection between sending and receiving stations.

A communications protocol that does not create a virtual connection between sending and receiving stations.

With respect to cabling, a device attached to the end of a cable, receiver, or light source that joins it with another cable, device or fiber. A connector is a mechanical device used to align and join two conductors or fibers together to provide a means for attaching and decoupling it to a transmitter, receiver, or another fiber. Commonly used connectors include the RJ-11, RJ-45, BNC, FC, ST, LC, MT-RJ, FDDI, Biconic, and SMA connectors.

Normally DIN 7-16 (may be N-Type) pair, one male and one female making the connection of 2No components. Sometimes the ‘male’ connector is a right angle.

With respect to fiber optics, a device used to terminate an optical fiber.

With respect to fiber optics, the fixed or stationary half of a connection that is mounted on a patch panel or bulkhead.

With respect to fiber optics, the maximum value in decibels of the difference in insertion loss between mating optical connectors (e.g., with remating, temperature cycling, etc.). Also known as optical connector variation.

With respect to fiber optics, the part of connector insertion loss due to impurities or structural changes to the optical fiber caused by the termination within the connector.
