Glossary

Wire, cable, or conductors used for transmission of signals.

The process of vying for transmission time on the network media.

An impedance-matching device used to change the impedance of the cable to the expected impedance of the connected device. For example, media filters can be used in Token Ring networks to transform the 100 ohm impedance of UTP cabling to the 150 ohm impedance of media interface connections.

see G703

Any plane that includes or contains the optical axis.

A light ray that passes through the axis of an optical fiber.

A cable with a strong supporting member attached to it for use in aerial installations. See also figure-8.

Manual Electrical Tilt is where the antennas electrical tilt can be manually adjusted at the antenna. May be with or without motors.

Also known as Chrome Plastic.
Usually referring to hoods. Metalised is a painted coating over the plastic giving the appearance of a Metal hood and giving the plastic hood some conductive properties a cheaper alternative to a Metal hood.

An interconnected group of local area networks (LANs) that encompasses an entire city or metropolitan area.

Mast Head Amplifier - For ease “MHA” will be used when refereeing generically to all LNA (Low Noise Amplifiers) also referred to as TMA, ASC etc. This active DC powered device amplifies the uplink / receive signal as
near as possible to the antenna.

Feeder cable between MHA towards the main feeder

A pair of fiber-optic connectors that links the fiber media to the FDDI network card or concentrator. The MIC consists of both the MIC plug termination of an optical cable and the MIC receptacle that is joined with the FDDI node.

A connector that is used to link electronics and fiberoptic transmission systems.

A small radius bend in the optical fiber that changes the angle of incidence, allowing light to pass through the interface rather than reflect off it.
