FIM-102D FIBER INTERFACE

GLOSSARY

fiber-optic cable

A fiber-optic cable consists of a glass core covered with a reflective material called “cladding” and

several layers of buffer coating to protect the cable from the environment. A laser sends light pulses through the glass
core to the other end of the cable.

full duplex

Refers to transmission of signals in two directions simultaneously.

interface

A piece of electronic hardware designed to convert the 4-wire signals of a central matrix port to some

other form of communications, such as 2-wire party line, telephone, etc. The interface is connected to a central matrix
port. The external non-4-wire device is then connected to the interface.

mode

A term used to describe a light path through a fiber as in multimode or single mode.
