talking face to face is full duplex, meaning that they
can both talk and listen simultaneously. The Eclipse
matrices provide full-duplex audio.

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.
Fixed Group
In a Fixed Group communication configuration, an
operator speaks to all members of a group at once, in
the manner of an announcer. However, if a group
member responds by calling the operator back with
their answer-back key, the audio path goes to the
operator panel only. This mode can be contrasted with
a conference or partyline configuration in which all
members of a group can speak to all other members at
the same time.

Interruptible Foldback. The term foldback refers to

other announcers, videotapes of commercials, or some
mix of sources, while they on the air. This is typically
found in television news and live broadcast events.
