The American Fibertek 82B Series multiplexes 16 total channels (8 in each
direction) of dry latching contact closure on one multimode fiber. Individual
channel LEDs on the transmitter and the receiver units indicate the channel
status.

The contact output relays are latching which maintain their states when either
optical power is removed (fiber disconnected) or the fiber modules lose DC
power. A reset button is available to clear all contact status to the default
state.

These systems require no field adjustments at installation or additional
maintenance thereafter. Diagnostic indicators provide a qu ick visual i ndication
of system status.

Equipment may be ordered as stand alone modules or rack cards that are
mounted in the SR-20/2 or SR20H/2(redundant power supply) AFI Card
Cage.
