The American Fibertek 0500 Series is a low cost, low profile 20mA current

loop data transceiver system. Data transmit and receive is accommodated on

one multimode optical fiber. Designed to be completely transparent, this

system requires no field adjustments at installation or additional maintenance

thereafter.

I/O ports are selected by part number to be either active or passive. The units

have internal jumpers to allow independent setting of active or passive input

or output.

Transceivers may be ordered as stand alone modules or rack cards that are

mounted in the American Fibertek Card Cages: SR-20/2 or SR-20R/1.
