The American Fibertek M3400C Series transmits high- quality video and
 simultaneously bi-directional RS422 data on one single mode optical fiber.
 Designed to be completely transparent to all camera and monitor
 manufacturers, this system requires no field adjustments at installation or
 additional maintenance thereafter. Diagnostic indicators provide a quick
 visual indication of system status.
 Equipment may be ordered as stand alone modules or rack cards that are
 mounted in the American Fibertek Card Cage: SR-20/2
