The American Fibertek 1490E Series transmits high
quality video and simultaneously bi-directional RS422
data and contact closure on one multimode optical
fiber. The signals are transmitted using high
performance analog FM technology.

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 Cages: SR-20/2 or SR-20H/2 (redundant power
supplies) .
