The American Fibertek 485T Series transmits, receives, and repeats high-
quality, RS485 data on dual multimode optical fibers. Designed for
continuous long-range, interference free data
transmissions,
these systems
require 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-20/1 or
SR-20R/1.
