The American Fibertek 487 Series transmits and receives two
channels of RS485 data (2 wire or 4 wire user configurable) or RS422
data or 1 of each over a single multimode optical fiber. The system is
comprised of two transceivers forming a point-to-point
communications link. The system is designed to be completely
transparent to data protocol. For ease of installation, 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, SR-20/2
or SR-20R/1.
