SHORT HAUL FIBER INTERFACE (MA-600)
The MA-600 is a Short Haul Fiber Interface Module that can be used with the RFL DS562NC
Synchronous Data Module. The Short Haul Fiber Interface Module is a single width module, and
consists of an input section (detector) and an output section (emitter). The module is mounted at the
rear of an RFL IMUX 2000 chassis, directly opposite the DS-562NC module. The input power
requirement is +5 Volts at 175 mA maximum from the chassis supply. The input drive signals are TTL
logic-level, generated by the DS-562NC. The Short Haul Fiber Interface (MA-600) can only occupy
one time slot at a data rate of 64kbps.
