the comNet™ FDX72(m,S)1SHR series Self-Healing Ring transceiver unit is
a fully-digital transceiver designed for implementing full RS232, RS422 or
RS485 2 or 4-wire traffic signalization/communications data networks of the
highest possible reliability. A network of FDX72SHR units can support one full-
duplex data channel or two half-duplex data channels. Full data re-clocking and
regeneration permit an almost unlimited number of transceiver/controller units
to be used within the network. these environmentally hardened transceivers are
ideal for use in unconditioned out-of-plant or roadside installations.
utilizing wave division multiplexing technology (WDm), only one optical fiber is
required between units to implement a fully self-healing ring. two FDX72SHR
units can be used in a redundant point-to-point topology.
Bi-color (Red/Green) lED indicators are provided for rapidly ascertaining
equipment operating status including the location of fiber breaks. See
Figure 7

for an explanation of lED indications.
these units are interchangeable between stand-alone or card-cage mount
configurations. See
