The ODW-622 is a fiber optic modem that can be used to create
either redundant ring or multidrop fiber optic solutions for devices
with RS-232 interfaces. The ODW-622 is designed for harsh industrial
usage as well as road or railway installations meeting industrial
level EMC specifications and having a wide operating temperature
range. The maximum distance of a fiber link depends on selected
transceiver and fiber type. Fiber distances up to 50 miles (80 km)
are possible on each leg of the ring meaning huge rings over 621.4
miles (1000 km) in circumference could be created. The unit has a
retiming function that eliminates the problem of jitter and hence
ensures reliable communications in all situations. The unit has LED
indication to display fault conditions as well as relay contacts
that can be connected to a PLC or similar device to allow network
problems to be diagnosed at a central point. It is possible to mix
ODW-622 with ODW-632 in a network and hence have both RS-232 and
RS-422/485 devices in the same network. For a multidrop network it
is possible to use the ODW-621 or ODW-631 as the endpoints. |
