The ODW-621 is a fiber optic modem designed for point to point
fiber optic applications between devices with an RS-232 interface.
The ODW-621 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 the fiber link depends on selected transceiver and fibertype.
Fiber distances up to 50 miles (80 km) are possible using singlemode
fiber. The unit has a retiming function that eliminates the problem
of jitter and hence ensures reliable communications in all
situations. It is possible to use the ODW-621 in conjunction with
the ODW-631 to provide protocol conversion from RS-232 to RS-422/485
at either end of the optical link. |
