The ODW-631 is a fiber optic modem designed for point to point
fiber optic connections between RS-422/485 networks or devices. The
ODW-631 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 80 km (50 miles) 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-631 in conjunction with
the ODW-621 to provide protocol conversion from RS-232 to RS-422/485
as well as the fiber optic link. |
