IntroductionThe Westermo ODW-631 is a fibre optic modem designed for point to point fibre 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 fibre link depends on selected transceiver and fibretype.Fibre distances up to 80 km (50 miles) are possible using singlemode fibre.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 fibre optic link.
