The ODW-611 is a fiber optic modem designed for point to point fiber optic connec-tions between PROFIBUS-DP networks.The ODW-611 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 ODW-611 is able to automatically detect the data rate of the connected PROFIBUS-DP network and hence needs minimal configuration prior to use.The unit also has a retiming function that eliminates the problem of jitter and hence ensures reliable communications in all situations.
