CCT100x is a reliable and densely packed media converter designed to connect network equipment to test equipment. It's built-in, hard wired conversion goes from 100BaseT copper to 100BaseFX fiber with virtually no latency. It also features a loopback mode for diagnostics and a setting to force a copper to fiber link or leave its fiber link active even when there is no copper device actively attached. Each port can be named and tracks temperature and electrical current draw on the optic transceiver. By watching these parameters, the overall circuit can be checked for trouble. A 4 port and 24 port unit are available, both 1U high. The 4 port can be double banked in 1U.
