The ComNet CNMCSFP electrical-to-optical Ethernet media converters accept a 10/100 or 1000Mbps electrical input and converts this to a 100 or 1000Mbps optical output (selected by a dip switch) and the 100/1000Mbps optical input back to the 10/100/1000Mbps electrical output. "Auto-Negotiating" is supported on the copper interface side. These devices use either one or two optical fibers, depending upon the selection of sold-separately SFP† optical module. A PoE model, the CNMCSFPPOE/M meets the IEE802.3at standard and provides 30W of PoE+ power. The series consists of a small-size single channel model, CNMCSFP/M; a ComFit standard size, single-channel model, CNMCSFP; a dual channel model, CNMC2SFP; and a quad channel model, the CNMC4SFP.
