ComNet ComFit Dual 10/100/1000Mbps Ethernet Media Converter with IEEE 802.3at 30W PoE+ - 1 x Network (RJ-45) - Gigabit Ethernet - 10/100/1000Base-TX, 1000Base-FX - 120 km - 2 x Expansion Slots - SFP - 2 x SFP Slots - Power Supply - Rail-mountable, Standal

The ComNet Ethernet CNMC2+1SFP electrical-to-optical Ethernet media converters accept two 10/100 or 1000 Mbps electrical inputs and converts this to a single 100 or 1000 Mbps optical output (selected by a DIP switch) and the 100/1000 Mbps optical input back to the 10/100/1000 Mbps 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. The ComNet exclusive Demux feature allows for port isolation, replicating two media converters over one fiber. The ComNet exclusive Mux feature prevents network video flooding of multicast traffic with DIP switch selection of the fiber port as a dedicated uplink path. The CNMC2+1SFP series can be powered by wide range of AC or DC input power supplies.
