The ComNet Ethernet CNFE200X media converter series are two-channel Ethernet electrical to optical media converters with optional PoE+. These auto-negotiating devices accept two 10/100 Mbps electrical inputs and convert this to a single 100 Mbps optical output. This series of media converters are available as multimode or single-mode and one and two fiber SC and ST optical connectors. 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 CNFE200X series can be powered by wide range AC or DC input while the CNFE200XPOE units meet the 802.3at standard and provide 30 watts of PoE+ power, with an option for a 60 watt CNFE200XPOEHO model. The PoE models can be powered by a sold seperately 48 to 57 volt DC power supply.
