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 CNFE200(X) series can be powered by wide range AC or DC input.

Features for CNFE2MC Series

  • Optical port supports 100 Mbps full duplex data
  • Distances up to: 3 km (2 mi) Multimode 20 km (12 mi) Single Mode
  • ST or SC optical connectors
  • 1 or 2 fiber design
