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.

Features for CNMC2+1SFP Series

  • Link Fault Pass-Through feature detects if either of the copper ports are down and triggers the optical port to switch states to indicate the failure to the head-end.
  • Optical port supports 100/1000 Mbps full duplex data
  • Full size units feature a contact closure output for remote side link failure detection
  • IEEE 802.3 compliant
  • Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required.
  • Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events.
  • ComFit standard form factor is interchangeable between stand-alone or rack mount use.
  • Uses customer-installed ComNet SFPs for compatibility with a wide range of optical fibers, optical connector types, and optical transmission distances (SFPs ordered separately).
  • Electric Port Supports Auto-negotiation for Full Duplex or Half Duplex Data Throughput
  • Standard ComFit models are hot-swappable.


  • Optical transmission of Ethernet-compatible industrial security access control systems, intercom systems, VOIP (Voice over IP) telephony networks, and IP-compatible CCTV camera surveillance networks
  • Optical Ethernet transmission to wireless LAN access points
  • Optical transmission of any Ethernet-compatible equipment with a maximum data rate of 100/1000 Mbps
