ComNet CNFE100: Ethernet Media Converter, 10/100Mbps, 1 Channel, 1 or 2 Fibre, Multimode or Singlemode

Product Code: CN-CNFE100*


The ComNet Ethernet media converters are one-channel Ethernet electrical to optical media converters. These auto-negotiating devices accept a 10/100Mbps electrical input and convert this to a 100 Mbps optical output. This series of media converters is suitable for use with multimode or singlemode fibre and one and two fibre.

The media converters have LED indicators to show operational status. All models are environmentally hardened with no electrical or optical adjustments.  Packaged in the exclusive ComNet ComFit housing, the standard size units may be either wall- or rack-mounted. The units are powered by an 8-15Vdc power supply which is included.

These media converters are tested & certified by an independent laboratory for full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions and transient voltage protection) of NEMA TS-1/TS-2 and CALTRANS Traffic Signal Control Equipment Specifications
