The ComNet Ethernet CNFE100X media converter series are one-channel Ethernet electrical to optical media converters. These auto-negotiating devices accept a 10/100Mbps electrical input and convert this to a 100Mbps optical output. This series of media converters use multimode and single-mode optical fiber and one and two fiber SC and ST optical connectors. LED indicators confirm operational status. All models are environmentally hardened with no electrical or optical adjustments (Plug and Play). Packaged in the exclusive ComNet ComFit housing, the standard size units may be either wall or rack mounted. Models within the series are also available in a small size. The units are powered by an included DC power supply.
