The CLFE4US1TPC by ComNet Communication Networks of Danbury, Conn., is an Ethernet switch that combines four 10/100TX Ethernet signals and transports them over one coaxial cable or RJ-45 cable.
The product can extend the transmission distance to 1,500 meters using coax or 900 meters using RJ-45 cable. It is designed for applications where existing copper media, such as coaxial cable or twisted pair (UTP) is currently installed and an upgrade to an IP-based system is required.
