Balun Cable Dual Coax to RJ45 G703

Dual Coax to RJ45 Balun Cable Assembly

Balun Cable assemblies provide a low cost, flexible solution for the connection of balanced 120 ohm twisted pair interfaces to an unbalanced 75 ohm coax network. Compatible with 2Mbit/s E1/T1 and 8Mbit/s E2/T2 data streams. The 120 ohm, 2 pair, foil screened cable is terminated at one end in a shielded RJ45 plug, complete with strain relief boot. The other end is split into two legs, each leg is over sleeved, labelled TX and RX respectively and terminated in Coax Balun connectors.
