The Dual Coax to RJ45 Balun Adapter range is a compact, easy to install, reliable solution for connecting a balanced 120 ohm RJ45/RJ48C twisted pair interface to an unbalanced 75 ohm coax network. Compliant with ITU-T G.703 recommendation, the Balun Adapter provides bi-directional signal conversion, impedance matching and isolation protection. Suitable for 2Mbit/s E1/T1 and 8Mbit/s E2/T2 data streams.
Balun Adaptors are also available for mounting on a Bulkhead Plate.
