G703 Balun Adapter Dual Port - 75-120 ohm

2 x Coax - 1 x RJ45 (RJ48)
75 - 120 ohm
Coax - Twisted Pair
G703 and G704 Compliant
E1 (2Mbit/s) and E2 (8Mbit/s)

The Dual Coax to RJ45 (RJ48) G703 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. The G703 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 Adapters are also available for mounting on a 19 inch 1U rack mount Bulkhead Plate.

Tekmos G703 Balun Adapters are manufactured to exacting standards to ensure reliability and are fully compliant with the ITU-T G.703 recommendation for unsurpassed compatibility with E1, T1, E2 and T2 networks.
