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

A range of compact dual coax Balun Adapters suitable for mounting on a Bulkhead Panel - can also be used as standalone baluns. Designed for connecting a balanced 120 ohm 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.

Can be used as a standalone device or up to 16 Balun Adapters can be installed in a Mounting Plate.
