Description
These Balun Panels provide 75/120 ohm impedance matching for 16 E1 Circuits, converting unbalanced coax circuits to balanced twisted pair. Coaxial connectors can be specified as BNC or 1.6/5.6 (Small Siemens). Twisted pair connectors are 50 way Female Telco (AMP Champ), which are wired as per the wiring scheme below. Our bespoke section contains details of this Balun Panel wired to Nortel specifications.

Please e-mail us if you require a different wiring scheme.

Designed to meet or exceed ITU-T G.703 Specifications for bi-directional signal conversion, at data rates from 2.048 to 8.448Mbit/s.

When Impedance Matching is not required our 16 x E1 Through Coupler provides a neat standard solution.
