BIC-C1 is a Dual Coax to RJ45 Balun Adapter which realize 75 Ohm coax to 120 Ohm RJ45 impedance converter.


G.703 impedance matching baluns solve the mismatch between UTP and coaxial cable. The baluns can be used for internal network connectivity T1/E1/CPE network transmission equipment and other applications.

Supporting E1 data rates to 2.048 Mbps, the BIC-C1 receives 75 ohm signals and converts them to 120 ohm for transmission over a network or reception by a CPE. The signals output by the BIC-C1 are scaled to match the pulse shape requirements specified by the CCITT G.703 standard. The BIC-C1 can perform 120 ohm to 75 ohm signal conversion as well, giving the device a dual role.
