A balun is a type of electrical transformer that can convert electrical signals that are balanced to signals that are unbalanced and vice versa. They are also used to change impedance of twisted pair's 120 ohm to coaxial's 75 ohm. An E1 balun's function is generally to convert an E1 carrier signal from coaxial cable to UTP CAT-5 cable.

The BLN4010 is miniature Baluns designed for applications where space is restricted due to small dimensions or high densities. The fully shielded design intended for panel mounting and IDC twisted pair termination are available in either standard BNC or 1.6/5.6 jack unbalanced connectors.
The BP20 G.703 Balun Patch Panel matches multiple sets of dual 75 ohm coax connections to multiple 120 ohm twisted pair connections. Supporting data stream to three speed rates, 2-8 Mbps for E1/T1 and E2/T2, 2-8-34 Mbps for E1/T1 to E3, 34 to 155 Mbps for E3 and higher, the patch panel bi-directionally match, not only signal impedance, but also the pulse shapes of the signals according to the CCITT G.703 standard. The modular construction allows up to 16 separate G.703 Balun Modules in a 19" rack mountable chassis. This modular provides a cost-effective solution and can be purchased separately.
