what is E1 g703 balun?

A balun is an electrical device that converts between a balanced signal (two signals working against each other where ground is irrelevant) and an unbalanced signal (a single signal working against ground or pseudo-ground). The origin of the word balun is bal(ance) + un(balance).

E1 balun are passive devices that convert E1 signal between balanced (120ohm RJ48 TP) and unbalanced (75 ohm BNC coax) interface and vice versa. In addition, E1 Balun can provide impedance transformation, thus name E1 Balun as impedance converter.

E1 Balun's Application:

A balun's function is generally to achieve compatibility between systems. They are appllied in data transmission networks device.E1 G.703 impedance balun solve the mismatch between UTP and coaxial cable. They are used to convert an E1 carrier signal from coaxial cable (BNC connector,1.0/2.3 connector,1.6/5.6connector) to UTP CAT-5 cable or IDC connector.The E1 G.703 balun also perform 120 ohm to 75 ohm signal conversion,used as impedance converter.

Depending on the coax connector type and the RJ45 connector, there are several models available:

BNC to RJ45/RJ48 Balun,

1.0/2.3 G.703 E1 Balun adapter,

L9 (1.6/5.6) E1 Balun,

fly-cable to RJ45 E1 Balun,

BNC,1.0/2.3,1.6/5.6 IDC balun,

Depending on the E1 channels, there are several models available:

single port E1 G.703 Balun,

16 ports E1 Balun panel,

24ports E1 balun panel;

These Balun types can meet kinds of customers application requirements.
