Discription

Impedance converter is essential connecting hardwork for signal transmission matching between two different transmissions mediun.In the application of G.703,these two kinds of transmission medium are 75ohm unbalanced coaxial cable and 100ohm balanced twisted-pair.Balance means that two channels transmit signal in different ways.Unbalancede means that a channel is grounding and the other transmits signal.Impedance converter makes BNC and RJ-45 physical interface achieve matched junction internally.

Characteristic

1.The impedance convension and matching of 75ohm imbalance signal and100ohm balance signal

2.BNC is used in connection of 75ohm coaxial cable in order to provide two receive(rx)and transit(TX)

3.RJ45is used in connection of 100ohm twisted pair wire

4.Two-way signal convension no additional power supply is needed

5.The 1st and 2nd core of RJ-45interface of 120ohm balance signal communication with one BNC base .the direction of receive(RX) and transit(TX) can be selected freely.
