Description
These Transmit and Receive Balun Adaptors provide a low cost solution for connecting a balanced 120 ohm twisted pair interface to an unbalanced 75 ohm coax network. The Balun Adaptors provide isolation protection and impedance matching, enabling 75 ohm coaxial networks to interface with 120 ohm twisted pair equipment, bi-directionally, matching signal impedance and pulse shapes in accordance with the G.703 standard. Suitable for 2-8Mbit/s E1/T1 and E2/T2 data streams.
