Description
These Balun Adaptors provide a low cost solution for connecting from a balanced twisted pair interface to an unbalanced coax one.
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.
