G.703 E1/T1 and E2/T2 Coax to RJ45 Dual Fly-Lead Balun Adaptors/Adapters

Double BNC Plug (6" Cable) to RJ45 Shielded Jack

Double BNC Plug (6" Cable) to RJ45 Shielded Jack

Description
These Transmit and Receive Balun Adapters provide a low cost solution for connecting a balanced 120 ohm twisted pair interface to an unbalanced 75 ohm coax network, or, vise versa. 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.
