BL-703 Balun G.703 75-ohm to 120-ohm Female BNC to RJ-45 – Model: BL-703

BL-703

Description of Product

BL–703 Balun Converter solve the problem such as unmatchable between the Impedance of twist pair devices with 75 ohms to 120 ohms and physical interface etc. As the E1 intercommunication usuallyunmatched because of the products offered by different communication device manufacturers, it makes the device use in large amount. It can support E1 data rate 2.048Mbps,and realize the transport transparent between 75ohm and 120 ohm.The output sign according CCITTG.703 .
