Why we need E1 balun?

1. interface converter

Many PDH device have only one kind interface,75ohm BNC coax or 120ohm RJ45 (also called R48). We often need different interface in application field, so we need to convert the interface from 75ohm coax to 120ohm RJ45, or converter from 120ohm RJ45 to 75ohm coax. The E1 balun is the ideal device to resolve the mismatch problem.The E1 balun can converter the interface between 75ohm (coax port) and 120ohm (RJ45 port).The E1 balun’s volume is small and need not power, it is very convenient for the converter application.

2. improve the E1 signal quality

The E1 balun can suppress the noise in E1 signal and improve signal quality, making the E1 signal can transmit longer distance in cable.The E1 g.703 balun can resolve the interface mismatch problem and improve the signal quality.

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
