8 Channels E1 to Fiber Converter 8 Channels E1 to Fiber Converter


Based on self-copyright IC

Modular wide dynamic optical detector

E1 interface complies with G.703, adopts digital clock recovery and smooth phase-lock technology

When the optical signal is lost, it can detect the remote device is powered off or the fiber is disconnected, and indicates an alarm by LED

The local device can view the remote device’s working condition

Provide command the remote interface Loop Back, ease line maintenance

The transmission distance is up to 2-100Km without interruption

AC 220V, DC-48V, DC+24V can be optional

DC-48V/DC+24V power supply with automatic polarity detection function, when installed without distinction between positive and negative
