This device features a modular wide dynamic range optical detector.

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

It is able to detect power outage or fiber break at the opposite end when the optical signal is lost, and indicate the alarm through LED lights.

It has a function to display the working status of the remote device at the local end.

A remote interface loopback function is provided on this device for line maintenance.

The transmission distance is up to 2-120Km without a relay.

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