The device features a modular wide dynamic range optical detector.

Uses standard 2 wire telephone(non-telephone handles) set as engineering order-wire hotline (optional).

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

This device is capable of detecting power outage or fiber break at the opposite end when the optical signal is lost, and indicating the alarm through LED lights.

It can display the working status of the remote device at the local end.

This device provides a remote interface loopback function for line maintenance.

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

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