Features

The device features integrated circuits based on proprietary intellectual property rights.

It uses modular wide-dynamic range optical detectors.

The device includes one PCM digital business telephone. (optional)

E1 interfaces comply with G.703 recommendations and employ full digital clock recovery and smooth phase-locked loop technology.

When the optical signal is lost, it can detect whether 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.

It provides a remote interface loopback function.

The transmission distance is up to 2-120Km 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.
