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

It utilizes modular wide dynamic range optical detectors.

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

The device optionally includes one PCM digital business telephone.

It can detect when the optical signal is lost, indicating either power failure or fiber interruption at the remote end, and provides alarm indications.

It has the capability to view and display the working status of the remote equipment at the local end.

It offers a remote interface loopback function, facilitating line maintenance.

The non-relay transmission distance can reach 2-120 kilometers.

Multiple power supply options are available, including AC220V and DC-48V/DC24V.

The DC-48V/DC24V power supply has an automatic polarity detection feature, eliminating the need to differentiate between positive and negative polarity during installation.
