16E1 PDH Fiber Multiplexer

The device offers 16 E1 interfaces and the option to include a digital business telephone, making it highly flexible for various applications. It has comprehensive alarm functions and ensures stable and reliable operation. With low power consumption, high integration, and a compact size, it provides an efficient solution.

● 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.
