8E1 PDH Multiplexer

The 8E1 PDH Optical Multiplexer supports 1-8 channel E1 transmission with an optional digital engineering order-wire. Designed for reliability, this compact device features low power consumption, high integration, and real-time alarm monitoring, making it an ideal solution for flexible point-to-point fiber optic networking.

The device provides 1 to 4 E1 interfaces and an optional 1-channel digital engineering order-wire (EOW), offering extremely flexible application configuration.

The equipment features comprehensive alarm functionality, ensuring stable and reliable operation. It is characterized by low power consumption, high integration, and compact size.

1. Based on proprietary intellectual property high-performance integrated circuits.
2. Employs a modular wide-dynamic-range optical detector to ensure signal sensitivity and stability.
3. Supports 1-channel PCM digital engineering order-wire (EOW) for convenient site maintenance (Optional).
4. Fully complies with ITU-T G.703 recommendations, featuring built-in all-digital clock recovery and smooth phase-locked loop (PLL) technology.
5. Automatically detects whether optical signal loss is due to remote equipment power-off or a fiber fault, with LED indicators for alarm status.
6. Supports monitoring the operating status of the remote equipment from the local terminal.
7. Supports command-based remote interface loopback, facilitating efficient line commissioning and troubleshooting.
8. Supports a non-relay transmission distance ranging from 2km to 120km.
9. Offers multiple power supply modes, including AC220V, DC-48V, or DC+24V.
10. Features automatic polarity detection (Polarity-Free) for DC-48V/DC24V inputs, eliminating the need to distinguish polarity during installation.
