16E1 PDH Optical Terminal Equipment
Product Overview
This series of PDH optical multiplexers is a point-to-point optical transmission equipment developed based on our proprietary, application-specific integrated circuits (ASICs) for PDH fiber optic transmission. The equipment provides 1 to 8 E1 interfaces (75-ohm); one main and one backup optical port; one orderwire channel; 4 Ethernet interfaces (optional); one expansion interface (configurable for RS232/RS485/RS422/Manchester code, optional); and one Console port (optional). It offers high application flexibility, comprehensive alarm functions, and features stable and reliable operation, low power consumption, high integration, and a compact size.
Key Features
1. Based on proprietary, self-developed integrated circuits.
2. Modular optical receiver with wide dynamic range.
3. Equipped with main and backup optical interfaces, ensuring non-stop operation through dual fiber redundancy.
4. E1 interfaces comply with ITU-T G.703 recommendations, utilizing fully digital clock recovery and smooth phase-locking technology.
5. 4 Ethernet interfaces (optional).
6. One expansion interface (configurable for RS232/RS485/RS422/Manchester code, optional).
7. One Console port (optional).
8. Detects whether a loss of optical signal is due to remote equipment power failure or a fiber break, with LED indicator for alarm.
9. Features local monitoring and display of remote equipment status.
10. Provides remote loopback testing via command interface for ease of line maintenance.
11. Supports a non-regenerated transmission distance of 2 to 120 kilometers.
12. Multiple optional power supplies: AC220V, DC -48V / DC +24V, etc.
13. DC -48V / DC +24V power inputs feature automatic polarity detection, eliminating the need for correct polarity identification during installation.
