The 77-OSW series is a high-performance optical automatic switching module designed for optical fiber communication, CATV broadcasting, and telecom transmission systems. It provides reliable optical path switching, automatic line protection, and real-time optical power monitoring to ensure uninterrupted transmission of optical signals.

Adopting high-performance optical switching components, this product features ultra-low insertion loss, high return loss, and long service life. It supports both automatic and manual switching modes, and the switching threshold can be flexibly set according to on-site requirements. Equipped with a dot-matrix LCD screen, it displays real-time input optical power and working status, while LED indicators clearly show the equipment operating state.

The 77-OSW adopts a standard 19-inch 1U rack-mount structure for easy integration into standard equipment rooms. It supports hot-swappable dual power supply (AC/DC optional) to ensure high system reliability. Through the RJ45 network management interface, users can realize local and remote monitoring, control, and status query via SNMP protocol, greatly improving the intelligence and maintainability of optical network systems.
