Product Description

1260~1650nm Optical Line Protection Module with RS-232 Serial Port

The GZ-OLP-M-LP optical fiber protection module provides automatic light path switching between main and standby optical fibers. This module continuously monitors both fiber paths and automatically switches to the standby fiber when the main fiber signal drops below the set threshold, or back to the main fiber when the standby signal fails. Supports RS-232 serial port communication for configuration and status monitoring.

Key Features

Low insertion loss with high stability
Real-time monitoring of main and standby optical power levels
Automatic main/standby fiber switching
RS-232 serial port communication support
