Optical Line Protection 1-1
Overview
XH-OLP-M-SA Optical Line Protection module 1-1 is a main fiber and standby optical fiber fault automatic light path switching module, the module monitoring main fiber and standby fiber at the same time, when the main optical fiber power signal is below the set value and standby optical fiber signal is normal, the module automatic switching optical path to standby optical fiber;When for standby optical fibe power signal is below the set value and the main optical fiber signal is normal, the module automatic switching optical path to the main optical fiber;The module supports RS – 232 serial port communication, can be set up by agreement or query module information.
Feratures
- Channel low insertion loss and high stability
- Real-time monitoring of the main optical fiberandstandby optical fiber optical power size.
- Optical fiber main/standby switch automatically.
- Supports RS-232 serial port communication
