XH-OLP-1-1-M optical protection module is mainly used in optical fiber transmission, the main fiber and the backup fiber fault judgment automatic switching. In the optical network signal link, when the main fiber optical signal exceeds the set optical power alarm value (such as power down the set threshold value, including no light), the module automatically switches from the main fiber to the backup fiber optical path, and vice versa when the backup fiber fails to break the fiber, the module automatically switches back to the main fiber (the module detects whether the optical path is normal, and only normal optical path can be automatically switched). The module supports RJ45 Ethernet and serial RS-232 communication, and the module status information can be queried by command.


●With low insertion loss and high reliability

●Real-time monitoring of the status of the main and standby fiber optic signals

●The optical path can be switched manually and automatically

●Support Ethernet and serial communication control
