Optical Line Protection

Product Description:

XH-OLP-1-1- Optical Line Protection module is mainly used in optical fiber transmission to automatically switch the main fiber and backup fiber fault judgment. In the optical network signal link, when the optical signal of the main fiber exceeds the set optical power alarm value (such as the threshold set by the power drop, including no light), the module automatically switches from the main fiber to the optical path of the backup fiber, and vice versa. In the event of a fiber failure, the module automatically switches back to the main fiber (the module detects whether the optical path is normal, and the normal optical path can be automatically switched). The module supports RJ45 Ethernet and serial RS-232 communication, and the status information of the module can be inquired through commands.

Features:

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
