    Description 

    OLP-Optical Line Protection is a device that is used in the protection of network transmission line, it can realize optical power monitoring and automatic switching. In optical communication network, OLP constantly monitors optical power of working optical fiber and standby optical fiber. When the optical power value of working optical fiber is below the set switching threshold, the system raise the alarm prompt and switches to standby fiber automatically, which achieve line protection of optical transmission system.

    GEZHI provides 3 types of line protection: 1:1 line protection, 1+1 line protection and 1-1 line protection . Wavelengths and connectors can be customized to meet special control and applications.
