Optical Protection
OLP is a optical wavelength/line protection board, its main function is to perform a real-time monitoring on the state of the signals in the main and standby fiber core optical path. In the event that the fiber core is blocked or degraded in performance, it can implement the secure rearrangement automatically in the main and standby fiber core, so as to guarantee optical signals in the system line to recover quickly.
OLP technology is to complete the routing switch operation in optical layer. The optical layer protection has the incomparable advantages over the protection of upper services, and it is the best solution to provide the user with an uninterrupted communication.
