OTN Protect OLP 1+3 《20ms Dwdm 400G

The main function of OLP optical protection board is to assist the wave division system to complete the optical line 1 + 3 protection and optical wavelength 1 + 3 protection, which can monitor the main and standby routing optical signal status in real time. Once the optical signal interruption or performance deterioration occurs, it can automatically change safely in the main and standby routes to ensure the rapid recovery of the system; OLP technology is to complete the routing switching operation in the optical layer. Optical layer protection has the incomparable advantages of upper business protection, which is the best solution for users with non-blocking communication.
