The main function of the optical protection card (OLP) launched by Sintai Communication is to assist the WDM system to complete optical layer protection solutions such as optical line 1+1 protection, optical wavelength 1+1 protection. etc.. It can monitor the optical signal status of the main and standby routes in real time. Once the optical signal is interrupted or the performance is degraded, it can automatically make a safe switch on the main and standby routes to ensure the rapid recovery of the optical signal of the system. OLP technology is to complete the route switching operation in the optical layer. Optical layer protection has incomparable advantages over upper layer service protection, and is the best solution to provide users with non-blocking communication.
