Point-to-point Networking Optical Line Protection

Feb 01, 2023


Schematic diagram of networking





  • The two stations use 2-core optical fiber to build a point-to-point transmission network, which can support the maximum 25.6T transmission capacity (400G * 64 waves), which greatly saves optical fiber resources


  • Ultra-long distance transmission can be realized by configoptical layer units such as BA, LA, PA and DCM (incoherent transmission application)


  • OSC can realize the signal communication of each station, and the whole network can be managed by single station access



Optical line 1 + 1 protection(OLP)




  • Protect the transmission section optical cable


  • The line no-light signal is used as the criterion to trigger the inversion. When the performance of the main line deteriorates or there is no light, the system automatically changes to the standby line. Since the APS protocol is not required, the protection exchange is stable and fast


  • Often used in point-to-point and low-protection scenarios
