100G protection scheme
100G Non-coherent transmission
100G Coherence transmission
200G Coherence transmission
Optical channel 1 + 1 protection (OCP)
Protects the entire transmission segment after the combination and division of waves, including optical cables and optical amplifiers
The multiplexing section no-optical signal is used as the criterion to trigger switchover, and when the performance of the active router deteriorates or there is no matte, the system automatically switches to the standby line. Since the APS protocol is not required, the protection switching is stable and fast
For the ring-shaped network scenario
