Light channel 1 + 1 protection（OCP）

• Protect the whole transmission section, including optical cable and optical discharge

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

• Often used in circular network scenarios
