Q: How to configure Huawei OSN2500 product multiplexed segment ring shared optical path?

A: Take two 2.5G multiplexed segment rings sharing 10G optical fiber as an example, which is equivalent to splitting a 10G optical fiber into two 2.5G optical fibers. For the 10G optical interface board, some of the channels can be mapped to protection group 1 and others to protection group 2, thus splitting a 10G line veneer into two 2.5G line veneers.

Note the virtual splitting of 10G optical ports: 1 to 16 vc4 are virtualized as one 2.5G channel; 17 to 32 vc4 are virtualized as another 2.5G channel. 33 to 64 are protected channels, which can only be allocated for additional services. For detailed configuration methods, please refer to the document "Multiplexing Segment Downward Shift and Multiplexing Segment Shared Optical Path".
