Here, the STM-64 ring of the OptiX OSN 9500 also can be configured as ring with chain SNCP. The switching time is less than 50 ms.

3.  Ethernet Service Protection Configuration

The protection can be implemented at the SDH layer or data service layer. On the data service layer, users can configure the protection according to their requirement. For details, refer to OptiX OSN 9500 Intelligent Optical Switching System  Service Configuration Guide.

There is STM-64 service between NE1 and city 1 (500 km away), use a JL64 to connect the DWDM equipment and city 1.

NE1 configures two more JL64 boards because it needs two STM-64 optical interfaces to form an STM-64 ring. According to the feature of the OptiX OSN 9500, the JL64 connects to NE2 uses Le-64.2 optical module, the JL64 connects to NE4 uses S-64.2b optical module.
