Abstract

In the P-OTS, OTN line signal of the OTN line card contains packet signals within ODU frame. To protect an ODU path, an ODUk path protection function is required. The proposed ODUk linear protection function is implemented based on the hardware within the OTN line card. We presented the operation of 1+1 unidirectional ODUk SNC protection switching. The measured protection time is less than 13ms.
