Abstract: This article provides a detailed introduction to VC-OTN technology. Based on the characteristics and technological advantages of VC-OTN, a SDH network transformation scheme based on VC-OTN is proposed. This scheme can synchronously achieve the network evolution goals of wide area coverage of OTN networks and the overall withdrawal of SDH core aggregation layers, and has certain practical value.
