can anyone explain how DWDM and SDH integrate?

I’ve trawled through wikipedia etc can’t seem to get a simple explanation. I understand SDH (SONET in USA) and DWDM but can’t figure out how one talks to the other.

All help appreciated- many thanks

WDM technologies provide an overlay layer for the SDH network. Meaning, you can use OADM (optical add-drop multiplexers) to interconnect SDH nodes even with DWDM interfaces. They can however interwork on the controll plane, in that case GMPLS protocol is being used for the interworking. On the data plane, there is no interworking – WDM is a transport layer for SDH. See wikipedia for more.
