Assumed network architecture. Each DWDM link carries up to (e.g.) 80 wavelengths and is routed over a fiber layer (not shown). The IP/OTN and OTN/ROADM layer interfaces are OTN formatted and (today) normally bidirectional with symmetric capacity. The IP links are unidirectional. We consider architectures where the routers are connected either to the OTN layer or directly to the ROADM layer.
