Abstract
According to an aspect, a flexible node design for a high-degree ROADM is provided. In an embodiment, this design is implemented as a network node. The network node includes a plurality of optical input and a plurality of optical outputs. The network node further includes a MEMS (or other Optical Cross Connect, OXC) component and a WSS component, where each of the OXC and the WSS component has a set of inputs of the plurality of optical inputs and a set of outputs of the plurality of optical outputs. In some embodiments, the network node has a set of add inputs supported by one or both of the OXC and WSS components. In some embodiments, the network node has a set of drop outputs supported by one or both of the OXC and WSS components.
