Abstract
A method for a scalable Reconfigurable Optical-Add Drop Multiplexer (ROADM) includes determining a plurality of channels at a ROADM node in an optical network will ingress and egress at another ROADM node in the optical network, such that the plurality of channels are able to share a same physical routing in the optical network; interfacing the plurality of channels at a degree in the ROADM node, such that the plurality of channels are connected to the another ROADM node in the optical network; adding and dropping the plurality of channels at the ROADM node with corresponding modems; and pre-combining the plurality of channels onto a common port between the degree and the corresponding modems, such that the plurality of channels connect to the degree together in a single connection. An add/channel count of the ROADM node is higher with the pre-combining.
