Abstract
A modular optical add/drop system supporting a Colorless, Directionless, and Contentionless (CDC) architecture includes a first Contentionless Wavelength Selective Switch (CWSS)-based optical add/drop device; and one or more channel pre-combiners each having a common port with a transmit port and a receiver port, at least two local add/drop ports, components configured to combine channels between the at least two local add/drop ports and the common port, and a splitter and a combiner connected to the common port, wherein a first output of the splitter and the combiner is connected to the first CWSS-based optical add/drop device. The modular optical add/drop system can further include a second CWSS-based optical add/drop device, wherein a second output of the splitter and the combiner is connected to the second CWSS-based optical add/drop device.
