Abstract
An optical node includes a reconfigurable optical add drop multiplexer (ROADM) core configured to transmit optical signals of multiple wavelengths to and receive optical signals of multiple wavelengths from another optical node. The ROADM core is also configured to add optical signals thereto and to drop optical signals therefrom. The node also includes two different types of add-on devices, each connected to the ROADM core device and configured to process optical signals of multiple wavelengths. As a result, a multifunctional and reconfigurable optical node can be provided.
