Abstract:
A reconfigurable optical add-drop multiplexer (ROADM) transport network comprising a plurality of optical fan-out devices and a first plurality and a second plurality of demultiplexers for locally dropping selected wavelengths; and first plurality and a second plurality of multiplexers for locally adding selected wavelengths, the first and second plurality disposed in a cascaded relationship to enable selective coupling between network degrees.
