Abstract
A colorless, reconfigurable, optical add-drop multiplexer (a colorless ROADM) is disclosed. The ROADM may include a de-interleaver, a diffraction grating, and a lens. The de-interleaver may separate an input signal into a first output signal, comprising odd channels, and a second output signal, comprising even channels. The diffraction grating may receive the first and second output signals from the de-interleaver. The diffraction grating may separate each of the first and second output signals into individual channels. The lens may collimate the individual channels received from the diffraction grating.
