ABSTRACT:
An arrayed waveguide grating may include a plurality of waveguides, each associated with a different channel in a wavelength division multiplexed system. Each incoming signal channel in a node of a wavelength division multiplexed network may be of an arbitrary wavelength and is provided to one of the wavelength converters attached on the arrayed waveguide grating. Each converter also receives one of blank light channels of different wavelengths on a grid. The converters convert each of the incoming wavelength signals to one of the distinct new wavelength signals on the grid of wavelengths, and these new wavelength signals are multiplexed into a fiber.
