An optical wavelength cross connect is provided to receive multiple input optical signals that each have multiple spectral bands and to transmit multiple output optical signals that each have one or more of those spectral bands. The optical wavelength cross connect includes multiple wavelength routing elements, which are optical components that selectively route wavelength components between one optical signal and multiple optical signals in either direction according to a configurable state. As used within the optical wavelength cross connect, each of the wavelength routing elements receives at least one optical signal corresponding to one of the input optical signals. A mapping of the spectral bands to the output optical signals is determined by the states of the wavelength routing elements.
An optical wavelength cross connect for receiving a plurality of input optical signals each having a plurality of spectral bands and transmitting a plurality of output optical signals each having one or more of the spectral bands, the optical wavelength cross connect comprising:
A K×K optical wavelength cross connect for receiving K input optical signals each having a plurality of spectral bands and transmitting K output optical signals each having one or more of the spectral bands, the optical wavelength cross connect comprising an array of interconnected optical wavelength cross connects, at least one of which is smaller than K×K and includes a plurality of wavelength routing elements, each such wavelength routing element adapted for selectively routing wavelength components between a first optical signal and a plurality of second optical signals according to a configurable state of such wavelength routing element, wherein a mapping of the spectral bands comprised be the plurality of input optical signals to the plurality of output optical signals is determined by states of the interconnected optical wavelength cross connects.
A method for distributing a plurality of spectral bands comprised by a plurality of input optical signals onto a plurality of output optical signals, the method comprising:
