Abstract
Bidirectional wavelength cross connects include a plurality of ports, each configured to receive an input optical signals, each input optical signal having a plurality of spectral bands. At least one of the plurality of ports is disposed to simultaneously transmit an output optical signal having at least one of the spectral bands. A plurality of wavelength routing elements are configured to selectively route input optical signal spectral bands to output optical signals.
