Abstract:
An optical cross-connect node includes a first optical switching switch, a second optical switching switch, a wave-dropping wavelength switching switch, a wave-adding wavelength switching switch, and a pass-through dimension switching switch. The first optical switching switch receives an optical signal, where the optical signal includes a first optical signal and/or a second optical signal. The first optical switching switch sends the first optical signal to the wave-dropping wavelength switching switch. The first optical switching switch sends the second optical signal to the pass-through dimension switching switch. The wave-dropping wavelength switching switch performs wavelength switching on the first optical signal. The wave-adding wavelength switching switch performs wavelength switching on a third optical signal generated locally and sends it to the second optical switching switch. The pass-through dimension switching switch performs dimension switching on the second optical signal and sends, to the second optical switching switch, the second optical signal that has undergone dimension switching.
