Title:
OPTICAL CROSS-CONNECT NODE AND OPTICAL SIGNAL EXCHANGE METHOD
Document Type and Number:
WIPO Patent Application WO/2016/165053
Kind Code:
A1
Abstract:
Disclosed are an optical cross-connect node (300) and an optical signal exchange method. The optical cross-connect node (300) comprises: a first optical switching switch (301), a second optical switching switch (302), a lower-wave wavelength exchange switch (303), an upper-wave wavelength exchange switch (304) and a punch-through dimension exchange switch (305), wherein the first optical switching switch (301) receives an optical signal, with the optical signal comprising a first optical signal and/or a second optical signal, sends the first optical signal to the lower-wave wavelength exchange switch (303) and sends the second optical signal to the punch-through dimension exchange switch (305); the lower-wave wavelength exchange switch (303) performs wavelength exchange on the first optical signal; the upper-wave wavelength exchange switch (304) performs wavelength exchange on a third optical signal generated locally, and sends the third optical signal subjected to wavelength exchange to the second optical switching switch (302); and the punch-through dimension exchange switch (305) performs dimension exchange on the second optical signal and sends same to the second optical switching switch (302). The optical cross-connect node (300) avoids the case where upper and lower waves share an optical switch for wavelength exchange, and can reduce the crosstalk of the optical cross-connect node (300).
