Abstract:
A method for synchronous cross-connect switching in optical transport network, the method includes: receiving optical channel transport unit (OTU) signals; mapping the OTU signals into interim switching units, wherein the interim switching units match bit rates of the received OTU signals; performing a synchronous cross-connect switching for the interim switching units; and demapping the interim switching units obtained after the synchronous cross-connect switching to obtain the OTU signals.
