Abstract: Adopting multi-granularity switching in WDM optical networks can dramatically reduce the size of optical cross-connect, which saves the cost of building and maintaining of networks. In this paper, the structures of multi-granularity optical cross-connect in some previous works are introduced, and two kinds structure of multi-granularity optical cross-connect are proposed. The performances of different structures are analyzed and compared in terms of size of switching box, switching and grooming abilities, and the blocking performance.
