Crosstalk performance of a wavelength selective cross-connect mesh topology

Summary form only given. Wavelength-domain simulation is used to study the accumulation of common-channel crosstalk (or intraband crosstalk) in a mesh of wavelength selective cross-connects (WSXCs) and wavelength add/drop multiplexers (WADMs). Common-channel crosstalk is generated when signals of the same nominal wavelength interfere at the receiver. Multipath-homodyne crosstalk is the common-channel crosstalk that is generated from either the MUX/DMUX pairs or the switching fabrics when signals from the same source interfere at the receiver. Adjacent-channel crosstalk is rather small and is thus neglected.
