On the analysis of optical cross-connects with limited wavelength conversion capability

A limited-wavelength-interchangeable cross-connect (L-WIXC) is considered in this paper. While a (fully) wavelength-interchangeable cross-connect (WIXC) is functionally equivalent to a conventional switching matrix, the modeling of L-WIXC will differ from that of WIXC due to limitations in the wavelength interchange capability. We propose an analytical model for describing the connection setup in various L-WIXCs. Two methods for evaluating the blocking performances of L-WIXCs based on this model are introduced and applied for the analysis of four classes of L-WIXC
