Abstract
A protected optical switch matrix having N inputs and N outputs and including an optical switching fabric (S2-S2'), an input interface (S1) performing wavelength conversion and an output interface (S3) performing wavelength filtering. The input interface (S1) and the output interface (S3) are protected by redundancy provided by r redundant units for E working units where r is a number very much less than E.
