According to one embodiment, an interconnect switch has an optical switch fabric (OSF) having N input ports and N output ports. The OSF has a bank of optically interconnected wavelength-selective switches and is adapted to route optical signals from the input ports to the output ports. In a fully deployed implementation, the interconnect switch has N input line cards and N output line cards. Each of the input line cards is adapted to generate N respective modulated optical signals using carrier wavelengths that are controllably selected from more than N carrier wavelengths to provide wavelength redundancy for optically connecting the input line card and any of the output line cards. In a partially deployed implementation, the interconnect switch has fewer than N input line cards and/or fewer than N output line cards. In either the fully deployed implementation or a partially deployed implementation, the interconnect switch is capable of load balancing.
