Abstract :
We present a wavelength-selective cross-connect (XC) switch architecture interconnecting multiwavelength self-healing rings (SHRs). It preserves the fault protection and routing properties used in the WDM SHRs while keeping the process completely transparent. The main component of any XC that interconnects any two SHRs was found to be a 3×3 switch. A unique architecture and transition algorithm for this switch was developed using 2×2 switches in a wide-sense nonblocking configuration and a design incorporating multiwavelength 2×2 switches was presented
