ABSTRACT:
Hierarchical hybrid optical networking is based on balancing cost and performance of optical networks by providing transparent (optical) switching of subsets of wavelengths in addition to opaque (electrical) switching of individual light paths. Effective use of wavelength-subset switching requires aggregating and deaggregating wavelength subsets in a simple, cost-effective manner. Non-uniform wavebands are introduced and analyzed their performance advantage as compared with uniform wavebands. Also proposed are several architectural options for a hierarchical hybrid optical cross-connect system that combines non-uniform wavebands and improved utilization of OEO ports.
