Fault tolerance determines reliability of local, wide, and metropolitan area networks. Carried- out considerations are addressed to reliability evaluation of the classical, and the enhanced performance double rings, which are configurated according to ShuffleNet interconnection pattern realized by the use of wavelengths dependent signals. The considered multi-channel optical networks are modeled applying the Queuing Theory: the Continuous Time Markov Chains. Introduced models allow to determine in the data networks Mean Time to Failure, Data Throughput, and Time Delay. The results are implemented for performance simulation of advanced fiber optic data networks oriented towards High Speed Data Communications.
