We evaluate the total number of MEMS mirrors necessary to implement the node, a key parameter in determining node reliability and cost. It is demonstrated that the proposed hierarchical architecture requires a lot less mirrors than conventional single-layer WSS based node architectures.}, pages = {1--2}, title = {Hierarchical Optical Path Cross-Connect Node Architecture Using WSS/WBSS}, year = {2008} }
