We propose a new hierarchical optical cross-connect node architecture that utilizes 3D MEMS-based WSS and WBSS (Waveband Selective Switch). 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.
