Abstract
This reasercah presents a switching architecture for any large port number mirror type optical switch. We show the switching arrangement and the construction process to realize mirror type optical switches. The proposed architecture refers to the Waksman network. Compared to other switching architectures, this architecture uses a minimum number of mirrors. Six setps of the mirror arrangement method are proposed to assist building up a large port number mirror type optical switch in an efficient way. By the analysis of all loss sources, the design parameters of the mirror are identified. The generalized simulation results show, that the optical switch architecture of this work is capable to archive the BELLCORE specification requirements for low and high port numbers. Finally, the 4x4 and 8x8 optical switchs have been fabricate and the experimental results show that insertion losses, switching time and long-cycle test all meet the BELLCORE 1073 specification requirements.
