摘要

本論文透過結合不同領域之交換網路理論概念，透過隨意維克士曼之網路架構，將其應用於反射式光開關的鏡面排列架構，其目的主要是大幅降低傳統交錯式鏡面排列所需的切換機構數量，同時還突破以往多層架構式光開關，只能應用於2的冪次的限制。其次，此鏡面式光開關架構，分析可能產生之各種光功率損失來源，提出設計時所需要考量的各種要點，同時驗證所提出架構的可行性。最後，透過4x4與8x8光開關的研製，提出光開關的設計、組裝系統與鏡面對位方法。藉由影像光路系統與紅外線感應卡設計一組裝規則，提升整體對位的速度。另外對於4x4與8x8光開關，各自提出一組裝對位順序，確保光開關的組裝精度。在組裝後，對於4x4與8x8光開關進行光損失值之量測。量測之結果通過Bellcore 1073測試規範及長時間可靠度之要求。

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.
