Abstract
由於高密度多波長工分工器（DWDM）及窄波寬雷射二極體技術的開發解決了近年來因資訊快速成長而網路頻寬不足的問題。目前以鍍膜方式所做成的薄膜干涉濾鏡為基礎的DWDM元件最具穩定性及最適合量產，也最受市場歡迎。本文利用光波長加入╱取出多工器（WADM）加上2x1光開關組成一雙向性WADM，此裝置具有當網路鏈路故障時能即時的回復傳輸功能。最後我們設計一嶄新的三階層高密度多波長分工╱次載波多工（DWDM╱SCM）星形－巴士－環形網路架構，此架構具有高穩定性，大傳輸容量及頻寬，自動故障回復等功能，符合未來高速、寬頻網路之需求。
Owing to the development of dense wavelengh division multiplexing (DWDM) and narrow-band DFB laser, the problem of network bandwidth can be solved in late year. Currently, multi-layer thin interference filter is the base of DWDM component. This component can provide the high stability, suitable large production and marketing. In this paper, we use wavelength add/drop multiplexing (WADM) with 2x1 optical switch composed into a bidirectional WADM (B-WADM). If any link fails, B-WADM can perform self-healing function automatically. Moreover, we design a novel three-level star-bus-ring architecture for DWDM/SCM passive optical networks. The SBRA can provide high-capacity, reliable and flexible structure for future broadband networks.
