星形環狀被動式光纖網路之錯誤偵測與自動復原機制

Abstract

在這篇論文中，我們展示並分析一些關於光纖光柵感測網路及擁有全保護機制之星形環狀被動式光纖網路的能力。 在第一個部份，我們討論不同架構下的點對多點技術之光纖光柵感測網路系統。當被動式光纖網路有任何的光纖損傷發生時，這些感測系統會運用光纖光柵和光纖雷射結構去偵測出此連線錯誤的狀況。我們也提出一個簡單的方式可以偵測出網路中的連線錯誤。 在第二個部分，我們提出具有光纖光柵感測系統之星形環狀被動式光纖網路。這個網路架構提供了錯誤偵測與自動復原機制，可以迅速的恢復訊號流量。結合了這些功能，可提昇光纖網路中訊號傳輸的品質還有可靠度，我們對於這個架構的可行性更做了進一步的評估與確認。上述的這些研究，將有助於被動式光纖網路的發展。

In the thesis, we demonstrate and analyze the capability of the fiber Bragg grating sensor networks and star-ring passive optical networks with full protection mechanism. The first part presents and discusses the different architecture of fiber Bragg grating sensor systems for point to multipoint topology. This sensor system applies the FBGs and fiber laser scheme to detect the link fault conditions when any fiber cut occurs in the passive optical networks. We also propose one kind of easy way to detect the link faults in the networks. In the second part, we proposed the star-ring passive optical networks with FBG sensor system. This network architecture implements the fault identification and self-healing function to restore the traffic promptly. By incorporating these functions, the optical network will improve the quality and reliability of data communication. We do the further evaluation and verify the practicability of this architecture. These investigations will be useful in the development of the passive optical networks.
