    摘要: 本文旨在於所提出基於可重組光放大器之分波多工-被動光網路方案的探討。詳細地探討所提的可重組光放大器於分波多工-被動光網路系統中作為光放大器單元所提供保護機制之運作方式。所提出的設計能夠滿足光線路終端(Optical Line Terminal)光放大器單元作為上行和下行光放大器及光放大器保護的需求。
    可重組光放大器類型三是三種類型中主要的研究重點；在可重組光放大器類型一及類型二正常操作下，其類型三提供雙向光路旁路。此外，基於摻鉺光纖放大器(Erbium Doped Fiber Amplifier)結構，它提供可切換至前向泵激或後向泵激，以符合上行及下行光放大器的備用光放大器之要求。
    在實驗中，可重組光放大器類型三是由一自製控制電路來控制，使其能夠自動地偵測其他可重組光放大器的狀態與切換它所需的狀態。實驗結果證實放大方向切換的延遲時間約0.82 ms是優於先前研究結果的4.4 ms，其延遲時間也大幅地降低許多。
    This thesis aims at the discussion on the proposed wavelength-division-multiplexed passive optical network (WDM-PON) scheme based on reconfigurable optical amplifiers (ROAs). There are many detailed descriptions of the proposed ROAs in the WDM-PON system for the optical amplifier unit offering the protection operations. The proposed design can meet the protection requirement of the uplink and downlink optical amplifiers built in the optical amplifier unit at the optical line terminal.
    ROA3 is the most significant study of three types of ROAs. It provides the bidirectional optical bypass paths when ROA1 and ROA2 work normally. Additionally, based on the architecture of Erbium-Doped Fiber Amplifier, it can also operate at either forward pumping or backward pumping to meet the requirement of the spare optical amplifier for protecting the uplink and downlink optical amplifiers.
    In the experiments, the ROA3 controlled by a self-made circuit has the ability of automatic detecting the status of other ROAs and switching to the corresponding operation state. The experimental results show that the delay time about 0.82 ms for amplifying direction switch is superior to the prior research result of 4.4 ms and dramatically decreases a lot.
