本文共計採用「單模光纖(Single Mode Fiber；SMF)」、「色散補償模組(Dispersion Compensation Module；DCM)」以及「大有效面積光纖(Large Effective Area Fiber；LEAF)」組成不同光路配置，在100Km的傳輸距離上進行「拉曼放大」實驗，其間並就各種不同光路配置之色散抑低/補償與調動泵激功率高低作增益平坦處理之成效進行比較探討。
針對本文中心議題–「有效降低“多泵激架構”FRA製作成本」，在拉曼放大頻段不變的前提下，我們提出以“高功率少波長泵激”取代現行所採用“低功率多波長泵激”配置，經實驗結果驗證此一構思確屬可行–不僅在確保“Raman增益/放大頻帶”不變的條件下，成功地拉寬二泵激之配置間隔長達40nm，減少使用一顆泵激雷射，而且毋需大幅度調動泵激功率的情況下即可達到

In this thesis, the problems of design and implementation of a fiber Raman amplifier (FRA) based on backward-bipump architecture is investigated. In addition, the characteristics of the proposed FRA are analyzed. Three kinds of devices, i.e., single mode fiber (SMF), dispersion compensation module (DCM), and large effective area fiber (LEAF), are employed to evaluate the effect of Raman amplification over an 100Km transmission distance. Experimental results indicate that the suppression and compensation of dispersion are not only capable of enhancing the Raman gain but also helpful for the gain-flattened process using pump power control. As suggested in this thesis, a high-power and wide-space pump’s scheme is one of the possible solutions for achieving high Raman gain while maintaining excellent flatness.
