使用光迴路之高速長距離波長多工光固子傳輸系統

Abstract

近幾年來，光纖通訊系統對於高傳輸速率和高傳輸量的需求日漸龐大。而光固子非常適合用於高速長距離傳輸，且利用波長多工的技術可以大大地增加整個系統的傳輸量；此外，色散補償在波長多工光固子傳輸系統中佔著舉足輕重的地位。在本篇論文裡，我們利用一個新穎的色散斜度補償器去針對不同波長的信號作色散補償。 我們也架設了一個光迴路的實驗平台，對於長距離傳輸的研究與發展非常有益。在實驗架構中，每50公里的光纖放置一台摻鉺光纖放大器，而在系統中傳輸的位元率是30-Gb/s。最後整個實驗的結果會利用位元錯誤率的測量、眼圖和光譜而展現。

The demand for the ultralarge capacity and ultrahigh-speed fiber transmission systems is becoming larger in recent years. Optical soliton is suitable in ultralong-haul and high-speed transmission system. Aggregate system capacity has been dramatically increasing by using the wavelength division multiplexing (WDM) transmission technologies. Dispersion management plays an important role in WDM soliton transmission. In this thesis, we use a novel dispersion slope compensator for the problem of dispersion slope in WDM system. We set up an experimental platform of circulating loop, which is useful for the research and development of long-haul transmission. This experiment is performed with 50-km amplifier spacing, operating 30-Gb/s. Experimental performance is represented by BER, eye and data patterns, and optical spectrum.
