摘要

本篇論文首先研究利用摻鉺光纖放大器（EDFA），搭配單模光纖（SMF）與色散補償光纖（DCF）組合的光通信系統，來分析非歸零（Non-return to Zero；NRZ）碼、歸零（Return to Zero；RZ）碼、載波抑制歸零（Carrier-Suppressed Return-to-Zero；CSRZ）碼等3種編碼，並以16組通道，傳輸10Gbit/s速率於C-band，設計一DWDM傳輸架構，且以60公里為一個傳輸區段（Span）的系統上，達成傳輸26個區段(1560公里)並且誤碼率（BER）低於10的負6次方，Q值大於6的長距離傳輸的要求。
另外，研究以摻鉺光纖放大器及拉曼放大器串接成混合式光放大器，同樣搭配單模光纖（SMF）與色散補償光纖（DCF），所組合成的光通信系統，應用新型的調變格式-載波抑制歸零差動相位偏移鍵制（CSRZ-DPSK）碼，並以32組通道，傳輸10Gbit/s速率於C-band，設計一DWDM傳輸架構，且以120公里為一個傳輸區段（Span）的系統上，成功達到傳輸26個區段(3120公里)並且誤碼率（BER）低於10的負6次方，Q值大於6的超長距離傳輸的要求。
未來光纖通訊將走向長距離及高傳輸速率的趨勢，在此以基本的單模光纖傳輸架構，減少變動現有系統情況下增加傳輸距離；希望本論文內容能提供學術研究及光纖通訊產業作為參考並發展更遠距離、更多傳輸通道的光纖通訊系統。

The thesis first studies the optical communication system using the Erbium-Doped Fiber Amplifier (EDFA) to combine with Single Mode Fiber (SMF) and Dispersion Compensation Fiber (DCF) ,and then analyzes the Non-return to Zero（NRZ）code、Return to Zero（RZ）code and Carrier-Suppressed Return-to-Zero（CSRZ）code . With in the 16×10 Gbps long-distance transmission of DWDM transmission system structure, and take 60 km as transmits per sector (Span) on system, then transmission result is over 26 spans (1560 km), and the error rate (BER) is lower than 10-9. The Q value is bigger than “6” and met ITU-T specification in the DWDM system.
Beside, we using the hybrid Raman/ EDFA amplifier with SMF and DCF to design a long-distance DWDM transmission system , and using new CSRZ-DPSK code, take 32 channels, by the 10Gbit/s speed in C-band, then take 120 km as transmits per sector (Span) on the system is success achieves the transmission 26 sectors (3120 km), and the error rate (BER) is lower than 10-9.The Q value is bigger than “6” and met ITU-T specification in the DWDM system.
