在本篇論文中,我們提出三種不同的方式來改善雙向混合式DWDM-PON傳輸系統的效能。
首先,我們提出使用外部光源注入至垂直共振腔面射型雷射及分佈回饋式雷射,作為雙向混合式DWDM-PON傳輸系統的發射光源。主要利用掺鉺光纖放大器所產生出的寬頻自發性輻射放大光源,再經由高密度分波多工/解多工器有效分割成四個光源後作為系統的外部注入光源。其中外部光源注入至垂直共振腔面射型雷射,可以有效增加雷射本身的頻率響應並降低驅動電流,而提高傳輸系統性能。
其次,我們於光接收器後使用資料比較器及相位補償器實施雙向混合式DWDM-PON傳輸。藉由資料比較器及振幅相位補償器對系統的失真信號作補償,再經原先所儲存的原始信號不斷的回授修正、比較及補償,而在最短時間內去除因傳輸過程所引起的失真信號,改善傳輸系統的信號品質。
最後,我們同時使用外部光源注入技術、資料比較器及振幅相位補償器建構雙向混合式DWDM-PON 傳輸系統。實驗結果證明,光信號經過 40 公里的標準單模光纖傳輸後,系統的誤碼率、載波雜訊比、載波合成二次拍差比及載波合成三次拍差比均已獲得改善。
In this thesis, we proposed three different methods to improve the performances of bidirectional hybrid dense wavelength-division-multiplexing (DWDM) for passive optical network (PON) transport system.
First, we proposed a bidirectional hybrid DWDM-PON transport system employing external light injection technique on vertical cavity surface emitting lasers (VCSELs) and distributed feedback laser diodes (DFB LDs). The broadband amplified spontaneous emission (ASE) light source is generated from a 3-stage erbium-doped fiber amplifier (EDFA). The broadband ASE is efficiently divided into four optical channels as injection sources by using DWDM DEMUX. Using an external light injection technique can effectively enhance the frequency response and reduce the driving current of VCSEL. The performance can be raised in our transport system.
Second, we completed a bidirectional hybrid DWDM-PON transport system based on data comparator and amplitude/phase compensator behind receiver. The system of distorted signal was compensated by data comparator and amplitude/phase compensator. Furthermore, the original signal can be continuously feedback in comparator and compensator to correct signal distortion. Thus the system distorted signal can be removed within less time. Therefore, the signal quality can be improved in transport system.
Finally, we employed both of external light injection technique, data comparator and amplitude/phase compensator for bidirectional hybrid DWDM-PON transport system. The experimental results showed that the performances of bit error rate (BER), carrier-to-noise ratio (CNR), composite second order (CSO), and composite triple beat (CTB) were improved over a 40-km standard single-mode fiber (SSMF) transport system.
