摘要
　　在本論文中，我們提出結合分時多工與分波多工技術應用於下一代存取網路(乙太被動光纖網路)上。我們所提方案克服了TDM-APON、TDM-EPON和WDM-PON本身對用戶和頻寬受限制的缺點。
對於上行傳送來說，單一波長的傳統TDM-EPON藉由TDM-WDM EPON使形成多波長的傳輸模式，並且使在單一光纖內執行傳送。然後，相似的混合技術也被用於下行的傳送。在上行和上行之間的基本的差別是動態頻寬演算法的技術和輪詢法被用在上行傳送、而下行是採用封包廣播技術。
我們研究的主要貢獻如下:
(一)將分時多工和分波多工兩種技術同時運用到乙太被動光纖網路上。
(二)將分時多工技術藉由分波多工的方式擴展到多個不同的波長上。
(三)比傳統的TDM-APON、TDM-EPON和WDM-PON獲得更多的用戶數和更大的頻寬。
從本篇論文，有助於純光纖到府服務的實現、增加用戶數、降低成本和擴大服務範圍。

Abstract

This thesis, proposes a scheme combining Time Division Multiplex (TDM) and Wavelength Division Multiplex (WDM) technologies for application to the Ethernet Passive Optic Network (EPON). The propose scheme improves the disadvantage of limited users in the case of TDM- Asynchronous Transfer Mode Passive Optical Network (TDM-APON), TDM-EPON or WDM-EPON can be remedied.
For upstream transmission, the traditional TDM-EPON scheme with single wavelength is modified by a multi-wavelength scheme to form the TDM-WDM transmission model, that the transmission is executed in a single optical fiber. Then, the similar hybrid technique is applied to the downstream scheme. The basic difference between upstream and downstream schemes is that the technique of dynamic bandwidth assignment and polling algorithm are used in the upstream scheme.
The main objectives of this study are as follows:
(1) To apply TDM and WDM technologies on the Ethernet Passive Optic Network at the same time.
(2) To apply WDM technology on extending TDM to a lot of specifically independent wavelength by WDM technology.
(3) To get a larger amount of users than TDM-APON, TDM-EPON or WDM-EPON.
From this thesis, readers can to realize that the pure optic fiber connects to subscribers with increasing users of access network, reducing the cost, and extending range of deployment.
