摘要

為因應被動式光網路中多媒體寬頻暨高速網路的需求，本文首先介紹乙太被動式光接取網路多工技術的發展。接著說明編碼化分波多工乙太被動式光接取網路的架構。其中以布雷格光纖光柵或陣列波導光柵建構出光網路單元與光線路終端之編、解碼器裝置。

In order to realize broadband and high-speed transmission, the Ethernet Passive Optical Network (EPON) schemes are widely viewed as an ideal solution for first (last) mile access networks. In this paper, firstly, the development of EPON technology such as Time-Division-Multiplexing (TDM-EPON) and Wavelength-Division-Multiplexing (WDM-EPON) over Fiber-to-the-home (FTTx) is presented. Next, the Coded Wavelength-Division-Multiplexing (Coded-WDM) EPON technique over FTTx is configured. The coded-WDM coder/decoder (codec) is set up on Optical Network Unit (ONU) and Optical Line Terminal (OLT) in EPON configuration, respectively. Here, network codecs are constructed with Fiber-Bragg Grating (FBG) or Arrayed-Waveguide Grating (AWG) components.
