介紹了組建衛(wèi)星光通信網(wǎng)絡的必要性，分析比較了衛(wèi)星光通信網(wǎng)絡中可采用多址技術及其特點。結合波分復用技術和光碼分多址技術的優(yōu)點，提出一種新的光碼分多址+波分復用組網(wǎng)方案，給出了該組網(wǎng)方案的網(wǎng)絡結構及編碼實現(xiàn)方案，并分析了該種組網(wǎng)方案的特點和應用前景。結果表明，該混合組網(wǎng)方案可很好地利用波分復用和光碼分多址技術的優(yōu)點，具有網(wǎng)絡拓撲結構靈活、易于擴展、可承載多種業(yè)務以及易于實現(xiàn)的特點，在衛(wèi)星光通信網(wǎng)絡中具有重要的應用價值。The characteristics of different access techniques used in optical network are analyzed and compared. A new optical network with Wavelength Division Multiplexing and Optical Code Division Multiplexing Access (WDM/OCDMA) is presented. The advantages and applications of this network scheme are discussed. In the end, the network structure of this WDM/OCDMA network and the optical CDMA encoding and decoding schema are introduced. The results show that the WDM/OCDMA network, which can fully use the advantages of WDM and OCDMA technologies, is valuable in practice.
