沈陽工程學院畢業(yè)設計

1、沈陽工程學院畢業(yè)設計摘要I摘要網(wǎng)絡融合實現(xiàn)全業(yè)務接入已經成為接入網(wǎng)發(fā)展的必然趨勢，EPON技術在接入速率、帶寬效率、分光比和全業(yè)務承載能力以及安全性方面都具有明顯優(yōu)勢從而成為光纖接入時代的優(yōu)選技術。EPON網(wǎng)絡以光纖為傳輸媒質，使用以太網(wǎng)協(xié)議作為網(wǎng)絡傳輸協(xié)議，利用PON的拓撲結構實現(xiàn)數(shù)據(jù)、語音及視頻的綜合業(yè)務接入。EPON系統(tǒng)主要由OLT（光線路終端）、ONU（光網(wǎng)絡單元）和ODN（光分配網(wǎng)）組成，OLT為局端設備提供豐富的PON口用于

2、連接ONU設備，ONU是用戶端設備提供相應的數(shù)據(jù)和語音接口實現(xiàn)用戶業(yè)務的接入實現(xiàn)。EPON網(wǎng)絡是采用FTTB方式組建，從OLT到ONU采用WDM技術實現(xiàn)單纖雙向傳輸，并使用不同的VLAN標簽來標記相應的用戶業(yè)務流量。本文通過一個小區(qū)用戶實際業(yè)務需求為案例，合理規(guī)劃相應用戶業(yè)務數(shù)據(jù)新建EPON接入網(wǎng)絡，通過對OLT和ONU設備進行相應的硬件和數(shù)據(jù)配置為小區(qū)400用戶提供電話和寬帶業(yè)務服務。關鍵詞以太無源光網(wǎng)絡，光線路終端，光網(wǎng)絡單元沈陽工
