寬帶接入網(Broadband Access Network)是指連接用戶終端(如家庭、企業)與電信運營商核心網絡之間的高速數據傳輸網絡系統。它作為"最後一公裡"的關鍵基礎設施,通過有線或無線技術為用戶提供高帶寬互聯網接入服務,支撐視頻流、雲計算、物聯網等現代數字應用。以下是技術層面的詳細解析:
物理傳輸層
采用光纖(FTTx)、同軸電纜(HFC)、雙絞線(xDSL)或無線(5G固定接入)等介質,實現用戶端至局端設備的數據傳輸。光纖到戶(FTTH)通過無源光網絡(PON)技術,利用分光器實現單根光纖服務多用戶,典型如GPON标準提供下行2.5Gbps/上行1.25Gbps速率。
協議與标準體系
網絡架構特性
采用分層彙聚結構:用戶端設備(CPE)→接入節點(DSLAM/OLT)→彙聚交換機→核心路由器。動态帶寬分配(DBA)算法保障多用戶公平性,如PON系統中的SR-DBA機制。

“Broadband access network”(寬帶接入網)是通信領域的關鍵術語,其含義可拆解為以下部分綜合理解:
Broadband(寬帶)
指能夠同時傳輸多個頻率信號的技術,提供高速、大容量的數據傳輸。例如光纖、電纜等介質均屬于寬帶技術。
Access(接入)
表示用戶連接到網絡的方式,通常指從終端設備(如家庭路由器)到服務提供商網絡的連接過程。
Network(網絡)
指由傳輸設備、線路和協議構成的通信架構,用于實現數據交換。
綜合定義
