中華電信與NTT合作5G光傳送網路開放介面標準
中華電信與日本NTT合作制定5G光傳送網路開放介面規範,並於2018年第四季於國際寬頻論壇(Broadband Forum, BBF)發佈為TR-402與TR-403標準。將使未來能依用戶需求,動態調度光纖網路資源,滿足5G高頻寬、低時延服務品質要求。
為解決未來5G行動或固定網路用戶即時性應用服務議題,中華電信與NTT於2017年5月簽署合作協議,基於5G應用需求,研訂被動光纖網路(Passive Optical Network, PON)動態頻寬配發(Dynamic Bandwidth Assignment, DBA)及動態波長調訂(Dynamic Wavelength Assignment, DWA)之使用情境及開放介面規範。合作成果於2018 Q4 BBF會議發布為標準文件(註)。依循此標準,未來光纖網路可按需建立服務模組,滿足即時且彈性控制目標。
中華電信為提供客戶高頻寬及高品質的電路服務,持續建設光纖接取網路並採用最新技術。這次與NTT共同完成的標準,為5G 所需的接取傳送網路奠定重要基礎。
中華電信網路亦朝軟體化演進,有助於國內網通業者發展白牌通用型設備(White-Box),拓展國際市場。中華電信將持續攜手國內廠商逐步實現電信網路的雲網融合願景,透過標準化的開放介面,提升應用服務的佈建彈性,加速新服務開發導入,提供客戶更先進與智慧化的資通訊服務。
