FTTx解決方案 返回


通信網絡正在向全光網絡時代發展,光纖接入網將逐步取代原有的銅線接入網。未來幾年,由于高速數據業務及視頻業務的發展、光纖建設成本的加速降低,加之運營商間競爭加劇、國家政策的扶持等因素,銅線帶寬受到嚴重挑戰,光進銅退不可避免,全球的光纖接入將進入大規模建設時期。

FTTx是指把光纖用于接入層網絡,使光纖靠近用戶甚至直接連接到用戶的接入組網方式。光纖接入網采用光纖作為傳輸媒質,具有傳輸容量大、傳輸質量高、高可靠性、傳輸距離長、抗電磁干擾等優點,是未來固定寬帶接入的發展方向。近年來,人們的需求已經由單純的語音通訊向多媒體通訊邁進,隨著IPTVHDTV,體感游戲,數字家庭等業務的興起,傳統接入方式已經無法滿足日益攀升的帶寬要求。FTTx接入速率可以高達20Mbit/s~100Mbit/s,未來隨著設備技術的進一步提升,還可進一步提高帶寬,憑借其無法比擬的帶寬優勢而成為必然選擇。

在所有已知的FTTx實現技術中,無源光網絡(Passive Optical NetworkPON)技術以光纖為傳輸媒質,具備高接入帶寬、全程無源分光傳輸的特點,在管理運維、帶寬性能、綜合業務提供、帶寬分配策略、組網靈活性、建設成本等方面,相比其他光接入技術具有明顯的優勢。

日海公司憑借多年來在通訊網絡領域的技術積累和工程實踐,以及對未來光通信系統的獨到見解,面向國內國際通信網絡建設用戶,推出了基于通訊網絡物理連接設備及器件的FTTXFTT0FTTHFTTB+LAN、……FTTCab+xDSL)系統解決方案。提供從通訊局端一直到用戶家庭或辦公室的全光或光銅結合的配線管理產品。
