摘要
推进节能减排和促进宽带业务发展一直是宽带领域不断技术创新的重要考量标准,"光进铜退"再次把宽带技术创新带入了一个新的时代和高度。当前,以PON技术为主流的宽带接入思路已经在全球范围内形成共识,数千万线的EPON产品已经成熟应用,10GEPON应用迅速崛起更为EPON的后续发展增添了动力。两种技术的完美兼容性以及在带宽、分光比和接入距离等方面的提升,促进光进铜退网络的持续演进和节能减排的需求。
Promoting energy conservation and development of broadband services is an important standard of considering technological innovation in the fields of broadband.The use of fibre instead of copper leads the broadband technical innovation into a new era and height once more.PON as a mainstream technology for broadband access has reached a consensus on a global scale;the application of tens of millions of lines of EPON products comes to maturity.The rapid rise of application of 10G EPON provides the impetus for the subsequent developments of EPON.the perfect compatibility of both and the enhancement of bandwidth,splitting ratio,access distance,etcetera promote the continuous evolution of the fibre as a substitute for copper network and meet the need for energy conservation and discharge reduction.
