摘要
随着“宽带中国”战略的深入发展,移动互联网、高清流媒体等新兴业务持续高速增长,各运营商网络的传输带宽需求呈不断上升趋势,推动了400G的发展和建设。因此,介绍了400G OTN的应用场景方案、相关的应用技术及系统建设实践,在400G OTN的建设中扩展了高速传输技术的应用模式,期望在后续实践和发展过程中有其他更优势的技术和方案的推出。
With the in-depth development of the“broadband China”strategy,mobile Internet,high-definition streaming media and other emerging services continue to grow at a high speed,and the transmission bandwidth demand of the operators'networks is on the rise,which promotes the development and construction of 400G OTN.This paper introduces the application scenario scheme,related application technology and system construction practice of 400G OTN,expands the application mode of high-speed transmission technology in the construction of 400G OTN,and expects to introduce other more advantageous technologies and schemes in the follow-up practice and development process.
