OTN中FEC技术的应用
摘要
光传送网(OTN)是随着WDM技术的发展而产生的
ITU T在2001年提出了其接口标准—G.709建议。该建议采用数字包封技术
定义了数据的封装格式
将前向纠错(FEC)技术引入光传送网标准接口中。文章分析了OTN的帧格式
着重介绍了其采用的FEC技术。将G.709标准应用到实际光接口盘的设计中
并通过实验验证了FEC技术的良好效果。
Abstract
OTN(Optical Transport Network)is developed with the progress of WDM technology. The standard G.709 (interface for the OTN) was proposed by ITU-T in 2001.Digital wrapper technology was adopted in the recommendation.The frame structure was defined and FEC technology was introduced in the standard too. The frame structure was analysised and the theory of FEC was introduced in this paper.Digital wrapper technology was used in the design of optical transponder unit.The benefits of using FEC technology were verified by experiment.
