摘要
介绍了运用增强前向纠错(EFEC)技术实现超长距离传输的10G SDH系统的技术现状,以及10G光-电-光(OEO)和10G EFEC的技术特点,指出了10G OEO+10G EFEC技术是超长距离传输技术发展的方向。通过对比运用喇曼光放技术实现超长距离传输的10G SDH系统,概述了运用EFEC技术实现超长距离传输的10G SDH系统的优势。
The paper introduced the technology status of 10G SDH system to achieve ultra-long-distance transmission by using the enhanced forward error correction(EFEC) technology,it is also presented that the technical characteristics of 10G optical-electricity-optical(OEO)and 10G EFEC,point out 10G OEO+10G EFEC technology is the future development direction of ultra-long-distance transmission technology.Through the contrast with 10G SDH systems to achieve ultra-long-distance transmission by using the Raman optical amplifier technology,it is summarized that the advantage of 10G SDH system to achieve ultra-long-distance transmission by using the EFEC technology.
