面向下一代的超100G长距离传输技术

摘要

简单介绍了超100G长距离传输面临的挑战，在此基础上，阐述了超100G长距离传输采用的技术，包括调制技术、多载波复用技术、信号处理DSP技术、前向纠错（FEC）技术、光放大技术、光纤技术等，最后介绍了超100G长距离传输系统的商用化情况。%It briefly describes the chal enges for beyond 100G long haul transmission technology. Based on this, it expounds the technolo-gies used by beyond 100G long haul transmission, such as modulation, multi-carrier, signal processing DSP, FEC, optical am-plification, optical fiber. Final y it presents the commercial situation of the beyond 100G long haul transmission system.
