2011）上，中兴通讯宣布首次实现了24Tb/s（24x1.3Tb/s）波分复用信号传输，是业界首次实现Terabit/s的波分复用技术。以前只有单信道1Tb/s的实验报道，单信道1Tb/s很可能成为单信道100Gb/s后的主流解决方案，其速率将达到100G的10倍。中兴通讯创造了一项光网络技术世界纪录，在100G和超100G光网络领域再次取得技术领先。<BR><BR>该突破具有双重价值。一方面，中兴通讯在此系统中首次实现了Terabit/s的波分复用技术；另一方面，此系统实现了24Tb/s大容量的超长距传输，信号采用“掺铒光纤放大器”，在标准单模光纤中长距离传输了2400公里，相当于从北京到深圳的距离。<BR><BR>在解决Terabit/s的波分复用技术难题方面，中兴通讯此次实现的24Tb/s波分复用系统的传输，采用每信道速率为1.3Tb/s、净荷速率为1Tb/s的12个C波段和12个L波段的传输信号传输，每个信号采用极化复用的QPSK光正交频分复用调制码格式和相干光探测方式接收。<BR><BR>在解决超长距离传输技术难题方面，此次传输系统采用外调制技术产生频率锁定的子载波信号实现了很高的信噪比性能，并对不同波长的光信号透明，从而能够实现波分复用系统实现多波长、超长距离的传输。实验的成功给未来1Tb/s WDM/OTN超长距离传输系统实用化中的子载波产生和波分复用等技术指明了方向。<BR><BR>中兴通讯承载网<a href="http://b.oecr.com/sell" target="_blank" class="relatedlink">产品</a>总经理樊晓兵表示：“感谢OECC对我们在100G技术前沿研究成果的认可，我们一直以来致力于100G及超100G技术的研究，并着力提供IP网络和光传输网络的100G解决方案。未来我们将投入更多精力在100G全球部署上全面应用更多我们的研究成果”。<BR><BR>在Ovum 2010年四季度滚动市场份额分析报告中<a href="http://display.oecr.com" target="_blank" class="relatedlink">显示</a>：中兴通讯年度市场滚动份额全球第三。2010年9月已率先在业内发布全程100G方案，目前中兴已完成单载波400G、1T、10T的系统实验，预计今年三季度，中兴通讯就将发布业内最先进的100G商用设备，以相干探测、软判决FEC等先进技术支持超长距离传输。
