2009中国光电产业高层论坛光通信专题论坛40-100G分会主席

演讲题目：基于超高精度色散管理的100G DWDM 传输系统

    宽带应用的普及以及FTTH技术大量商用，使得核心传输网路的容量需求激增，近年100G的超高速传输技术受到广泛的关注，出现了众多的研究方向和解决方案，其中以QPSK和OFDM调制技术，结合相干传输系统的方案得到高度重视，也取得了一些令人鼓舞的进展。同时也存在着相当程度的挑战，其中技术的成熟性和商用可行性最受关注。这些不同技术的根本出发点是试图用电子信号处理技术来解决超高速传输的信号失真以及提高频谱效率。然而超高速A/D, DSP等芯片技术面临着高能耗，高成本的挑战。本文围绕着100G 系统的核心要求，充分利用现有成熟的光技术，尤其是以低成本额的超高精度色散管理技术为核心，设计合理的色散管理， 有效的抑制超高速信号的线性和非线性失真，从而实现了以光技术为核心的低成本100G传输系统方案。
