摘要
实用化的光通信系统在光时分复用 ( OTDM)和 DWDM技术的推动下 ,其容量正有条不紊的向 Tbit/s级发展 .但是限制光通信系统发展的主要矛盾已经发生了根本的变化 :已由衰耗限制转变到色散限制、非线性限制 .将来可能非线性的矛盾会更突出 .文章分析了色散的产生 ,色散的种类 。
With the development of OTDM and DWDM technologies,the optical communication system is evolving towards the Tbit/s class. but the main limitation factors for optic telecommunication system have changed from attenuation to dispersion and non linear factors.The author analyzed the generation of dispersion, the sorts of dispersions and some solutions for overcoming the dispersion limitation.
