摘要
对于基于10Gb/s以上和DWDM的高速大容量系统来说,限制光通信系统发展的主要矛盾已由衰耗受限转变到以色散受限,非线性受限。将来非线性的矛盾可能会更突出。分析了色散的产生、色散的种类以及克服光通信系统的色散受限的若干因素:光源的预啁啾、波长色散补偿、PMD补偿和色散斜率的补偿。最后指出动态色散补偿是实现全光网的关键技术之一。
The main limitation factors for high speed & large capacity optic telecommunication system have been changed from attenuation to dispersion and non-linear factors The author analyzed that what dispersion is, classes of dispersion and some solution ,Such as Prechirp, dispersion compensation, slope of dispersion, PMD ,auto-dispersion compensation, for dealing with optic telecommunication have been discussed.
