Hi accordance with the physical principle of dispersion generation , many kinds of technologies of dispersion compensation have been researched and expounded . for instance , dispersion compensation fiber technology , pre - chirpped technology , dispersion supported transmission technology , chirpped fiber grating technology , and so on . but the study of dispersion compensation technology in which the dispersion of the optical signal in every channel in the wdm system is compensated respectively is reported rarely 针对色散的物理机理，人们研究并提出了各种色散补偿技术，如色散补偿光纤法、预啁啾法、色散支持传输法和啁啾光纤光栅法等，而对波分复用系统中各分波光信号分别进行有针对性的色散补偿的研究报导还很少。
