Abstract

The dispersion compensation theory of the chirped fiber grating (CFG) in externally modulated CATV lightwave system is analyzed by using the time-domain form of the field envelope wave equation, and the analytic expression of the composite second order (CSO) distortion is obtained. The results show that the requirement of dispersion compensation in externally modulated CATV lightwave transmission system is different from that in common digital optical fiber communication system. Moreover, to a certain fiber transmission link, the dispersion compensation effect is not same for different dispersion compensation position of CFG and it exists an optimal position.
