中文摘要	the dispersion compensation effect of the chirped fiber grating (cfg) is analyzed theoretically, and analytic expressions are derived for composite second-order (cso) distortion in analog modulated sub-carrier multiplexed (am-scm) cable television (catv) systems with externally and directly modulated transmitters. simulations are given for the two kinds of modulations and for standard single mode fiber and non-zero dispersion shift fiber (nzdsf) systems. the results show that cfg could be used as a dispersion compensator in directly modulated systems, but its dispersion coefficient should be adjusted much more precisely than the externally modulated system. the requirements for the nzdsf system could be loosened much. it is proposed that directly modulated source may be used as a transmitter in catv systems combined with tunable cfg dispersion compensator being adjusted precisely, which may be more cost-effective than externally modulation technology.
