给出采用啁啾光纤光栅进行色散补偿的1 550 nm副载波复用（subcarrier multiplexing, SCM）长距离光纤有线电视(cable TV, CATV)系统的实验结果.对系统中啁啾光纤光栅色散补偿器的最佳位置进行实验，实验结果与理论计算的最佳位置相符，并得到较好的组合二阶互调（composite second order distortion, CSO）输出指标.通过建立200 km传输实验系统，对比有无色散补偿模块（dispersion compensation module, DCM）时的指标测试结果，证明采用啁啾光纤光栅作色散补偿能够改善由自相位调制（self-phase modulation, SPM）效应引起的CSO指标劣化.

We present experiment results of dispersion compensation using chirped fiber grating in 1 550 nm subcarrier multiplexing (SCM) long-haul cable TV (CATV) system. By placing the dispersion compensation module (DCM) at the theoretically optimal position, better composite second order distortion (CSO) is obtained. The test results of 200 km long-haul system with and without DCM show that chirped fiber grating DCM can improve the CSO performance.
