Abstract :
To improve system composite-second-order (CSO) of an optically amplified AM-VSB CATV transport system, we investigate the system using chirped fiber grating (CFG) and dispersion-compensating fiber (DCF) separately. We find that the CFG technique is superior to the DCF one in both CSO and carrier-to-noise ratio with satisfied composite-triple-beat performance.
