The performance of distribution networks based on the subcarrier multiplexing technique is affected by different effects, such as nonlinear distortion and noise. The principal causes limiting the performance are clipping and the combined effect of chirping of the laser source and fiber dispersion. This is reflected by a decrease of the carrier‐to‐noise ratio for CATV analog channels (AM–VSB), and by a detriment of the bit‐error rate for the numerical channels. This paper reports a performance evaluation model that allows all of the effects to be taken into account. An analysis of some relevant cases is reported, showing the impact of both of the main effects. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 20: 200–207, 1999.
