The effect of four‐wave mixing on the performance of CATV‐SCM systems, in which the optical carrier is either amplitude or phase modulated, has been evaluated, considering both direct and coherent detection. Four‐Wave‐Mixing is a nonlinear phenomenon arising in single‐mode fibers when input optical power is too high and / or channel spacing is excessively narrow. The penalty induced by this phenomenon on the carrier‐to‐noise ratio has been evaluated assuming the FWM as a noise process that affects the amplitude and phase of the useful signal. © 1994 John Wiley & Sons, Inc.
