Abstract :
The exact carrier-to-nonlinear distortion (C/NLD) ratio, resulting from laser clipping, is computed for the low, center, and high channels of the analog and digital bands of a hybrid fiber/coax system. The computed results indicate that high capacity digital channels can be added to present analog systems without affecting the high performance analog channels
