CATV
Using OptiSystem to analyze CATV systems
The aim of this material is to show the possibilities of using OptiSystem to analyze CATV systems.
In Part I, we demonstrate the basic nonlinear distortions that result from the propagation of the multiple carrier frequencies through a laser diode.
Observation of harmonic and intermodal products is presented. Although the appearance of the nonlinear distortions is a deterministic process, it is considered to contribute to the laser noise.
