Abstract

A simulation model for laser diode modulation by multichannel 64-QAM and 256-QAM TV signals is developed. The signal/noise (S/N) ratio is used as a criterion for evaluating the quality of TV signals. The effect of nonlinearity of the light-current characteristic on the S/N ratio is studied. Simulation results are presented in the form of a dependence of the maximum number of transmitted channels on the optical modulation depth with certain requirements for S/N. The simulation model is implemented in the object-oriented programming language Delphi 7.
