Abstract
This study investigates the possibility of implementation of quadrature amplitude modulation (QAM) format for optical communication system. In this study, we show different ways of QAM analysis through the constellation diagram and the 16-level eye signal using OptSimTM. The implementation of QAM is also verified using OptiSysTM with the 64-level eye signal. The obtained results analysis shows that, both configuration yield the same QAM results and ensure successful implementation of QAM..
