Resolusi bit yang diperlukan penukar digital-analog (DAC) untuk OFDM optik telah dinilai melalui simulasi dan eksperimen. Kami mendapati bahawa kemerosotan isyarat yang disebabkan oleh pengkuantitian bergantung pada bilangan subpembawa secara teori, tetapi hingar lain yang dijana dalam eksperimen menindas pergantungan. Selain itu, kemerosotan isyarat yang disebabkan oleh kuantisasi adalah bebas daripada modulasi subcarrier, dan peningkatan prestasi tepu dengan peningkatan resolusi bit. Dengan kriteria untuk BER 1

Abstract: The required bit resolution of digital-analog-converter (DAC) for optical OFDM was evaluated through simulation and experiment. We found that the signal degradation caused by quantization depends on the number of subcarriers theoretically, but the other noise generated in experiment suppresses the dependency. Additionally, signal degradation caused by quantization is independent of subcarrier modulation, and the performance improvement saturates with increasing bit resolution. With the criteria for the BER of 1
