摘要

在本文中，我们展示了一个具有不同调制技术的光正交频分复用(OFDM)强度调制和直接检测(IM/DD)系统，如正交调幅(QAM)和相移键控(PSK)。为了获得最佳的误码率(BER)性能，在IM/DD系统中采用了16个QAM和16个PSK调制方式。根据最佳误码率选择下行数据速率为10 Gbps，传输距离为100 km。与其他调制技术相比，具有16个QAM和128个子载波的IM/DD系统具有最佳的误码率性能。

Comparison of different modulation techniques for optical OFDM Intensity Modulation and Direct Detection IM/DD system

In this article, we have demonstrated an Optical Orthogonal Frequency Division Multiplexing (OFDM) Intensity Modulation and Direct Detection (IM/DD) system with different modulation techniques such as Quadrature Amplitude Modulation (QAM) and Phase Shift Keying (PSK). 16 QAM and 16 PSK modulation with different number of subcarriers are applied to IM/DD system to achieve the best Bit Error Rate (BER) performance. According to best BER, the downstream data rate and transmission distance were choosing to be 10 Gbps and 100 km, respectively. Compared with other modulation techniques, IM/DD system with 16 QAM and 128 subcarriers achieved the best BER performance.
