摘要 为了降低直接检测光正交频分复用(DDO-OFDM)系统的成本并提高传输速率,采用载波选择性填充和预加重技术,利用带宽为10GHz的DML激光器实现了信号速率达18.6Gb/s的20km标准单模光纤(SSMF)无色散补偿的传输。实验结果表明利用本方案采用的技术,可以实现结构简单、频谱利用率高、成本低的直接检测OFDM传输系统。 In order to reduce the cost of direct detection optical orthogonal frequency division multiplexing（DDO-OFDM） system and improve the transmission rate,we adopt a 10GHz DML laser as transmitter,using the selective filling scheme and pre-emphasis algorithm.The signal rate is up to 18.6Gb/s and we demonstrate 20km standard single-mode fiber transmission without dispersion compensation.The experimental results show that using this scheme,you can achieve a simple structure,high spectral efficiency,low cost direct-detection OFDM transmission system.
