通过实验，在使用未冷却直调3.63 GHz垂直腔面发射激光器的简单强度调制和直接检测系统中，首次证明在800 m OM2多模光纤上采用正交频分复用技术进行64 QAM（正交幅度调制）编码实现实时点到点通信，传输速度为11.25 Gb/s，功率损失＜1 dB。%11.25 Gb/s 64-QAM-encoded real-time end-to-end optical OFDM transmission over 800 m OM2 MMFs with a power penalty of <1dB is experimentally demonstrated,for the first time,in simple IMDD systems employing un-cooled directly modulated 3.63 GHz VCSELs.
