摘　　要：提出一种利用逻辑器件搭建的高速双二进制调制(Duo-Binary Modulation,DBM)系统,简述了双二进制调制理论并介绍了新的平台设计方案,实现了在25km标准单模光纤上实时传输速率为10.3125Gb/s的光信号。实验中采用高速误码仪进行检测,实验结果表明,该系统在离线时能实现零误码,在接收光功率为-10d Bm时误码率小于10-7。The paper proposes a way to design high-speed duo-binary modulation（DBM） system based on logic device, it gave out the principle of DBM system and proposes a new method to design the system, then demonstrates a high-speed optic DBM transceiver system transmitting 10.3125Gb/s optical signals over 25km standard signal-mode fiber （SMF）. The high-speed signal quality analyzer is uesd in experiment, the results show that the error bit rate is zero at offline, the bit error rate is less than 10^-7 when the received optical power is -10dBm.

关 键 词：双二进制调制 色散 误码率
