【摘要】 报道采用光码分多分址(OCDMA)技术实现了3用户通信的实验,传输速率为2.5Gchip/s,传输距离为20km。给出了OCDMA系统基本参数设计方法,搭建并实现了OCDMA实验,通过设计实验系统与得到的实验结果作了详细的分析,结果表明,我们成功实现了3用户传输2.5Gchip/s的OCDMA通信实验,并验证了多用户干扰是OCDMA系统下降的主要噪声源。更多还原

【Abstract】 The experiment of optical code division multiple(OCDMA) technology with active 3 senders and 3 receivers is reported.Design method and some parameters of the OCDMA system are presented,the scheme and experiment results are analyzed in detail,it is shown that OCDMA system with 3 pairs users,2.5 Gchip/s,and 20 km fiber transmission is successfully experimented by optical delay line,the multiple users interference(MUI) effects highly on the bit error rate(BER) performance of OCDMA system is also clarified.更多还原
