    Wavelength division multiplexing transmission of chaotic optical communication and current optical communication is numerically confirmed and analysed. For a 100 GHz channel span,a 1-Gbit/s digital message extraction is achieved in chaotic optical communication system and a 2.5-Gbit/s digital signal is received in current optical communication system. The results show that when the peak power of digital signal in current optical communication is less than 17 dBm,chaotic optical communication can realise parallel transmission of 80 km. In addition,when the peak power of digital signal in current optical communication is 7 dBm,the quality of the received signal in current optical communication is hardly interfered by signals of chaotic optical communication. As the transmission distance increases from 80 km to 160 km,the opening of the corresponding eye diagram decreases from 82% to 70%.

摘要: 数值证实并分析了混沌激光通信与现行光通信的波分复用传输,对于100 GHz的信道间隔,混沌激光通信系统实现了传输速率为1 Gbit/s数字信号的保密传输,现行光通信系统实现了传输速率为2.5 Gbit/s数字信号的传输.研究表明,当现行光通信中脉冲光信号的峰值功率不超过17 dBm时,混沌激光通信可在传输距离80 km内实现并行传输.此外,当现行光通信中脉冲光信号的峰值功率为7 dBm时,系统接收到的信号质量受混沌激光通信的干扰很小,当光纤传输距离从80 km增加到160 km时,对应的眼图开启度从82%
