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100GHz的信道间隔,混沌激光通信系统实现了传输速率为1Gbit/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2.5Gbit/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17dBm时,混沌激光通信可在传输距离80km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7dBm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80km增加到160km时,对应的眼图开启度从82%降到70%.
The chaos laser communication is confirmed by numerical analysis and the wavelength division multiplexing transmission of the current optical communication is realized. For the channel spacing of 100 GHz, the chaotic laser communication system realizes the secure transmission of the digital signal with the transmission rate of 1 Gbit / s, and the existing optical communication system realizes the transmission The rate of 2.5Gbit / s digital signal transmission.Research shows that when the peak power of pulsed optical signal in the current optical communication does not exceed 17dBm, the chaotic laser communication can achieve parallel transmission within the transmission distance of 80km.In addition, when the current optical communication When the peak power of pulsed optical signal is 7dBm, the signal quality received by the system is little disturbed by the chaotic laser communication. When the optical fiber transmission distance is increased from 80km to 160km, the corresponding eye opening degree is reduced from 82% to 70%.
