对混沌光通信（COC）和传统光纤通信（CFOC）的波分复用（WDM）传输进行了数值验证和分析。对于80公里长的双通道通信系统，COC通道中的1 Gb/s安全消息和CFOC通道中的10 Gb/s数字信号以100 GHz通道间隔同时实现。我们的数值模拟表明，当CFOC信道峰值功率小于8dBm时，COC和CFOC可以实现80公里的无串扰传输。我们还发现，当信道间隔超过100GHz时，COC和CFOC之间的串扰不依赖于信道间隔。此外，通过比较COC在四通道和六通道WDM系统中的同步性能，串扰并不限制通道数量。
Wavelength division multiplexing (WDM) transmission of chaotic optical communication (COC) and conventional fiber-optic communication (CFOC) is numerically confirmed and analyzed. For an 80-km-long two-channel communication system, a 1-Gb/s secure message in COC channel and 10-Gb/s digital signal in CFOC channel are simultaneously achieved with 100 GHz channel spacing. Our numerical simulations demonstrate that the COC and CFOC can realize no-crosstalk transmission of 80 km when the peak power of CFOC channel is less than 8dBm. We also find that the crosstalk between COC and CFOC does not depend on channel spacing when the channel spacing exceeds 100GHz. Moreover, the crosstalk does not limit channel number by comparing the synchronization performance of COC in four- and six-channel WDM systems.
