我们提出并实验演示了在吉比特无源光网络(GPON)上叠加独立的信道。它的应用是携带从用于公共网络上的环境监测的无线传感器网络收集的数据。覆盖的通道利用高度伸展的脉冲来承载低速率传感器数据，在存在普通数据通道时是不可察觉的。这种覆盖的通道可以为传感器数据提供安全性，因为它的信号幅度非常低。我们的实验表明，GPON传输受到覆盖信道的影响最小，表明了该方法的可行性。提出了一种性价比高的系统架构，并从理论上分析了传感器数据信号对GPON数据传输性能的影响。
We propose and experimentally demonstrate overlaying an independent channel on a gigabit passive optical network (GPON). This has application to carry data collected from wireless sensor networks used for environmental monitoring on a public network. The overlaid channel, which utilizes highly stretched pulses to carry the low-rate sensor data, is unnoticeable in the presence of ordinary data channels. This overlaid channel can provide security for the sensor data because of its ultralow signal amplitude. Our experiment demonstrates that the GPON transmission experiences minimal performance degradation from the overlaid channel, indicating the feasibility of our approach. A cost-effective system architecture is proposed, and theoretical analysis shows the effect of the sensor data signal on the GPON data transmission performance.
