摘　　要：利用反射半导体光放大器(RSOA)的增益饱和原理,设计出一种能同时传输有线和无线信号的载波重用WDM-PON系统。采用光子模拟软件验证了该系统的可行性,同时对影响系统的主要参数进行了分析。分析表明,当PON的线路终端(OLT)中光发射机的发射功率为6.2 dBm,调制器的消光比为20dB,且系统传输距离小于32.8km时,系统的性能较好。Using the gain saturation principle of the reflective semiconductor optical amplifier(RSOA), a carrier reuse WDM-PON system that can transmit wired and wireless signals at the same time is designed.The photon simulation software is used to verify the feasibility of the system, and at the same time the main parameters affecting the system are analyzed. The analysis shows that when the transmit power of the optical transmitter in the PON line terminal(OLT) is 6.2 dBm, the extinction ratio of the modulator is 20 dB, and the system transmission distance is less than 32.8 km, the performance of the system is better.
