发布时间：2019-07-09 18:06
【摘要】：设计了两种基于光纤布拉格光栅的波分复用(WDM)系统,一种为基于光纤光栅的四路波分复用系统,另一种为结合光分插复用器(OADM)的四路波分复用系统。给出了基于Opti System的波分复用光传输系统仿真模型,对复用及解复用后的光信号进行仿真得出了光谱图,对传输性能及Q因子、误码率、眼图等参数进行分析。在第二种结构中光纤光栅作为色散补偿器、光反射器和滤波器使用,可以实现任一波长的上载和下路。两种波分复用系统眼图张开良好,误码率均低于10e-9。证明了波分复用系统的正确性和设计方案的可行性。

[Abstract]:Two wavelength Division Multiplexing (WDM) (WDM) systems based on fiber Bragg gratings (FBG) are designed, one is a four-channel WDM system based on fiber gratings (FBG), the other is a four-channel WDM system combined with optical add / drop demultiplexer (OADM) (Optical add / drop Multiplexer). The simulation model of wavelength division multiplex optical transmission system based on Opti System is given. The spectrum of the optical signal after reuse and demultiplexing is obtained, and the transmission performance, Q factor, bit error rate, eye diagram and other parameters are analyzed. In the second structure, fiber grating can be used as dispersion compensator, optical reflector and filter to upload and lower any wavelength. The eye diagram of the two WDM systems is well opened, and the bit error rate (BER) is lower than 10 e 鈮，
