【摘要】：設計了兩種基于光纖布拉格光柵的波分復用(WDM)系統(tǒng),一種為基于光纖光柵的四路波分復用系統(tǒng),另一種為結合光分插復用器(OADM)的四路波分復用系統(tǒng)。給出了基于Opti System的波分復用光傳輸系統(tǒng)仿真模型,對復用及解復用后的光信號進行仿真得出了光譜圖,對傳輸性能及Q因子、誤碼率、眼圖等參數進行分析。在第二種結構中光纖光柵作為色散補償器、光反射器和濾波器使用,可以實現任一波長的上載和下路。兩種波分復用系統(tǒng)眼圖張開良好,誤碼率均低于10e-9。證明了波分復用系統(tǒng)的正確性和設計方案的可行性。

[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，
