【摘要】：設(shè)計(jì)了兩種基于光纖布拉格光柵的波分復(fù)用(WDM)系統(tǒng),一種為基于光纖光柵的四路波分復(fù)用系統(tǒng),另一種為結(jié)合光分插復(fù)用器(OADM)的四路波分復(fù)用系統(tǒng)。給出了基于Opti System的波分復(fù)用光傳輸系統(tǒng)仿真模型,對(duì)復(fù)用及解復(fù)用后的光信號(hào)進(jìn)行仿真得出了光譜圖,對(duì)傳輸性能及Q因子、誤碼率、眼圖等參數(shù)進(jìn)行分析。在第二種結(jié)構(gòu)中光纖光柵作為色散補(bǔ)償器、光反射器和濾波器使用,可以實(shí)現(xiàn)任一波長(zhǎng)的上載和下路。兩種波分復(fù)用系統(tǒng)眼圖張開(kāi)良好,誤碼率均低于10e-9。證明了波分復(fù)用系統(tǒng)的正確性和設(shè)計(jì)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，
