LI Lan, ZHANG Zheng-ping. Study on the Suppression of Power Fading for IM-DD CAP-16QAM Transmission System[J]. 2017,(3):9-11. DOI: 10.13756/j.gtxyj.2017.03.003.
In Intensity Modulation Direct Detection(IM/DD)optical transmission system with Carrierless Amplitude and Phase modulation Quadrature Amplitude Modulation(CAP-16QAM)
the system capacity is limited due to the power fading effect caused by the dispersion and chirp of intensity modulator.In this paper
we use optical domain equalization scheme based on optical Fiber Bragg Grating(FBG)to realize the optical Vestigial Sideband(VSB)filtering.The simulation results show that the 40Gbit/s CAP-16 QAM system performance after 60 km transmission have been improved by using the proposed equalization scheme
which mitigate the power fading effect efficiently.
