The chirp and pulse width of Gauss pulses will be changed after transmitting in optical fiber.The characteristic of Gauss pulses with different chirp and pulse width are different after being reflected by chirped optical fiber Bragg grating(FBG).This article describes the transmission characteristic of chirped Gauss pulses transmitting in optical fiber and reflected by FBG.Both the theoretical analysis and experiments show that the optimal dispersion compensation length is related with the FBG's position in the long length dispersion compensation by FBG.
