Based on the chirp fiber Bragg grating(FBG) and edge filter technique,a high-speed sensor multiplexing network system is designed and realized.By using two FBGs as strain differential sensor,the sensor unit of the system compensates the temperature effects and the total variation in wavelength difference within a large range of temperature is nearly 0.The stress sensitivity has been amplified efficiently and the wavelength resource possession does not increase.According to the system with double channel time-division multiplexing,the relationship between the length of delay fiber and the optical pulse and time-division gate array is analyzed,which coincides with the experimental results.
