Design of multiparameter fiber Bragg grating in optical transmission systems wavelength division multiplexing

The work presents a brief introduction of fiber optical sensors and focuses on multiparameter grating sensor for measurements of strain, temperature, pressure, acceleration, etc. Two-channel and three-channel fiber Bragg grating (FBG) are designed and simulated using MOD-Grating software, and the reflectivity obtained is 64.8% and 90%, respectively, for both the channels. A wavelength division multiplexed (WDM) optical data transmission system based on fiber Bragg gratings can be developed using the simulation model’s precise and accurate results. The total reflectivity of two-channel optical fiber is 64.8%. In the three-channel FBG, reflectivity of fiber increases from 85 to 90%. The grating sensors are passive elements with two main attributes that are electromagnetic interference (EMI) and multiplexing capability. The presented work gives novel applications of FBG in wavelength division multiplexed optical network. Our design parameters will be helpful for manufacturing and setting up communication channel link in industrial applications in more efficient way.
