Optical sensor Processing Unit is a highly integrated optical fiber sensing module. Based on the principle of coherent Rayleigh scattering and Brillouin scatterinnulle common single-mode optical fiber is used as the sensing medium, which integrates acoustic wave, strain, temperature and attenuation monitoring. Only one optical fiber is needed to simultaneously measure the changes of various physical parameters alon**e optical fiber. The module has small size, full functions, strong performance, universal communication and data inte**ce, easy integration, and can realize long-distance real-time monitoring of all-round status. This product solves the problem of cross sensitivity between temperature and strain, and provides users with ** reliable ** results.
