The Optical Fiber Sensing(OFS) technology has been rapidly developing with the evolution of the optical communication technologies and has become one of the main research subjects in the sensing area
in which the environmental monitoring technology using the wavelength shift of FBG is being perfected.As an effective technique for wavelength testing and characteristic of compact package and high reliability
Optical Performance Monitoring(OPM) module can be used to perform accurate monitoring of wavelength shift.In this article
the working principle of FBG and the technical features of OPM are systematically stated and a sensor testing platform is set up on the basis of combining them.
