Comar electrical components are sensors that convert the state of a measured object into measurable optical signals. The working principle of a fiber optic sensor is to guide the light beam from a light source via an optical fiber into a modulator, where it interacts with external measured parameters, causing changes in the optical properties of the light such as intensity, wavelength, frequency, phase, and polarization state, thereby becoming a modulated optical signal. This signal is then transmitted via the optical fiber to a photodetector and demodulator to obtain the measured parameters. Throughout this process, the light beam is guided through the optical fiber, passes through the modulator, and is then emitted; the primary role of the optical fiber is first
