Low magnetic field effect of circular conductors on a fiberoptic transmission system

Abstract

Abstract In a communication system that uses fiber optics, light wave transmissions respond to the influence of surrounding magnetic fields, thereby causing undesirable changes in the output signal. Thus, an important task in electrical engineering is analyzing polarization and intensity changes to protect sensitive data transmission systems from unintended sources of magnetic disturbance. In this study, we propose a signal processing method to evaluate fiber-optic transmission systems under the influence of a weak magnetic field. This method is conducted by performing experimental and theoretical measurements on the axis of light propagation using a laboratory setup and simulation software OptiSystem (version 7.0). Results show that the shape, size, and axial positions of the conductor plays a key role in strengthening the magnetic field influence on increasing the bit error rate and decreasing the Q factor of the communication system.
