Description

technical field [0001] The invention relates to the technical field of optical fiber signal detection, in particular to a high magnetic field transmission performance detection device for optical fiber. Background technique [0002] Optical fiber, short for optical fiber, is a fiber made of glass or plastic that acts as a means of light transmission. The transmission principle is "total reflection of light". The transmission principle of optical fiber in optical fiber can be analyzed from two different viewpoints or theories, namely: wave theory and geometric optics ray theory. Wave theory is the benchmark theory for analyzing the principle of optical fiber light transmission. It starts from the basic equations that describe the behavior of electromagnetic waves—Maxwell's equations, and solves the wave equation that satisfies the initial conditions. This analysis method is suitable for any situation and can accurately describe the optical fiber transmission characteristics...
