Abstract

The invention relates to the technical field of optical fiber signal detection, and concretely relates to strong magnetic field transmission performance detection equipment for optical fibers. The equipment comprises: a rack; a stretching driving mechanism horizontally arranged on the rack; two sets of optical fiber clamping mechanisms arranged at the two output ends of the stretching driving mechanism respectively; two sets of end push-out mechanisms respectively arranged on two output ends of the stretching driving mechanism, and located between the output end of the stretching driving mechanism and the optical fiber clamping mechanisms; an electric signal connection mechanism; a magnetic field generating device; and two sets of magnetic field displacement driving mechanisms arranged on the two sides of the stretching driving mechanism correspondingly. The strong magnetic field transmission performance detection equipment for the optical fibers can stretch the installed optical fibers automatically, and the relationship between the magnetic field and the optical fiber signal transmission performance under different conditions can be comprehensively reflected.

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...
