Description

TECHNICAL FIELD

[0001] The present application relates to a modular automatic counting optical fiber winder. BACKGROUND

[0002] Optical fiber, also known as optical waveguide, is a kind of fiber made of glass or plastic, which uses the principle of total internal reflection to transmit light in the fiber. One of the most important advantages of modern optical fiber is its easy bending. Since optical fiber is to be installed in different situations, optical fiber must be able to bend. When the optical fiber is bent, the light limiting mechanism in the waveguide is disturbed, causing part of the light to escape from the waveguide mode to the leakage mode or even the radiation mode, thereby causing bending loss. Bending loss is a kind of optical fiber loss characteristic. According to the degree of bending of the optical fiber, the bending loss can be divided into macro-bending loss and micro-bending loss.

[0003] When measuring the bending loss of optical fiber in experiments, the transmission loss characteristics of optical fiber are different under different bending radii. Usually in the experimental process, the experimenter cannot well wind the optical fiber according to the same bending radius, and at the same time, the length of the optical fiber cannot be accurately measured, so the experimental results of the bending transmission loss characteristics of the optical fiber have certain errors. When using a common simple optical fiber winder on the market to wind the optical fiber, the winding radius of the winder cannot be adjusted according to the characteristics of different types of optical fiber and the experimental requirements, and at the same time, there are problems such as uneven winding of the optical fiber and difficulty in measuring the length of the optical fiber. Due to the fragile characteristics of the optical fiber, an improper optical fiber winder can easily damage the optical fiber. Therefore, when experiments are performed on different types of optical fiber, an optical fiber winder with different winding radii is required.
