Description

technical field

[0001] The invention belongs to the technical field of optical fiber performance detection, and in particular relates to an auxiliary fiber winding tool for optical fiber macrobending loss testing and an application method. Background technique

[0002] The macrobending loss of optical fiber is an important test item for optical fiber performance, especially the bending insensitive single-mode fiber (G.657) series has stricter requirements for macrobending performance testing. When measuring the macrobending loss of a single-mode fiber, it is necessary to wind the fiber into a circle with a certain diameter according to the requirements, and measure the macrobending loss of the fiber by measuring the loss change between the bent and unbent state of the fiber. Most of the auxiliary tools currently used are single coiled cylinders or integrated auxiliary tools. A single coiled cylinder needs to be frequently replaced with multiple coiled cylinders with differen...
