Abstract

The invention, which belongs to the field of fiber test, discloses a test tool of macrobend losses of a fiber and a test method thereof. The test tool comprises a plurality of test assemblies. Each test assembly includes a transmission mechanism and a fiber winding column; the multiple fire winding columns in the plurality of test assemblies have different diameters. The transmission mechanisms are configured to drive the fiber winding columns to move. Therefore, macrobend loss testing of different bending radiuses can be carried out on the fiber continuously. Moreover, the test tool has advantages of simple structure, great convenience in operation and high efficiency and can be widely applied to the field of optical fiber testing.

Description

technical field [0001] The invention relates to the field of optical fiber testing, in particular to a tool for testing optical fiber macrobending loss and a testing method thereof. Background technique [0002] The bending of the optical fiber will increase the attenuation of the optical fiber and affect the transmission performance of the optical fiber. G.657 optical fiber is a bending loss insensitive optical fiber, which is widely used in FTTH due to its excellent bending resistance. With the accelerated development of FTTH in recent years, the market demand for G.657 optical fiber is also increasing. Therefore, it is particularly important for optical fiber manufacturers to increase the output of G.657 optical fiber and test its macrobend loss quickly and accurately. . [0003] According to the relevant ITU-T standards, G.657 optical fiber needs to ensure the additional attenuation under different bending radii of 15mm, 10mm, 7.5mm, etc. Macrobend loss test. [0004...
