Problems solved by technology
[0002] In the optical fiber manufacturing industry, the macrobending loss detection of the optical fiber is very important. In the macrobending loss testing process of the existing optical fiber, the optical fiber is usually wound on a common cylindrical test wheel. Because the optical fiber is wound during the winding process, its It is in a state of stress and tension, which leads to inaccurate test results and high human test errors

Embodiment Construction
[0008] Below in conjunction with accompanying drawing, specific embodiment of the present invention is elaborated:
[0009] Such as figure 1 As shown, a macrobending loss test tool for optical fiber includes a rocker 1, a flange 2 and a test axle 3; the test axle 3 is arranged between two flanges 2, and the test axle 3 is provided with a The groove 4 is provided with a rocker 1 for controlling the opening and closing of the groove 4 on the flange 2, and a hinge for controlling the opening and closing of the groove 4 is provided at the bottom of the groove 4.
[0010] Working principle: first wind the optical fiber to be tested on the test wheel shaft, after winding, press the rocker, the concave groove can be changed from a cylindrical state to a partial concave state, and the optical fiber can be adjusted from a stressed state to an unstressed state After starting the test, it can effectively reduce the human test error, and at the same time, the efficiency is improved compa...

The invention discloses a macrobend loss test tool of an optical fiber. The macrobend loss test tool comprises a rocker rod, flanges and a test wheel shaft. The test wheel shaft is arranged between two flanges, a groove capable of being opened and closed is arranged on the test wheel shaft, and each flange is provided with a rocker used for controlling opening and closing of the groove. Compared with the prior art, the test tool of the optical fiber effectively reduces operation effect and improves test efficiency. The optical fiber is first wound around the test wheel shaft, the rocker is pressed after the optical fiber is wound, the recessed groove is changed into the local recessed state from the cylindrical state, and the optical fiber is adjusted to be the non-stress state from the stressed state. The macrobend loss test tool is simple in structure, strong in practicability and suitable for being widely used in industry.
Description
technical field [0001] The invention relates to the optical fiber manufacturing industry, in particular to a macrobend loss testing tool for optical fiber. Background technique [0002] In the optical fiber manufacturing industry, the macrobending loss detection of the optical fiber is very important. In the macrobending loss testing process of the existing optical fiber, the optical fiber is usually wound on a common cylindrical test wheel. It is in a state of stress and tension, which leads to inaccurate test results and high human test errors. Contents of the invention [0003] Purpose of the invention: In order to solve the deficiencies of the prior art, the present invention provides a macrobending loss testing tool for optical fiber with small test result error and high test efficiency. [0004] Technical solution: A macrobending loss test tool for optical fiber, including a rocker, a flange and a test wheel shaft; the test wheel shaft is arranged between two flange...
