Description

technical field [0001] The invention relates to the technical field of optical fiber performance detection, in particular to a multifunctional auxiliary platform for optical fiber testing. Background technique [0002] Optical fiber cut-off wavelength, mode field diameter, macrobending loss and spectral attenuation are all important test items for optical fiber performance. When measuring these test items, it is basically necessary to take different lengths of optical fibers and wind them into circles of different sizes according to the test requirements. Therefore, when testing different items, it is necessary to use the corresponding coiling tools and various auxiliary tools separately. Most of the auxiliary tools currently used have a single function and can only meet the test requirements of one test item or a type of optical fiber, such as To test various items or types of optical fibers, auxiliary tools need to be replaced frequently, and the existing auxiliary tools h...

[0002] Optical fiber cut-off wavelength, mode field diameter, macrobending loss and spectral attenuation are all important test items for optical fiber performance. When measuring these test items, it is basically necessary to take different lengths of optical fibers and wind them into circles of different sizes according to the test requirements. Therefore, when testing different items, it is necessary to use the corresponding coiling tools and various auxiliary tools separately. Most of the auxiliary tools currently used have a single function and can only meet the test requirements of one test item or a type of optical fiber, such as To test various items or types of optical fibers, auxiliary tools need to be replaced frequently, and the existing auxiliary tools have the following disadvantages:

[0003] 1. Although some test platforms integrate several functions, they are still not comprehensive, and most of them have problems of large size and heavy weight;

[0004] 2. Some tools are extremely inconvenient to use, and the optical fiber is easily affected by various external forces during the test process, and most of the winding methods are manual winding. Since the optical fiber will be bounced off due to its own bending stress after winding, it is necessary to manually Or other heavy objects to fix the fiber, causing the instability of the fiber test and affecting the accuracy of the fiber test results
