Background
The optical fiber ribbon has the advantages of high density, high space utilization rate and the like, so that the network broadband capacity can be greatly improved, and the optical fiber ribbon cable is more and more widely used in modern network construction. The optical fiber ribbon is composed of ultraviolet curing coated optical fibers and ultraviolet curing adhesive materials, the optical fibers are concentrated in a linear array through the adhesive materials, and the adhesive materials are tightly adhered with the primary coating layers of the optical fibers into a whole. Ribbons can be classified as 2, 4, 6, 12, 24 ribbons, etc. depending on the number of cured fibers.
Optical fiber ribbons are inevitably subjected to torsional forces during the cabling process and during the laying, use and maintenance of optical fiber ribbon cables, and if the optical fiber ribbons cannot withstand a certain torsional force, for example, the optical fiber ribbons are scattered to cause integrity failure, which affects the transmission performance and mechanical life of the optical fibers. In order to test the torsion resistance of the optical fiber ribbon, the mechanical integrity and the functional integrity of the optical fiber ribbon need to be verified by using an optical fiber ribbon torsion testing device.
In addition, due to the structure of the optical fiber ribbon, in most cases, the optical fiber ribbon will twist naturally during use, and when subjected to environmental temperature shock or long-term aging, the degree of twisting will also increase. In order to test the residual torsion angle of the optical fiber ribbon after aging, the natural torsion angle of the optical fiber ribbon needs to be tested by using the optical fiber ribbon torsion angle testing device.

The standard gives a schematic of the test set-up and brief test procedures. However, in the prior art, the torsion test device and the torsion angle test device are separate and independent, and two sets of devices are needed to complete the torsion test and the torsion angle test of the optical fiber ribbon.
In addition, the conventional torsion testing device has the following disadvantages: (1) the length of the sample to be tested is inconvenient to adjust and measure; (2) The twisting is manually operated, the speed and the precision are uncontrollable, the test repeatability cannot be ensured, and the accuracy is not high. The existing torsion angle testing device also has the following defects: (1) the length of the sample to be tested is inconvenient to adjust and measure; (2) The light source irradiation method is inconvenient to operate when the torsion angle is measured; the pointer type device is assembled with a sample and a load, so that the balance of the optical fiber ribbon is influenced, and the measurement result is influenced.
