Description

technical field [0001] The invention relates to an auxiliary device for optical fiber testing, in particular to a diameter-controllable optical fiber unwinding device. Background technique [0002] With the rapid development of the optical fiber communication market, the quality of optical fiber as a key transmission medium has been paid more and more attention. While increasing the production capacity of optical fiber, optical fiber manufacturers pay more attention to the control of the accuracy of the key parameters of the optical fiber test, especially for special test requirements. For the test items that have strict requirements on the diameter and length of the loosely wound optical fiber, such as the cut-off wavelength of the optical fiber cable, the optical fiber water immersion test, and the high temperature and high humidity aging test, how to quickly, efficiently, accurately and automatically perform the loose winding of the optical fiber is very important for impr...

Problems solved by technology

[0004] At present, there are two ways to take out 22m optical fibers. One is to manually wind an optical fiber with a certain diameter and approximate length. This method cannot guarantee the accuracy of the fiber diameter and length, and has higher requirements for the fiber winding personnel , which is not conducive to fast fiber winding and efficiency improvement

Another method is to use a loose-winding machine with a fixed diameter for fiber winding. Compared with manual fiber winding, this method has the characteristics of accurate diameter, simple and controllable, but the steps are cumbersome, and the optical fiber is easy to be disturbed and bent, so it is difficult for the later stage. testing inconvenience
