A base plate 9 is bolted to the top of the workbench 10. A vertical plate 5, a take-up / delivery unit 6, and a guide wheel bracket 8 are bolted to the top of the base plate 9. The take-up / delivery unit 6 is located between the vertical plate 5 and the guide wheel bracket 8. A crossbar 4 is bolted to one outer wall of the vertical plate 5. A simulation rod 3 is bolted to the outer wall of the crossbar 4 away from the vertical plate 5. The simulation rod 3 is perpendicular to the crossbar 4 and horizontal to the horizontal plane, ensuring that the optical fiber 2 passing through the simulation rod 3 moves horizontally and avoiding the problem of the optical fiber 2 slipping due to the tilting of the simulation rod 3, resulting in inconsistent wear-resistant positions. The simulation rod 3 can be designed with fixtures of different shapes or sizes according to different work environments. A guide wheel 7 is rotatably connected to one outer wall of the guide wheel bracket 8. The cross-section of the guide wheel 7 is an "I" shape, which can limit the movement of the optical fiber 2. The outer wall of the guide wheel 7 is around which the optical fiber 2 is wound. The optical fiber 2 starts from the left (see attached specification).Figure 1 After passing through the simulation rod 3 in the direction shown, the fiber 2 is vertically downward. The downward end of the fiber 2 on the side of the simulation rod 3 is provided with a tension loading end 1. The test tension range of the tension loading end 1 is 0.5N-5N. The appropriate tension can be selected according to the test requirements. The other end of the fiber 2 is connected to the take-up and take-down unit 6.

[0028] The specific implementation method is as follows: In order to fully control the fiber performance of fiber 2 (after coloring), sampling tests are required for fiber optic trays 68 of various specifications, such as... Figure 1 As shown, the entire optical fiber testing equipment can be placed on the workbench 10 or a mobile platform without the need for a separate bracket design. The specific workflow is as follows: the colored optical fiber 2 is first led out from the optical fiber reel 68 in the take-up and take-down unit 6, then changes direction through the guide wheel 7, passes horizontally to the left through the simulation rod 3 and then vertically downward. The center distance between the guide wheel 7 and the simulation rod 3 is about 1000mm. The tension loading end 1 at the end of the optical fiber 2 is loaded with test tension. The appropriate tension can be selected according to the test requirements. By repeatedly switching the optical fiber reel 68 forward and reverse, the optical fiber 2 and the simulation rod 3 are repeatedly rubbed. After that, the appearance and optical performance of the optical fiber 2 are checked to see if they meet the standards, and whether the inner coating has detached.

The optical fiber tray 68 is provided in various specifications, and the adapter flange 65 matches the optical fiber tray 68, supporting multiple specifications of optical fiber tray 68 to adapt to different test scenarios. The optical fiber tray 68 and the adapter flange 65 are fixedly connected by a quick nut 67. The cross-section of the optical fiber tray 68 and the wire guide wheel 7 are both "I" shaped structures. The other end of the optical fiber 2 is fixedly set to the optical fiber tray 68.
