The first testing device 2 is used to perform a first test on the optical fiber sensor 100, and the second testing device 3 is used to perform a second test on the optical fiber sensor 100. The first testing device 2 and the second testing device 3 are placed on both sides of the testing device 1 ( Figure 1 left and right sides).

[0025] Figure 2 It is a schematic diagram of a movable rail and a workpiece fixing device provided in an embodiment of the present utility model.

[0026] like Figure 2 As shown, in an embodiment of the present invention, one end of the movable track 4 extends to the area where the first test device 2 is located, and the other end extends to the area where the second test device 3 is located. A workpiece fixture 5 is mounted on the movable track 4, and the optical fiber sensor 100 to be tested is fixed in the workpiece fixture 5. The workpiece fixture 5 can move along the movable track 4, driving the optical fiber sensor 100 to move between the area where the first test device 2 is located and the area where the second test device 3 is located for testing.

[0027] Specifically, in this embodiment, the movable track 4 includes a first guide rail 41 and a second guide rail 42.

The workpiece fixture 5 then approaches the second testing device 3 along the y-direction on the second guide rail 42, so that the main body 31 and the fixing groove 51 are close to or abut against each other. The first reference 53, the optical fiber sensor 100, and the second reference are arranged in parallel, with the input and output ends of the optical fiber sensor 100 aligned with the calibration device 32.
