Optical fiber measuring device

The invention discloses an optical fiber measuring device which comprises a data display device, wherein the data display device is connected with a detection platform; a groove is formed in the vertical direction of the detection platform; a clamping device is arranged at the upper end of the groove; a sliding groove is formed inside the groove; a sliding block is enabled to slide upwards and downwards freely inside the groove along the sliding groove; the sliding block is connected with the data display device through a sensor. Due to arrangement of the clamping device, one end of an optical fiber can be stabilized inside the groove of the detection platform, and the groove is formed in the vertical direction of the detection platform, so that due to the structural arrangement, the optical fiber can be tensioned by virtue of the gravity of the sliding block self, the rigid tension strength of the optical fiber can be obtained, and thus the data can be fed back to the data display device. Furthermore, the da
