Description of the Related Art As a means for measuring the transmission loss of an optical fiber, a method is generally used in which a reference light is made incident from one end to be transmitted through the optical fiber and a transmitted light is detected from the other end. As a related prior art document, there is JP-A-5-273079. However, in the method of winding the optical fiber terminal at a high speed, it is impossible to mount the device on the light extraction side, and the transmission loss measuring means during the high speed feeding test of the optical fiber reel on the ground has not been established. The short mechanical pay-out test could be carried out by a high-speed pay-out test device for a flight-guide piano wire that employs a method of winding the wire rod end at high speed. However, the device measures the electrical continuity during the unwinding behavior due to the characteristics of the piano wire, and since the continuity does not depend on the shape after winding, a disordered winding shape is allowed. Therefore, if several tens of turns are randomly wound around the winding drum, an excessive transmission loss occurs due to microbending of the optical fiber wire due to winding and bending, and it is impossible to measure the loss change during feeding. In the case of a piano wire, long winding around the winding drum is performed by guiding it around the center of the drum with the required groove groove width with guide holes, so that the winding is performed evenly and randomly. It can be tested continuously. However, when an optical fiber is applied to this, it appears to be random, but microscopically small collapse of the winding part breaks the glass of the optical fiber, and it is impossible to wind the drum over a long length at high speed. is there. This is due to the large difference in properties between the metallic material and the brittle fracture material of the test body to be tested and evaluated.

The reflecting mirror 8 is prepared by shortly preparing an optical fiber wire 11 shown in FIG. 3 which is the same material as the optical fiber wire W to be tested, cuts the end face at a right angle, and coats the resin 12 near the cut part.
The optical fiber clad 13 and the optical fiber core 1
After polishing the cut surface 15 of No. 4, gold is directly vapor-deposited on the polished surface to form a reflection surface of the gold vapor deposition film 16, and then two protective resins 17 similar to the coating resin 12 are provided on the outer periphery in the vicinity of the cut portion. After coating as shown by the chain line, the front end portion of the optical fiber wire 11 and the coating resin 12 at the rear end portion of the optical fiber wire W are peeled off, and the optical fiber clad 13 and the front end surface and the rear end surface of the optical fiber core 14 of both wire materials are peeled off. Since the mirror is formed by fusion-splicing and connecting the outer periphery of the connection portion with the protective resin 17, the reflecting surface of the gold vapor deposition film 16 efficiently reflects the incident light and reflects the reflected light in the fiber wire W. Since it was able to pass through and reliably return to the incident side, it was possible to secure the dynamic range and linearity of the loss measurement.

The moving position control of the diameter portion of the fiber wire W can be performed by the winding guide traverser 5,
Even in high-speed winding, the optical fiber wires W can be precisely aligned and wound around the winding drum 2 at a close pitch, and when the winding reaches the end of the cylinder, the traverser 5 immediately reverses and winds up. Since the close-alignment winding around 2 can be realized in multiple layers, one end of the optical fiber wire W is fixed and the drum 2 is applied with tension.
It was possible to minimize the occurrence of transmission loss when wound on a wire, and to suppress the occurrence of microbending loss.

きる。As can be seen from the above description, according to the optical fiber high speed feeding test apparatus of the present invention, it is possible to continuously carry out the winding and feeding test of the optical fiber wire having the required length at a high speed and suppress the occurrence of the winding internal loss. It is possible to realize the loss fluctuation measurement of the reflected light detection method (measurement of fluctuation in units of microseconds in units of 0.01 dB). Therefore, continuous measurement is possible in high-speed optical fiber feeding tests equivalent to the flying speed of a flying object. It is possible to realize both evaluation of mechanical behavior and breakage over a long length, and measurement and test evaluation of optical loss fluctuation in feeding behavior.
