First, the hardening of the adhesive and the end surface being removed by the polishing plate 6 are difficult. Polishing takes a long time.Secondly, since the adhesive 5 is used to fix the optical fiber 2 to the ferrule 4, the adhesive 5 shrinks due to temperature changes, leading to deterioration of the temperature characteristics of the connector. Third, especially when the optical fiber 2 is a stress-applied polarization-maintaining optical fiber, anisotropic stress and slight bending are applied to the optical fiber 2 when the bone cement 5 is cured, which may cause crosstalk. (Leakage) Not only is this a factor that deteriorates the characteristics, but also cracks are likely to occur in the stress-applying portions due to the external force during end face polishing.

After inserting the optical fiber 2 into the insertion hole 4 of the ferrule 3,
The distal end surface 2a of is placed between the electrodes 15 of a discharge device (U and Z shown in the figure), and the distal end surface 2a is polished by discharge sparks. In addition, instead of electric discharge, laser light from a solid laser such as a YAG (yttrium aluminum garnet) laser or a gas laser such as a carbon dioxide laser is applied to the end face 2a.
This may be polished by irradiating it. However, in the case of discharge, the discharge is made in a direction parallel to the tip surface 2a as shown in the illustrated example, but in the case of laser light,
The laser beam is applied perpendicularly to the end surface 2a. Polishing of the tip surface 2a is completed in 2 to 3 seconds for the discharge time or irradiation time for either discharge or laser light.

ル３の融解が起こるようにすることもできる。When the polishing of the tip portion 2a is completed, discharge sparks or laser light similar to those described above are applied from the side of the ferrule 3. This heats the ferrule 3 and the optical fiber 2, and they are fused and fixed as shown in FIG. However, the thermal energy of the discharge or laser beam during this fusion fixing is larger than that during the end face polishing described above. In addition, when the optical fiber 2 and the ferrule 3 are fused and fixed, if there is a risk that the distal end surface 2a of the optical fiber 2 may be distorted due to the heat, the ferrule 3 is fixed at the intermediate portion in the longitudinal direction. It is also possible to melt the ferrule 3 in a short time by forming a narrow diameter portion (necked portion) and applying the discharge or laser light to the narrow diameter portion.

In particular, when the optical fiber 2 is of a polarization maintaining type, this is extremely effective since no anisotropic stress or slight bending is applied due to curing of the adhesive.

In particular, when the bonding method according to the present invention is applied to stress-applied polarization-maintaining optical fibers, excessive bending and slight bending may occur in the optical fibers, which may occur when the bone cement hardens. This method has an extremely large effect in that deterioration of crosstalk characteristics can be prevented because it does not cause cracks in stress-applying parts that might occur during mechanical polishing.
