摘要： A reinforced structure for a multicore optical fiber coupler wherein a longitudinal coating resin of first and second multicore optical fibers, each having a plurality of optical fiber stands positioned in parallel arrangement to each other and each collectively coated with a respective coating resin, is partially removed so as to expose glass portions of the optical fiber strands of each of the optical fibers. The exposed glass portions are then fused and extended. The fused and extended portions are then accommodated in a plurality of grooves formed in a reinforcing casing. The non-extended portions, which are located on opposite ends of the fused and extended portions in the extending direction, are also accommodated on the surface of the reinforcing casing. The optical fibers are secured to the reinforcing casing with adhesive, which is applied to the non-extended portions of the fibers. The reinforcing casing is preferably made of a material having substantially the same coefficient of linear expansion as that of quartz.

摘要： Optical fibers are fixed to elongating tables by optical fiber fixing jigs. Coatings are removed from portions of the fibers and respective fibers of two different groups are placed into tight contact with one another. The fibers are then heated by a gas burner 4A so as to be welded integrally with each other, and are then elongated. In one preferred embodiment, the fibers are arranged such that there are gaps therebetween. These gaps are substantially 250 .mu.m. The gaps are sufficiently wide that heating gas flows in a manner such that all the optical fiber strands are heated uniformly to make it possible uniform welding and elongation.

摘要： Optical fibers are fixed to elongating tables by optical fiber fixing jigs. Coatings are removed from portions of the fibers and respective fibers of two different groups are placed into tight contact with one another. Rectifier rods, supported movably by rectifier rod supporting members, are disposed outside the optical fiber strands. The fibers are then heated by a gas burner 4A so as to be welded integrally with each other, and are then elongated. By using rectifier rods, the outside optical fiber strands of the groups being welded are not so strongly heated that uniform welding and elongation can be realized. In one preferred embodiment, the fibers are arranged such that there are gaps therebetween. These gaps are substantially 250 .mu.m. The gaps are sufficiently wide that heating gas flows in a manner such that all the optical fiber strands are heated uniformly to make it possible uniform welding and elongation.

摘要： In an optical fiber coupler fabricating process where couplers are successively formed by heating, elongating and cutting a plurality of long optical fibers, light is led into the first end of the fiber, reflected at the second end of the coupler, and the reflected light is monitored by photodetectors. In this manner, an exact splitting ratio can be obtained. Techniques for minimizing measuring errors caused by the inter-reflected-light interference, the inter-Rayleigh-scattering-light interference, and the interference between the reflected light and the Rayleigh scattering light, while exploiting the advantageous feature of the reflection monitor method that the fiber connection work for each fiber coupler fabrication is not required are disclosed.

摘要： An optical fiber coupler having a crosstalk characteristic of at least 18 dB. The optical fiber coupler includes a plurality of optical fibers. A length of glass in the optical fibers is exposed by removing the covering. The glass lengths are fused together and extended, during which time the fibers are twisted and subjected to a tension. The twisted fibers are then fixed to a protecting member while the tension is sustained.

摘要： The present invention provides an optical fiber which has a hollow portion extending along the axis and which reduces degradation of the optical characteristics, and a production method thereof. An optical fiber includes a hollow core portion, and a cladding portion which surrounds the hollow core portion. The refractive index of the hollow core portion is lower than that of the cladding portion. The hollow core portion is closed at both ends of the optical fiber so as to form sealed portions. The sealed portions are formed by, for example, heating the optical fiber and softening the cladding portion. This prevents foreign material and the like from entering the hollow core portion. Ferrules of optical connectors are attached to both end faces of the optical fiber.
