Abstract

PURPOSE:To make a connector for an optical fiber small-sized and low in its cost, by supporting the optical fiber by use of ceramic parts having one or plural through-holes of a free shape. CONSTITUTION:When press-molding a ceramic member 7 being a supporting member of an optical fiber, a fiber consisting of SiO2 glass is embedded to the inside of a molding so as to become a prescribed shape, and this molding is burned, by which a through-hole 8 is obtained on the ceramic member 7. To this through-hole 8, an optical fiber 1 whose covering 2 has been removed is fitted, and in this state, the end face of the optical fiber 1 is polished. Other optical fiber 1 having all the same structure as said fiber, and a supporting ceramic member 7 are junctioned, and are fixed by metallic fittings 9, 10 and 12, and a spring 11.

に示されるような６セラミツクパイプを使用している。The end faces are usually joined by a mechanical method 1c. Figure 1 shows a sectional view of the basic structure of a conventional connector. With two fibers removed, the primary fiber is engaged with the shell of a six-ceramic pipe with one YI through hole. In this state, the single fiber phantom can be polished and joined with the base fiber and ceramic pipe having the same structure. 4
The metal fittings A and 5i fittings B fix each of the six sesimink vises and at the same time guarantee their positional accuracy. The spanning metal fitting C can obtain bonding force through its threaded portion. In this connector structure, a 6-ceramic pipe as shown in the perspective view of FIG. 2 is used.

点があり光通信の普及を太きく阻害していた。Conventionally, in a system with a butt structure as shown in Fig. 1, it is difficult to miniaturize the connector, and when connecting multiple source fibers, separate connectors are required for each system. Overall, the drawbacks were that miniaturization was not possible and the cost was high, which seriously hindered the spread of optical communications.

す。FIG. 6 shows a perspective view of a ceramic member for supporting the original fiber 7 used in the present invention. Conventionally, it was made by extrusion molding, and it was impossible to manufacture anything other than ceramic pipes that had straight H-holes, whereas the support ceramic member 7 has two arc-shaped through holes. . A sectional view of the through hole portion of this ceramic member for support 7 is shown in FIG.

温糺条件が必要である。Table 1 (Light lid) The composition shown in the first coating was mixed in a whole mill for 2 U hours according to the usual ceramic process, then 2% by weight of PVA was added as a binder and granulated.9 The resulting granules The powder is compacted under one pressure. During this pressure molding, fibers made of 8102 glass are embedded into the ceramic molded product in a predetermined shape. By firing this molded product, an 8-shell through hole can be obtained. This through hole is formed by the diffusion of EliQ□ glass fiber into the base material, but the following hot-gluing conditions are required depending on the basic composition of the base material.

は１５８０℃において処理した。The temperature conditions are shown in Table 2. Table 2 Table 2 can be determined by the temperature at which the interaction with 5102 glass starts, and the optimum treatment temperature is about 20° C. above the lowest temperature. In the examples shown in Table 1, the treatment was carried out at 1580°C.

ある。That is, it is necessary to bake for as long as possible near the temperature at which the mutual reaction shown in Table 2 starts in order to stabilize the shrinkage rate and obtain products with good dimensional accuracy and good reproducibility.

はできない。The supporting ceramic member 7 obtained in this way has a high concentration IK of s 1.02 on the surface of the through hole 8, so it is extremely compatible with the original fiber. However, a through hole of any shape can be formed inside the old ramic. Further, in the case of this embodiment, there are only two through holes, but there is an extremely large advantage that a plurality of free-form through holes can be formed depending on the ammonium chloride. One way to obtain porous ceramics is to embed fine i made of organic material inside the ceramic and sinter it at 300°C to 400°C for a long time to vaporize and obtain through-holes, but it is difficult to obtain through-holes during high-temperature reactions. It cannot be used in connectors that have good dimensional accuracy due to deformation, etc., and are difficult to obtain with good reproducibility.

The first fiber, with the second fiber removed, is engaged with the through hole of the supporting ceramic S material 7 described in detail above. In this state, the single-fiber guard face is polished and joined to the single-fiber 7 arbor and 7-supporting ceramic having exactly the same structure. 9 metal fittings, 10 metal fittings E, 12 metal fittings FV (while securing the joint, the degree of f14'tlf is guaranteed. Also, the joining force can be obtained by the 11 spring inside the 10 metal fittings E.

れる。In the connector V having the structure described above, performance such as loss of tS is completely equivalent to that of the conventional connector. In this structure 1, the original fibers and the connector are on the same plane, so it is easy to downsize and the space fastening is extremely good.It is also important to note that multiple original fibers can be joined at the same time. 1 (Multi-functionality V) is advantageous in 4th position, and at the same time, the free-form Sadamitsu entry can be set arbitrarily (・(further development is possible).
