摘要： PURPOSE:To realize a method for forming a reinforcing member of a low cost and a reinforcing part of an optical fiber juncture using said member by disposing the optical fiber juncture between a pair of the reinforcing members each of which is constituted by providing an adhesive agent resin layer to the inside surface of a base plate and providing a window part to permit the observation of the inside of the reinforcement to the base plate. CONSTITUTION:The base plate 4 constituting the reinforcing member 6 is made of a metal or heat resistance plastic and is provided with the window 7 to permit the observation of the inside of the reinforcement in the central part. Even if the base plate 4 has the window 7, a plane is formed by fitting a heating part 9 and a projecting part 10 of a plunger die 11 to the window 7, The member 6 is adhered by the adhesive agent resin layer 5 by which the reinforcing part is formed. The reinforcing part is thereafter taken out by removing the heating part 9 and the plunger die 11. A fluororesin is coated 12 on the surface of the projecting part 10 and therefore the reinforcing part can be easily taken out without sticking to the resin layer 5.

摘要： PURPOSE:To unify cutting and welding connection, and to improve the connecting workability by arranging optical fibers of a pair of optical fiber core wires for an axial alignment of a V-groove, etc. so as to have an overlap part in the axial direction, and thereafter, cutting them simultaneously. CONSTITUTION:Two optical fibers 3 which have removed a cover 2 of the tip part of an optical fiber core 1 are brought to an axial alignment by a V-groove 4, when removing the cover, and the covering part is fixed. In this case, the tip parts of the two optical fibers are overlapped on each other, therefore, a bend is generated a little, but it is nearly a neglible extent, since the diameter of the optical fiber is thin in comparison with its length. In this state, the two fibers are cut in a lump by flawing the center 6 of the overlap part of the optical fibers, as shown in (b). Thereafter, in the same way as usual, discharge heating is executed by an electrode 5, as shown in (c), welding is executed, and the connection is completed.
摘要翻译：目的：为了统一切割和焊接连接，并且通过布置用于V形槽等的轴向对准的一对光纤芯线的光纤来提高连接可加工性，使得在轴向上具有重叠部分，然后同时切割。构成：在去除盖子时，已经移除光纤芯1的顶端部分的盖2的两根光纤3通过V形槽4进行轴向对准，并且覆盖部分被固定。在这种情况下，两个光纤的尖端部分彼此重叠，因此，与其长度相比，光纤的直径较薄，所以弯曲产生了一点，但是几乎是可以忽略的程度。在这种状态下，如（b）所示，通过使光纤的重叠部分的中心6发生缺陷，两个光纤被切断。此后，以与通常相同的方式，通过电极5执行放电加热，如（c）所示，执行焊接，并且连接完成。

摘要： PURPOSE:To connect an optical fiber very quickly and easily, and also to execute centering of an optical fiber having an outside diameter difference, by inserting the optical fiber into a hole made in the center of an elastic body, and pushing it into a tapered pipe. CONSTITUTION:In case when an outside diameter difference of an optical fiber is about 10mum, tapered elastic bodies 2, 2' are not required, and a regular pipe is enough. Both ends of its pipe are made round 6, 6' so that the optical fiber can be inserted easily. When raising the axial aligning accuracy of the optical fiber, one elastic body pipe is cut so that the optical fiber is butted at its cut face side. In this regard, in case when eccentricity of the pipe is large, it is necessary to make marks put on in advance on the circumference of the elastic body pipe 4 and 4' coincide with each other. As for the elastic body material, plastic materials such as silicone rubber nylon, polyethylene, polycarbonate, acrylic, resin etc., and a composite material of said materials and a glass fiber, etc. are used.

The outer diameter of the joint can be changed by determining the Young's modulus, thickness and volume of the adhesive 3 and tube 4. The diameter of the joint can be made almost equal to that of the sheath by removing only a part of the sheath radially and fitting the heat shrinkable tube, allowing to increase the strength.

摘要： PURPOSE:To measure the loss of connection while considering directivity by making optical pulses incidence to an optical fiber including connection points and by measuring the power of reflected pulses from the terminal surface of the optical fiber before and after connection. CONSTITUTION:The power P7 of optical pulses from the terminal of an optical fiber 2 is measured by an optical-pulse detection part 10. Then when the transmittivity of an optical powder when an optical beam is emitted from the fiber 2 to the air is gamma and the reflectivity of a half-mirror 8 is beta, P7=P1gamma (1-gamma)beta. An optical fiber 3 is conneced to the optical fiber 2 and a light power P13 of optical pulses from the terminal surface of the optical fiber 2 is measured by an optical-pulse detector 10. Then when the optical transmittivity from the fiber 2 to the fiber 3 and that from the fiber 3 to the fiber 2 are t1 and t2, P13= P1gamma (1-gamma)t1t2beta. Therefore, P13/P7=t1t2, so alpha1=(-10/2)log10P13/P7, where alpha1 is the mean bilateral connection loss of the connection point between the optical fibers 2 and 3. For this purpose, P7 and P13 are measured to obtain the connection loss while considering the directivity.

摘要： PURPOSE:To align the axes of optical fibers having a variation in outside diameter with high accuracy and to connect said fibers by using an elastic material for a cylindrical bar or cylindrical pipe to be used for axial alignment. CONSTITUTION:Elastic material bars 1, 2, 3 are disposed, and optical fibers 4, 5 are inserted into the triangular gaps formed by the circular cylinders thereof and after the fibers are fixed tentatively, a heat shrinkable tube is heated and calked onto the fibers to align the axes of the optical fibers and to fix the fibers, whereby the fibers are connected. If an elastic material having small Young's modulus, such as a nylon rod, is used for the elastic material bar, the diameter of the nylon rod can be changed by calking the same with the heat shrinkable tube or the like; therefore, the outside diameter of the optical fibers to be connected has a degree of freedom, and the connection of the optical fibers having different outside diameters is made possible.
