Abstract
PURPOSE:To obtain a plug which is simple in structure, suitable for the mass production and requires no centering, by providing a very small hole which is slightly larger than the diameter of the optical fiber, on the center axis, and concentrically coating the outside circumferential part of the capillary consisting of a fragile mate- rial, with a metal. CONSTITUTION:The capillary 9 is made of a hard fragile material such as a crystal material, a sintering material, etc., and it is incorporated and fixed in the inside of the tip part 7 of the metallic collar 4'. A very small hole 10 which is slightly larger than the optical fiber strand 3 is provided in the center of the capillary 9. Also, the dimension accuracy of the outside circumferential surface from the collar 6 of the metallic collar 4' to the tip is <=1mum, and the shape dimensions such as roundness, cylindrical property, roughness of the surface, etc. are controlled with high accuracy. Also, as for the assembled plug, the eccentricity between the very small hole 10 and the outside circumferential surface of the metallic collar 4' is controlled to <=2mum. When such a plug 4 is inserted from both the sides of the adaptor 18, the optical fibers 3, 3' are connected with high accuracy. In this way, it is possible to obtain a plug which is simple in structure, high in accuracy, and suitable for the mass production.
