PURPOSE:To enable connection with high accuracy by using a plug of a simple construction by joining by melt sticking the ends of both optical fibers to be connected to a standard optical fiber having high dimensional and shape accuracy, and positioning the end face of the standard optical fiber on the end face of the connector plug. CONSTITUTION:The end faces of respective optical fibers 4, 4 are joined by melt sticking to optical fibers 9, 9 of a core 6 by using the length at which the light loss of the core 6 having a standard optical fiber 9 of high dimensional and shape accuracy is negligible in connection of the optical fiber cores 3, 3 of optical cables 8, 8. The core 6 is cut so as to allow the fibers 9, 9 to remain to a prescribed length from the melt stuck juncture 7 as shown by broken lines. The end faces of both fibers 9, 9 are aligned to the end faces of plugs 1, 1, and the plugs 1, 1 are connected in a sleeve 2. Even if the fibers 4 and the hole diameter of the plugs 1 are not finished to high accuracy, the easy connection with high accuracy and low loss is made possible by using the fiber 9, and on- site connection is feasible, thus the method is helpful in reducing the cost. |
