Abstract

PURPOSE:To remove a primary coating more rapidly and precisely and to obtain a connection part with less connection loss by coloring a primary coating after removing a secondary coating and a buffer layer to check the degree of removal of the primary coating with operator's eyes at the twisting joint of optical fiber cores. CONSTITUTION:At the twisting joint of optical fibers 1 composed of a secondary coating 3, a buffer layer 2 and a primary coating 4, the primary coating 3 and the buffer layer 2 at the end of the twisting joint are removed by a subscribed length at first. The remaining primary coating 4 is colored to get a colored part 5. The colored part 5 is continued to be drawn through the operator's hand with the gauze dipped in organic solvent such as alcohol and acetone until the removal of the colored part 5 is confirmed. Thus, the coating can be removed more rapidly and precisely and unrequired overdrawing can be prevented to obtain a connection part with less connection loss.
