METHOD OF REMOVING JACKET OF COATED OPTICAL FIBER

摘要

PURPOSE:To suppress the swelling in parts exclusive of a jacket removing part so as to prevent the deterioration thereof and to improve the reliability of an optical fiber juncture by immersing the part adjacent to the jacket removing part into a non-swelling soln. CONSTITUTION:The length of the part where the jacket is to be removed is first determined and is notched in the position shown by A in the case of connecting coated optical fibers 1. The fiber is immersed into the liquids in a container 2 in such a manner that the notched part A coincides with the boundary of the two liquids in the container. The jackets in jacket removing part swells and is strippable upon lapse of several minutes in this state. Methylene chloride is used for the swelling soln. 3 and water is used for the non- swelling soln. 4 which does not dissolve therein. The swelling of the parts exclusive of the jacket removing part is suppressed in this way, by which the deterioration thereof is prevented and the reliability of the optical fiber juncture is improved.
