PURPOSE:To extend the life of a drill edge, etc. in the stage of working and to improve workability by manufacturing a ferrule body of a resin contg. an inorg. packing material having >=2Mohs hardness and manufacturing an inserting hole part of a soft resin. CONSTITUTION:A hole 16 for introducing an optical fiber core is provided in the central part of a ferrule body 14 and a closing part 17 having a hole 18 for insertion of an optical fiber strand is provided at the center of the top end part thereof. A resin having low shrinkability is preferable as the resin to be used for the body 14. The system which has not only low dimensional change with temp., humidity and chemicals, etc. but also excellent mechanical characteristics such as wear resistance and bending strength, etc. and is added with an inorg. filler having >=2Mohs hardness is used for said resin. An epoxy (phenolic or unsatd. polyester) resin and others such as polycarbonate are used for the resin. Silicon carbide, silica, etc. are preferred for the filler. The resin having good adhesiveness and drill workability is applied for the resin for the part 17. |
