PROBLEM TO BE SOLVED: To provide an optical connector that can be assembled with good workability by using a normal optical connector and a ferrule, can block and/or reflect light at a predetermined wavelength by use of a dielectric multilayer film filter, and can facilitate fiber identification or a test of an optical fiber line.SOLUTION: In the optical connector, a front end of a short optical fiber 12 is inserted and fixed to a ferrule 11; and an end face at an end of a connecting optical fiber 13 is abutted and spliced by a mechanical splicer 16 to an end face at a rear end protruding from the rear side of the ferrule. A dielectric multilayer film filter 15 that blocks and/or reflects light at a predetermined wavelength and transmits light at other wavelengths is directly formed by vapor deposition on an end face 12a at a rear end of the short optical fiber 12. The light at a predetermined wavelength is, for example, visible light or a test light at a wavelength of 1650 nm. |
