ABSTRACT:
An optical connector in which the housing property into a cabinet or the like can be enhanced because of the compactification, and which can solve problems of the increase of the bending loss of an optical fiber, the breakage, and the like is obtained. In an optical connector which houses and holds a fusion spliced portion where a short optical fiber previously fitted to an optical connector ferrule is fusion-spliced with a coated optical fiber, one end of a protection sleeve which armors the fusion spliced portion is coupled to the optical connector ferrule. As a result, the length of the protection sleeve which covers the fusion spliced portion so that the fusion spliced portion is positioned at the middle can be set with reference to an end portion of the optical connector ferrule. Therefore, the protection sleeve can be shortened, and compactification of the optical connector can be realized.
