摘要： 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.

摘要： An optical connector assembling method capable of preventing workability from worsening is provided. First, when assembling the optical connector, an optical cord (2) is passed through a rear housing (8), an outer jacket holding member (9), a securing member (10), and a boot (11), and an outer jacket (4) is removed from a leading end portion of the optical cord (2), so as to expose a coated optical fiber (3) and a tension-resistant fiber (5). A handled dust cap (16A) is mounted to a ferrule member (6) holding a built-in fiber. Then, a fusion splicer fusion-splices the built-in fiber and the coated optical fiber (3) to each other. Thereafter, while the ferrule member (6) keeps the handled dust cap (16A) mounted thereto, a plug housing (7) is assembled to the rear housing (8). Then, the outer jacket holding member (9) and securing member (10) secure the outer jacket (4) and tension-resistant fiber (5) to the rear housing (8), and the boot (11) is mounted to the securing member (10). Finally, a handle (16a) is cut off from the handled dust cap (16A).
