    Abstract: An optical fiber rack includes a rack part on which a plurality of termination units are located, a first optical fiber housing part in which extra length wiring parts of a plurality of first optical fibers are housed, a second optical fiber housing part in which an extra length wiring part of a second optical fiber connected with any of the plurality of termination units is housed, a partition plate partitioning the first optical fiber housing part from the second optical fiber housing part, and, a plurality of optical fiber guides attached to the partition plate and arranged in the vertical direction. The optical fiber guide comprises a first guide part housing the first optical fibers toward to the first optical fiber housing part, and a second guide part housing the second optical fiber passing through an opening provided in the partition plate.

    Abstract: An optical connector is disclosed. The optical connector includes a rear housing, an inner housing, an arm and an outer housing. The inner housing includes at least one retaining hole to house a ferrule. The rear housing moves linearly with respect to the inner housing and rotates with respect to the inner housing. The arm moves linearly together with the rear housing with respect to the inner housing. The outer housing is disposed on an outer periphery of the inner housing so as to cover a front portion of the inner housing. The outer housing rotates with respect to the inner housing by a rotation guiding mechanism cooperating with the arm. The outer housing includes a forward wall covering the distal end of the inner housing. An opening area of the forward wall can be aligned with the retaining hole or a fiber exposure face of the ferrule when the outer housing is rotated with respect to the inner housing from an initial position to a connected position.

    Abstract: An optical connector includes: a ferrule; a mechanical splice mechanically connecting an optical fiber to a shorter fiber; an optical fiber holder fixing the optical fiber in position; a joint member connecting the mechanical splice to the optical fiber holder; a housing accommodating the ferrule and the mechanical splice therein; a rear body accommodating at least a part of the optical fiber holder; and a coil spring urging the mechanical splice toward the front. The joint member is arranged in at least one of the housing and the rear body.The rear body has a guide wall to guide the optical fiber into the mechanical splice, and the guide wall is arranged between the mechanical splice and the optical fiber holder and has a tapered inner wall surface expanding from the mechanical splice toward the fiber holder.
