Abstract: This apparatus comprises: an installation table for arranging the optical fibers thereon in order to splice the optical fibers; a cover member for covering said installation table; and a gripping mechanism, attached to said cover member, for gripping a storing component that stores the optical fibers.

Abstract: A mid-span branching method for an optical path including a multi-fiber optical cable which is constituted by a multi-fiber ribbon with a plurality of optical fibers arranged in a plane and integrated with a common coating, includes the first step of exposing an intermediate portion of the multi-fiber ribbon from the multi-fiber optical cable (step 101), the second step of extracting the exposed multi-fiber ribbon (step 102), the step of separating at least one single-core optical fiber from the extracted multi-fiber ribbon (step 103), and the step of connecting the single-core optical fiber separated from the multi-fiber optical cable to a single-core optical fiber branched from a branch cable (steps 104, 105).

Abstract: The present invention provides a separating tool for separating a multi-core ribbon fiber obtained by arranging a plurality of optical fibers in a plane and integrating the fibers with a common coating into single-core optical fibers, and includes a fiber accommodating means for accommodating the multi-core ribbon fiber in an accommodating area, a fiber holding means for holding the multi-core ribbon fiber in the accommodating area, a scratching means for forming a scratch on a surface of a common coating of the multi-core ribbon fiber held by the fiber holding means, an arrangement defining means for changing an pitch position of the scratching means, and a shearing force applying means for applying a shearing force to the multi-core ribbon fiber along the scratch formed by the scratching means.

Abstract: A strain relief boot for an optical connector plug which can prevent the occurrence of acute bends of the connection between the optical connector plug and an optical fiber cable, whereby the deterioration of the transmission characteristic of the optical fiber cable can be prevented. The strain relief boot has a first tubular member of Nylon 6.6 having a Rockwell hardness of about 85 and a second tubular member of thermoplastic polyurethane having Rockwell hardness of about 45 connected coaxially with the first member. An outer diameter of the second member is gradually reduced away from the first member, and an end portion of the second member opposite to the first member is shaped in a cylindrical portion a thickness of which is substantially constant. Preferably, the cylindrical portion has a length of above 4.0 mm.

Abstract: A tape core type coated optical fiber containing therein a plurality of single optical fibers, which comprises a housing for housing the tape core type coating optical fiber, the tape core type coated optical fiber branches into a plurality of single fibers inside the housing, the housing comprises a plurality of branches through which each of the single fiber passes.
