摘要： PROBLEM TO BE SOLVED: To provide an optical fiber fixing component which is accurately arranged and fixed optical fibers, and has a strengthened substrate member. SOLUTION: On the beam part 1c of a substrate member 1 where V-shaped grooves 1a for arranging optical fiber elements and casing placing part 1b for mounting a casing of a optical fiber cable, a temporarily positioning member 2 is fixed such that it string over V-shaped grooves 1a. Because the gaps between the temporarily positioning member 2 and V-shaped grooves 1a are smaller than the outer diameter of optical fiber wire, optical fiber wire inserted from back side does not move to its adjacent groove. The substrate member 1 is fixed with a cover member 3 and casing part of the optical fiber cable using adhesive agent such that optical fiber wires which are inserted from back side and arranged on the V-shaped grooves are pushed by the cover member 3.

摘要： PROBLEM TO BE SOLVED: To provide a terminal structure having a sufficient handling resistance strength and by which excellent workability is obtainable without applying the excessive stress by passing plural optical fiber ribbons into a protective tube which is internally formed loose and connecting these ribbons to an optical connector and disposing an optical fibber ribbon length difference absorbing part from a cable end to a connector connecting part. SOLUTION: The ribbon length difference generated by difference in the radius of bending by a ribbon thickness when bending is applied on one piece of the protective tube 4 passing two sheets of the optical fiber ribbons 2 connected to one piece of the optical connector 1 allows the internal optical fiber ribbons 2 to escape to the space 6 on the inner side to the optical fiber ribbon length difference absorbing part 3. The generation of an undue stress is, therefore, obviated and the induction of buckling is averted as well. Further, the protective tube is strong to the external damage by handling. The shape of the protective tube 4 is formed so that a desired number of optical fiber ribbons 2 can be smoothly housed and the respective ribbons are housed loose so as to be able to smoothly move forward and backward.

摘要： PROBLEM TO BE SOLVED: To provide such a multi-fiber optical connector that its connector ferrule is hardly affected by an external force and its connection loss hardly increases. SOLUTION: The optical connector is provided with a projection part 1a on the internal surface of a collector adapter 1, and a connector housing 2 is positioned at right angles to an insertion direction by elastically deforming at least one of the connector adapter 1 and connector housing 2. This connector adapter 1 has projection parts 1a vertically and horizontally symmetrically on the internal surface of a square hole. The projection parts 1a are interference parts as to design size and elastically deform when the connector housing 2 is inserted to press the connector housings 2 from its flanks, thereby positioning the connector housing 2 in the center of the connector adapter 1.

摘要： PURPOSE:To connect optics connectors to each other with one optical connecting member and to make the member smaller in size and higher in function by coupling two ferrules having the same structure or different structure back to back and fixing optical wave members, such as optical fibers, therein, thereby forming the optical connecting member. CONSTITUTION:The ferrules 1, 1' joined back to back by an adhesive, such as epoxy resin, internally include the optical waveguide members, such as optical fibers, for coupling both in the form of holding the members in the optical connectors 8 on both sides. The ferrules 1, 1' may be of the same structure even if the end faces on both sides thereof vary from each other but the different structures are more preferable as easy correspondence is possible in the case of pitch conversion of pitch widths varying from each other or arrangement conversion of arrangements varying from each other. Grooves 2, 2' for positioning are for inserting and fixing the optical waveguide members, such as optical fibers and guide holes 5 are for preventing deviation at the time of fixing the optical waveguide members, such as optical fibers, inserted with guide pins by adhesives injected from window parts 6, and for coupling and positioning of the connectors on both sides.
