There are provided an optical receptacle having an optical fiber including a first portion on another end surface side, a third portion on one end surface side, and a second portion between the first portion and the third portion; a core diameter at the first portion is smaller than the core diameter at the third portion; the core diameter at the second portion increases from the first portion side toward the third portion side; a first elastic member is provided between the optical fiber and an inner wall of a through-hole; a holder holds the another end surface side of a fiber stub; and the sleeve holds the one end surface side of the fiber stub.

A fiber optic connector (20) including a ferrule (42) having a front end (48) and a rear end (50). The ferrule (42) defines an axial bore (46) that extends through the ferrule (42) between the front end (48) and the rear end (50). The ferrule (42) includes a ferrule axis (64) that extends along the axial bore (46). The fiber optic connector (20) includes an optical fiber (62) positioned within the axial bore (46) that is movable relative to the ferrule (42) within the axial bore (46) along the ferrule axis (64). The optical fiber (62) has fiber end face (63) that has been energy treated to round the fiber end face (63). A fiber alignment structure (66) can be attached at a front ferrule end face (54) of the ferrule (42). A camera can be used to position a fiber end face (63) of the optical fiber (62) relative to the front ferrule end face (54) of the ferrule (42).

A transition for an optical fibre cable (11) through a partition. The optical fibre cable (11) is received inside a shield pipe (1, 4), which shield pipe (1, 4) is of an electrically conductive material. The shield pipe (1, 4) is received in an axial through opening (6, 21) of the holding means. One end of the shield pipe (1, 4) is received inside a holding means having a sealing function.

There are provided an optical receptacle having an optical fiber including a first portion on another end surface side, a third portion on one end surface side, and a second portion between the first portion and the third portion; a core diameter at the first portion is smaller than the core diameter at the third portion; the core diameter at the second portion increases from the first portion side toward the third portion side; a first elastic member is provided between the optical fiber and an inner wall of a through-hole; a holder holds the another end surface side of a fiber stub; and the sleeve holds the one end surface side of the fiber stub.

The present invention provides a circuit board-mounted optical interconnection system comprising a mounting bracket for holding a board-based first optical connector ferrule; a ferrule alignment housing for mating the first optical connector ferrule with a second optical connecter ferrule to form a mated ferrule sub-assembly; wherein the mounting bracket comprises a pair of curved portions; the mated ferrule sub-assembly comprises one or more pivoting features for engaging with the curved portions such that the mated ferrule sub-assembly is rotatable with respect to the mounting bracket. The present invention makes mating and un-mating of the connector ferrules easier, particularly in confined working spaces as with racks in telecommunication cabinets.
