Abstract: An optical connector apparatus includes a first connector having a first connecting portion adapted to be connected to and disconnected from a first connecting object in a first direction, a second connector which has a second connecting portion adapted to be connected to a second connection object and which is coupled to the first connector, and an optical fiber connected between the first and the second connectors. The first connector includes a first ferrule having an end portion formed at a position corresponding to the first connecting portion and having a first outer diameter. The second connector includes a second ferrule having an end portion formed at a position corresponding to the second connecting portion and having a second outer diameter greater than the first outer diameter. The optical fiber is coupled to the first and the second ferrules.

Abstract: In a fixing apparatus for fixing an optical connector to an optical cable having an optical fiber and wire members arranged around the optical fiber, the fixing apparatus includes first, second, and third holding members. The first holding member is adapted to be inserted between the wire member and the optical fiber. The second holding member is adapted to be disposed outside the wire members, the second holding member cooperating with the first holding member to tightly hold the wire members therebetween. The third holding member surrounding the second holding member and having an axial end portion adapted to be engaged with the second holding member in a rotation direction with respect to the optical cable. In addition, the third holding member has another axial end portion adapted to be connected to the optical connector.
