FERRULE

摘要

A ferrule 10 includes holding holes 16, a light incidence/emission plane 21 to pass light entering or emitted from optical fibers F2 respectively held at the holding holes 16, lenses 31 disposed on an optical axes between the respective holding holes 16 and the light incidence/emission plane 21, and two or more guide portions. A second optical axis L2 between the light incidence/emission plane 21 and the ferrule 10 on the other side is inclined relative to a Z direction. A positional relation between the guide portions is 180-degree rotationally symmetric around a reference axial line extending in the Z direction. The lenses 31 is disposed disproportionately in a direction opposite to an inclination direction of the second optical axis L2 from a position line-symmetric relative to a straight line crossing with the reference axial line and parallel to an X direction.

1. A ferrule which is a ferrule on one side constituting a pair of ferrules mutually connectable, the ferrule comprising:
a plurality of holding portions aligned in a first direction and further arranged in one or a plurality of stages in a second direction orthogonal to the first direction, and configured to provide a first optical axis by holding optical waveguide members, the first optical axis extending in a third direction orthogonal to the first direction and the second direction; a light incidence/emission plane configured to pass light entering or emitted from the optical waveguide members respectively held at the plurality of holding portions, and further configured to face the ferrule on the other side constituting the pair of ferrules; a plurality of lenses disposed on optical axes between the respective plural holding portions and the light incidence/emission plane; and two or more guide portions configured to determine a relative position with the ferrule on the other side in the first direction and the second direction, wherein a second optical axis between the light incidence/emission plane and the ferrule on the other side is inclined relative to the third direction, a positional relation between the two or more guide portions is 180-degree rotationally symmetric around a reference axial line extending in the third direction, and the plurality of lenses is disposed disproportionately in a direction opposite to an inclination direction of the second optical axis from a position line-symmetric relative to a straight line crossing with the reference axial line and parallel to the first direction or the second direction.
