Optical connection component and optical connection structure

An optical connection component comprising:

• three or more cores that transmit optical signals along a first direction;
• a first surface extending in a second direction intersecting the first direction and in a third direction intersecting both the first direction and the second direction;
• and
• a second surface extending in the second direction and the third direction and arranged with the first surface along the first direction,
• wherein each of the cores extends from the first surface to the second surface along the first direction,
• the three or more cores are disposed not to be arranged on one straight line on each of the first surface and the second surface,
• a core disposition on the first surface defined by the three or more cores is different from a core disposition on the second surface defined by the three or more cores;
• and
• a single-core fiber holding portion that holds a plurality of single-core fibers optically connected to the respective cores disposed on the first surface,
• wherein the single-core fiber holding portion is open toward the first surface, and has a plurality of holes corresponding to the plurality of single-core fibers.

An optical connection structure connecting a plurality of single-core fibers and one or a plurality of multicore fibers via an optical connection component,

• wherein the optical connection component includes three or more cores that transmit optical signals along a first direction, a first surface extending in a second direction intersecting the first direction and in a third direction intersecting both the first direction and the second direction, and a second surface extending in the second direction and the third direction and arranged with the first surface along the first direction,
• each of the cores extends from the first surface to the second surface along the first direction,
• the three or more cores are disposed not to be arranged on one straight line on each of the first surface and the second surface,
• a core disposition on the first surface defined by the three or more cores is different from a core disposition on the second surface defined by the three or more cores,
• the plurality of single-core fibers are connected to the first surface, and
• the one or plurality of multicore fibers are connected to the second surface.
