Optical fiber package, package product, stacked body, and method for extracting optical fiber

An optical fiber package comprising:

• a base part;
• a plurality of winding parts protruding from a plane of the base part and configured such that an optical fiber is wound along a portion of each outer circumferential surface thereof;
• and
• a connecting part disposed in a center of the base part and including a lower connecting part protruding from the plane of the base part and an upper connecting part protruding from the lower connecting part,
• wherein the lower connecting part includes a lower hole part, the lower hole part has a lower inner major diameter and a lower inner minor diameter, the lower inner major diameter is a longest inner diameter of the lower hole part, the lower inner major diameter extends in a first direction parallel to the plane, the lower inner minor diameter extends in a second direction parallel to the plane and perpendicular to the first direction,
• wherein the upper connecting part has an upper outer major diameter and an upper outer minor diameter, the upper outer major diameter is a longest outer diameter of the upper connecting part, the upper outer major diameter extends in the second direction, the upper outer minor diameter extends in the first direction,
• wherein the upper outer major diameter is longer than the lower inner minor diameter,
• wherein the lower inner major diameter is longer than the upper outer major diameter, and
• wherein the lower inner minor diameter is longer than the upper outer minor diameter.
