Optical fiber structure and method of manufacturing same

A method of manufacturing optical fiber structure comprising:

• dividing a plurality of optical fibers into multiple optical fiber units consisting of two or more optical fibers, each of said multiple optical fiber units comprising multiple optical fiber core wires that are aligned;
• covering only one surface of each of said multiple optical fiber units by a first covering body;
• separating the first covering body of each of said multiple optical fiber units from the first covering body of an adjacent optical fiber unit with a groove;
• aligning said multiple optical fiber units and placing said multiple optical fiber units on a plane so that the covered surfaces face the same direction;
• and
• covering the covered or uncovered surfaces of the plurality of optical fibers integrally by a second covering body, to integrate the multiple optical fiber units.
