Ribbon-like optical fiber core assembly, method for producing the same, tape core assembly-containing connector, tape core assembly-containing optical fiber array, and optical wiring system

A method of separating a ribbon-like optical fiber core assembly into single cores, the fiber core assembly comprising:

• a base layer;
• a plurality of optical fiber cores arranged planarly on the base layer;
• a plurality of position limiting portions limiting a plurality of positions of said plurality of optical fibers;
• an adhesive layer provided on said optical fiber cores;
• and
• at least one tape layer for integrating said plurality of optical fiber cores into one body,
• wherein said at least one tape layer has a tensile strength higher than an adhesive force of said at least one tape layer to said plurality of optical fiber cores,
• said optical fiber cores are compression bonded to the at least one tape layer,
• the adhesive layer is interposed between said optical fiber cores and the at least one tape layer, and
• the plurality of position limiting portions are provided on at least one of the adhesive layer and the base layer,
• wherein the method comprises:
• bending said optical fiber core assembly to break said plurality of optical fiber cores at a predetermined breaking position;
• and
• applying a pulling force on said at least one tape layer in a direction of detachment from said plurality of optical fiber cores to thereby peel said at least one tape layer up to a predetermined position.
