RIBBON FIBER AND MANUFACTURING METHOD THEREFOR, AND OPTICAL FIBER ARRAY USING THE SAME

摘要

A ribbon fiber is formed of a plurality of aligned specially processed fibers having a bare fiber portion subjected to predetermined fabrication, and a ribbon portion of 2 to 300 mm in length formed on some of the bare portion; the ribbon fiber being manufactured in such a manner that the specially processed fibers are aligned with a precise pitch width while a length is adjusted so that a lengthwise position of the portion processed as predetermined has a predetermined accuracy, and then a part thereof is fixed by and coated with an adhesive to form a ribbon portion, thereby a ribbon fiber with a great easiness and less expensive is manufactured, and thus manufactured optical fiber can be used to form a fiber array or a half-pitch fiber array.
