Patent ID: 7680365

Claim:
An optical fiber sheet, comprising: optical fibers sandwiched between sheet members and fixed thereto, each of the optical fibers having a glass portion comprising a core portion and a cladding portion, an outer circumferential surface of the glass portion being coated with a resin coating, distal ends of the optical fibers extending from outer peripheral edges of the sheet members with the resin coating applied to the distal ends of the optical fibers to produce extensions; and connectors having fiber holes for insertion of distal ends of the extensions, wherein: the distal ends of the extensions inserted into the connectors have the same resin coating applied to the distal ends of the optical fibers that produce the extensions, and the distal ends of the extensions are inserted into the fiber holes of the connectors, respectively, without the resin coating applied to the distal end of the extensions being removed; wherein the optical fibers are multimode optical fibers, the minimum coating thickness of the multimode optical fibers is 22.5 μm, and the allowable bend radius of the optical fibers wired between the sheet members is 5 mm.
