摘要： To provide an optical fiber cable having a protective structure of an optical fiber connecting part that allows easy fabrication of a protective structure part having a decreased diameter without use of a metal rod and a heat-shrinkable tube, and a method for manufacturing the same. The problem is solved by an optical fiber cable (30) comprising a connecting part (3) of two optical fibers (10A, 10B), each configured by an optical fiber core wire (1) and a coating material (2) coating the optical fiber core wire (1), formed by peeling off the coating material (2) at tip end portions thereof, abutting tip ends of the optical fiber core wires (1) thus exposed against each other, and fusing and splicing the tip ends together, a resin cured product (4) provided to an outer periphery of the connecting part (3) to have an outer diameter that is the same or substantially the same as an outer diameter of a portion of the optical fiber provided with the coating material (2), a metal pipe (6) provided to an outer periphery of the resin cured product (4) with an adhesive layer (5) interposed therebetween, and an outer sheath (7) composed of a resin tube or an extruded resin layer and covering an entire length including the metal pipe (6).

摘要： To provide a tapered optical fiber having a good outer diameter accuracy and a high reproducibility, a manufacturing method of the tapered optical fiber, and a manufacturing system of the tapered optical fiber. The above-mentioned problem is solved by manufacturing system 1 of a tapered optical fiber comprising: shifter 11, 12 which reciprocates optical fiber 10 mounted at positions having a prescribed distance therebetween in the longer direction X of optical fiber 10 (the direction of the optical axis); and heating device 13 which heats the reciprocating optical fiber 10 at fixed position O, wherein shifter 13 includes a broadening unit which can increase the mounting distance (L1+L2) of the optical fiber while reciprocating the optical fiber. Shifter 11, 12 has at least two mounting unit which fix the optical fiber 10, and serves as a broadening unit controlling the two mounting unit independently or interlockingly. The control is performed to in order to change at least one of the ranges of reciprocal movement, the reciprocal movement speed, and the broadening width of the optical fiber fixed on the mounting unit.
