摘要： The present invention relates to an optical fiber product suitable for fabricating an optical cable that requires a complicated length adjustment. The optical fiber product includes an effective use portion used as the optical cable, surplus portions connected to both ends of the effective use portion, and a distinguishing structure clearly indicating boundary portions between the effective use portion and the surplus portions. With the above structure, the surplus portions that become finally unnecessary are surely cut off in a fabrication step of the optical cable, thus enabling collect use of only effective use portion as the optical cable.

摘要： A method of drawing an optical fiber which can improve the efficiency in manufacture without deforming resin coatings is provided. The method of drawing an optical fiber in accordance with the present invention is a method in which an optical fiber yielding an outside diameter of 300 to 600 &mgr;m after a resin coating is formed is drawn at a drawing speed of at least 50 m/min, wherein the optical fiber is drawn in a state where the pass line length zp from the outlet of curing furnace to the entrance part of capstan satisfies the following expression (1): z p ≥ - ρ ⁢ ⁢ C p _ · d 2 4 · d 2 2 - d 1 2 A · V f · ln ⁡ [ ( T g - 10 ) - T o T s - T o ] ( 1 ) where Tg is the glass transition temperature of the coating resin [° C.]; TS is the fiber temperature [=TF(0)] at z=0 [° C.]; TO is the room temperature [° C.]; {overscore (&rgr;Cp)} is the average heat capacity of glass and resin [J/(cm3·° C.)]; d1 is the radius before coating [cm]; d2 is the radius after coating [cm]; A is a given constant within the range of 1.5×10−6 to 4.5×10−6 [J/(sec·° C.)]; and Vf is the drawing speed [cm/sec].
