An object of this invention is to manufacture an optical fiber cable having optical fibers with small characteristic differences at a high yield. Optical fibers in a first span are manufactured (S1), and each fiber is coated with a different color(S2). Each optical fiber is numbered in order of its chromatic dispersion value (S3). Optical fibers in a next span are manufactured (S4), and each optical fiber is arranged in order of its chromatic dispersion value (S5). Each optical fiber of the next span is coated with a color in inverse order to that of the antecedently connected optical fibers (S6). The optical fibers in the next span are connected to the antecedently connected optical fibers so that each optical fiber having a same color couples up (S7). Each connected optical fiber is renumbered in order of its chromatic dispersion value (S8). The operations of S4-S8are repeated until reaching to a predetermined span number S9). When the optical fibers are connected as many the predetermined span number (S9), the optical fibers are bound up into one to make a cable (S10).
