Abstract
An optical fiber cable (10) type comprises at least one tube (12) having optical fibers (14) housed therein. The optical fibers (14) extend helically in a longitudinal direction inside the tube (12). In the method of the invention, the tube (12) is fed to the die for manufacturing the cable (10) by unreeling the tube (12) from the storage reel (24) while the storage reel (24) is held stationary, thereby conferring longitudinal twist on the tube (12) constraining the optical fibers (14) it contains to follow a helical path of pitch substantially equal to the length of one turn of the tube (12) wound on the storage reel (24).
