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