Abstract
A device for controlling the twist associated with optical fiber being wo on a bobbin is disclosed. Signal transmission analysis in fibers wound on bobbins require techniques not normally encountered when considering long straight fibers. Signal loss on a fiber cable payout assembly is mainly due to small bends in the fiber at crossover positions and in the transmission regions where the winding travel changes directions. The signal attenuation in a length of optical fiber is also known to be a function of the amount of twist in the fiber both in the wound and payed out states. This invention allows the amount of twist of the optical fiber to be precisely controlled from zero to full (360 degrees twist per turn of the bobbin) twist to provide optimum signal transmission for both the wound and payed out states.
