Abstract
A fiber wrap and a method of rotating the fiber wrap without twisting a data cable are disclosed. The fiber wrap includes a sun gear, a sun cylinder coupled to the sun gear, a planetary gear in contact with the sun gear, a planetary cylinder coupled to the planetary gear, an outer housing in contact with the planetary gear, and a data cable coupled to the sun cylinder, the planetary cylinder, and the outer housing. The maximum bend radius of the data cable is determined by the equation: wherein λ is optical wavelength and wherein Cis the stress-optics coefficient, c is the speed of light, Ris the bend radius at the end of the wrap motion, Ris the bend radius at the start of the wrap motion, r is the radii of the sun cylinder and the planetary cylinder, and
