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: 2??DGD*(c/?) wherein ? is optical wavelength and ?DGD = [0.5Cs (r/R2)2 ?L]/c - [0.5Cs (r/R1)2 ?L]/c wherein Cs is the stress-optics coefficient, c is the speed of light R1 is the bend radius at the end of the wrap motion, R2 is the bend radius at the start of the wrap motion, r is the radii of the sun cylinder and the planetary cylinder, and ?L = (10/360)2?R2.
