  • Polarization drift elimination fiber wrap design and method
    Patent number: 7969263
    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 = 0.5 ? C s ? ( r R 2 ) 2 ? ? ? ? L c - 0.5 ? C s ? ( r R 1 ) 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 ? ? ? ? R 2 .
