Aimed at the strong bending condition of optical fibers near the stripping points probably leads the fibers to break, the distribution of the bending radius and the bending length near the fibers` stripping points are calculated and analyzed on the basis of the mathematics model of the unreeling kinematic attitude of the optical fiber cable during weapon flight movement. The relationship between the above two geometric quantities and the position of the stripping point are researched. And some other optical characteristic parameters such as the radius of the winding player, speed of the payout optical cable, line density of the optical cable are also studied respectively. The result indicates that the radius of curvature at the stripping point exist a minimal value 1.2 mm, and the value of the minimum almost has nothing to do with the above parameters. However, the bending radius and the bending length will be changed with the diversification of the stripping points location, payout layer, speed and fiber cables linear density.
