However, the fiber strains increase as the pitch decreases, and this becomes one of the dominant reasons for attenuation increase. Furthermore high fiber strains reduce the fiber lifetime and the reliability of the system. The strain distributions in optic fibers caused by stranding and twisting are investigated using finite element analysis with the assumption of large deformation to determine the shortest stranding pitch that gives the maximum fiber strains below lifetime limit. Also, it is necessary that the tubes have sufficient size to endure some compressive load and keep the optical performance. The deformation of loose tube cable under compression is calculated using finite element analysis. The sensitivities of tube size on cable deformation are analyzed from this study.
