Abstract
Embodiments of a method and apparatus for controlling the mechanical stabilization of an optical fiber are disclosed. The method may consist of placing an inflatable bladder between an optical fiber and a protective jacket. The bladder may be inflated with air, inert gas, or liquid to a desired pressure. The bladder may be sectioned to extend along part of or the entire length of the fiber. The bladder may isolate the optical fiber in a periodic fashion. The temperature of the material inside the bladder may vary axially along the optical fiber. Embodiments of the invention can stabilize the optical fiber by providing mechanical isolation from vibration and other perturbations. Embodiments of the invention can also alter Stimulated Brillouin Scattering (“SBS”) and Stimulated Raman Scattering (“SRS”) thresholds using either thermal or vibrational perturbations.
