Abstract
The present invention provides methods and systems for mitigating polarization changes associated with an optical communication signal caused by mechanical disturbances to an optical fiber dispersion compensation module of an optical communication network. The methods include disposing a first damping material between an optical fiber and a housing associated with the optical fiber dispersion compensation module; wherein the first damping material is selected and positioned such that it mitigates relatively fast polarization changes. Optionally, the methods also include disposing a second damping material between the optical fiber and the housing associated with the optical fiber dispersion compensation module; wherein the second damping material is selected and positioned such that it mitigates relatively slow polarization changes. Thus, frequency range specific optical fiber dispersion compensation module mechanical perturbation isolation methods and systems are provided.
