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.
