Abstract
A layered fiber optic cable having a compressible layer for protecting the fiber optic core from damaging displacement due to force from the freezing of trapped ambient water. As ambient water within a protective conduit freezes, the water expands, applying a force on the fiber optic cable within the conduit. The compressible layer absorbs the expansion of the freezing water by compressing, therefore minimizing displacement of the fiber optic core and resulting signal degradation.
