摘要： An optical fiber preform comprises a central core portion having a maximal value Nc of refractive index in the center, and outside the central core portion, comprising at least a depressed portion having a minimal value Nd of refractive index, a ring portion having a maximal value Nr of refractive index and an outside cladding layer having a maximal value No of refractive index. The optical fiber preform satisfies a relation of Nc≧Nr>No>Nd among the values of refractive index. A method of the optical fiber preform comprises fabricating a glass rod by inserting a rod containing at least the central core portion into a pipe containing at least the depressed portion and integrating them, fabricating a glass pipe having the ring portion, and fabricating a vitreous body by integrating the glass rod and the glass pipe by collapsing after inserting the glass rod into the glass pipe.

摘要： 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.
