Abstract
A loose-tube fiber optic cable includes a cable core and a jacket. The cable core includes a buffer tube and an optical fiber, where the optical fiber is within the buffer tube. The buffer tube may be positioned at an interior region of the loose-tube fiber optic cable and the jacket may be positioned around the cable core. Material forming the buffer tube may have a composition of greater than or equal to about 70% by weight of a polymer that includes propylene monomers. At least a portion of the polymer may have a beta phase crystal structure characterized by a pseudo hexagonal crystal structure.
