ABSTRACT:
A fiber optic cable suitable for use in plenum applications comprising at least one optical fiber having a buffer layer formed of a flame retarded polyolefin material, a layer of strength members, and a cable jacket surrounding the optical fiber and in contact with at least some of the strength members. The flame retarded polyolefin can be selected from the group consisting of a flame retarded polyethylene, a flame retarded polypropylene, and blends thereof. Cables made according to the present invention are suitable for use in plenums of buildings, and are designed to meet mechanical and environmental requirements.
