Abstract
A fiber optic cable includes a jacket, strength members, armor, and a tear feature. The jacket is formed from a first polymeric material and defines an exterior of the cable. The jacket further forms an interior cavity configured to support an optical fiber. The strength members are each surrounded by the jacket, with the cavity separating the strength members from one another. The armor extends above the cavity and at least partially above the strength members, and has greater tensile strength than the first polymeric material. The tear feature is located beneath the armor and is formed from a second polymeric material co-extrudable with the first polymeric material. The tear feature forms a discontinuity of material within the jacket. At least one of the second polymeric material and the interface between the first and second polymeric materials yields at a lesser tearing force than the first polymeric material.
