Abstract
A non-round fiber optic cable that has improved crush performance is disclosed. The fiber optic cable includes at least one optical fiber, at least one strength element, and a cable jacket having a cavity. The at least one optical fiber is disposed within the cavity. The cable jacket further includes a concave upper wall and a concave lower wall disposed on opposite sides of the cavity, thereby improving the crush performance along the major axis of the optical fiber cable. In other embodiments, the fiber optic cable is a portion of a cable assembly.
Claims28
A tubeless fiber optic cable having a cable cross-sectional area that is non-round, the tubeless fiber optic cable comprising:
- at least one optical fiber;
- at least one strength element;
- and
- a cable jacket the at least one optical fiber being disposed within a cavity having a generally rectangular shape where a major dimension of the cavity is generally aligned with a major axis of the tubeless fiber optic cable, and the cable jacket further includes a concave upper wall and a concave lower wall on opposite sides of the cavity, thereby improving the crush performance along the major axis of the tubeless fiber optic cable.
A tubeless fiber optic cable having a cable cross-sectional area that is non-round, the tubeless fiber optic cable comprising:
- at least one optical fiber;
- at least two strength elements;
- and
- a cable jacket, the cable jacket having a cavity disposed between the at least two strength elements and having a cavity cross-sectional area, the at least one optical fiber being disposed within the cavity, wherein the cavity cross-sectional area is greater than about 25% of the cable cross-sectional area, the cable jacket further including a concave upper wall and a concave lower wall, thereby improving the crush performance along the major axis of the tubeless fiber optic cable.
A tubeless fiber optic cable having a cable cross-sectional area that is non-round, the tubeless fiber optic cable comprising:
- at least one optical fiber;
- at least one strength element;
- and
- a cable jacket, the cable jacket having a cavity with a cavity cross-sectional area, the at least one optical fiber being disposed within the cavity, wherein the cavity cross-sectional area is greater than about 25% of the cable cross-sectional area, the cable jacket further including a concave upper wall and a concave lower wall, wherein the radius of curvature of both a first major surface and a second major surface of the cable jacket are between about 20 millimeters and about 100 millimeters;
- thereby improving the crush performance along the major axis of the tubeless fiber optic cable.
A fiber optic cable assembly having a tubeless fiber optic cable with a cable cross-sectional area that is non-round, the fiber optic cable assembly comprising:
- at least one optical fiber;
- at least one strength element;
- a cable jacket, the cable jacket having a cavity with a cavity cross-sectional area, the at least one optical fiber being disposed within the cavity, wherein the cavity cross-sectional area is greater than about 25% off the cable cross-sectional area and the cable jacket further includes a concave upper wall and a concave lower wall, thereby improving the crush performance along the major axis of the tubeless fiber optic cable;
- and
- at least one ferrule for providing optical connectivity.
