Abstract
A fiber optic fan-out cable having optical sub-units. The optical sub-units are disposed about a central member, at least some of the optical sub-units each respectively comprising a sub-unit jacket, strength fibers, and at least one respective optical fiber ribbon therein. The optical fiber ribbon including a plurality of optical fibers, the strength fibers generally surrounding and contacting the optical fiber ribbon within the sub-unit jacket. A cable jacket surrounds the central member and defines an annular space wherein the optical fiber sub-units are disposed about the central member. The annular space including essentially no strength fibers therein outside of the sub-unit jackets, the strength fibers being essentially located within the optical sub-unit jacket with the respective optical fiber ribbons.
Claims17
A fiber optic cable, comprising:
- optical sub-units disposed about a central member, at least some of said optical sub-units each respectively comprising a sub-unit jacket, strength fibers, and at least one respective optical fiber ribbon therein, the optical fiber ribbon including a plurality of optical fibers surrounded by an extruded matrix material, at least some said strength fibers generally surrounding and contacting said optical fiber ribbon in said sub-unit jacket;
- and
- a cable jacket surrounding said central member and defining an annular space wherein said optical fiber sub-units are disposed about said central member, said annular space including essentially no strength fibers therein outside of said sub-unit jackets, said strength fibers being essentially located within said optical sub-unit jacket with respective said optical fiber ribbons.
A fiber optic cable suitable for indoor use and excluding flooding, filling, and/or thixotropic compounds, said cable comprising:
- at least two layers of optical sub-units disposed about a central member, at least some of said optical sub-units each respectively comprising a sub-unit jacket, strength fibers, and at least one respective optical fiber ribbon therein, the optical fiber ribbon including a plurality of optical fibers, at least some of said strength fibers being stranded about and generally surrounding and contacting each respective said optical fiber ribbon in said sub-unit jacket;
- and
- a cable jacket surrounding said central member and defining a annular space wherein said optical fiber sub-units are disposed about said central member, said annular space including essentially no strength fibers therein outside of said sub-unit jackets, said strength fibers being essentially located within said optical sub-unit jacket with respective said optical fiber ribbons.
