Abstract
A fiber optic distribution cable includes a jacket defining an exterior of the fiber optic distribution cable and a plurality of optical fibers extending through a cavity of the jacket. The jacket has an access location with a single opening formed in the jacket that extends to the cavity. A distribution optical fiber of the plurality of optical fibers extends through and protrudes from the single opening in the jacket at the access location. The length of the distribution optical fiber is at least 5/4 times the length of the single opening.
Claims19
A fiber optic distribution cable, comprising:
- a jacket defining an exterior of the fiber optic distribution cable, wherein the jacket defines a cavity therein and has an access location with a single opening formed in the jacket that extends to the cavity;
- and
- a plurality of optical fibers extending through the cavity of the jacket, the plurality of optical fibers comprising a distribution optical fiber that includes a severed optical fiber that extends through and protrudes from the single opening in the jacket at the access location, the distribution optical fiber having an end that would extend to, but not beyond, a cutting location within the cavity of the jacket if inserted through the single opening and into the cavity, the cutting location being spaced apart from the single opening along the distribution cable at a position where the jacket is not breached,
- wherein the length of the distribution optical fiber protruding from the single opening in the jacket at the access location is at least 5/4 times the length of the single opening in the jacket at the access location;
- wherein the fiber optic distribution cable has a tubeless design such that the cavity immediately surrounds the plurality of optical fibers without intermediate tubes in the cavity surrounding the plurality of optical fibers.
2 more elements
A fiber optic distribution cable, comprising:
- a jacket defining an exterior of the fiber optic distribution cable, wherein the jacket defines a cavity therein and has an access location with a single opening formed in the jacket that extends to the cavity;
- strength members that provide tensile and anti-buckling strength to the distribution cable, wherein the strength members are disposed on opposite sides of the cavity and impart a preferential bend characteristic to the distribution cable;
- and
- a plurality of optical fibers extending through the cavity of the jacket, the plurality of optical fibers comprising a distribution optical fiber that extends through and protrudes from the single opening in the jacket at the access location,
- wherein the length of the distribution optical fiber protruding from the single opening in the jacket at the access location is at least 5/4 times the length of the single opening, and wherein the length of the distribution optical fiber protruding from the single opening in the jacket at the access location is about 7.5 centimeters or longer, and wherein the distribution optical fiber has an end that would extend to, but not beyond, a cutting location within the cavity of the jacket if inserted through the single opening and into the cavity, the cutting location being spaced apart from the single opening along the distribution cable at a position where the jacket is not breached.
2 more elements
A fiber optic distribution cable, comprising:
- a jacket, wherein the jacket defines a cavity therein and has an opening formed in the jacket that extends to the cavity, and wherein the opening is a slot;
- a plurality of optical fibers extending through the cavity of the jacket, the plurality of optical fibers comprising a distribution optical fiber that extends through and protrudes from the opening in the jacket, wherein the length of the distribution optical fiber protruding from the opening in the jacket is at least 5/4 times the length of the opening, and wherein the distribution optical fiber has an end that would extend to, but not beyond, a cutting location within the cavity of the jacket if inserted through the single opening and into the cavity, the cutting location being spaced apart from the single opening along the distribution cable at a position where the jacket is not breached, wherein the distribution cable is a ribbon cable, wherein the plurality of optical fibers are arranged in a stack of fiber optic ribbons;
- and
- strength members that provide tensile and anti-buckling strength to the distribution cable, wherein the strength members are disposed on opposite sides of the cavity and impart a preferential bend characteristic to the distribution cable.
