Abstract

A drop cable includes a jacket having first and second opposing sides. The first side has a concave surface. At least one strength member is disposed in the jacket. An optical transmission component is disposed within the jacket and proximate the concave surface. The optical transmission component includes a plurality of optical fibers.

Claims (26)

1. An optical fiber drop cable, comprising:

a jacket having first and second opposing sides, said first side having a concave surface and said second opposite side being substantially planar, said first side of said jacket having a thinned portion defined by the concave surface;

a buffer tube disposed within the jacket and proximate the concave surface, the buffer tube having a plurality of optical fibers therein; and

first and second strength members disposed in the jacket at respective opposite sides of the buffer tube,

wherein said thinned portion is aligned with said buffer tube and

wherein an outside diameter of the buffer tube is greater than an outside diameter of the respective strength members.

2. The optical fiber drop cable of claim 1 , further comprising:

a ripcord disposed in the thinned portion of the jacket between the concave surface and the optical buffer tube.

3. The optical fiber drop cable of claim 1 , further comprising:

a toning wire connected to the jacket.

4. The optical fiber drop cable of claim 2 , wherein the toning wire is disposed in a sheath connected to the jacket by a thin web.

5. The optical fiber drop cable of claim 1 , wherein the plurality of optical fibers are arranged in a ribbon.

6. An optical fiber drop cable, comprising:

a jacket having two wide opposing sides wider than two other opposing sides, wherein one of the two wide opposing sides comprises a concave surface and the other side being substantially planar;

two strength members disposed in the jacket;

an optical transmission component comprising a plurality of optical fibers disposed within a buffer tube, wherein the optical transmission component is disposed between the two strength members and proximate the concave surface; and

a ripcord disposed in the jacket between the concave surface and the optical transmission component,

wherein the two strength members are disposed in thicker portions of the jacket than the optical transmission component and

wherein a diameter of the buffer tube containing the optical fibers is larger than respective diameters of the strength members.

7. The optical fiber drop cable of claim 6 , further comprising:

a toning wire.

8. The optical fiber drop cable of claim 7 , wherein the toning wire is disposed in a sheath connected to the jacket by a thin web.

9. The optical fiber drop cable of claim 6 , further comprising:

a plurality of strength yarns surrounding the optical transmission component.

10. The optical fiber drop cable of claim 9 , wherein the plurality of strength yarns block water.

11. The optical fiber drop cable of claim 6 , wherein the plurality of optical fibers are arranged in a ribbon.
