Abstract
An optical cable includes a plurality of deformable buffer tubes and an outer jacket surrounding the plurality of deformable buffer tubes. Each deformable buffer tube of the plurality of deformable buffer tubes includes a single flexible ribbon including a plurality of optical fibers. Each deformable buffer tube further includes an axial cross-section of the deformable buffer tube that includes the single flexible ribbon. The axial cross-section comprises an irregular shape.
Claims27
An optical cable comprising:
- a plurality of deformable buffer tubes, each deformable buffer tube of the plurality of deformable buffer tubes comprising
- a single flexible ribbon comprising a plurality of optical fibers,
- a buffer tube jacket comprising a first deformable material and surrounding the single flexible ribbon, and
- an axial cross-section of the deformable buffer tube that includes the single flexible ribbon, the axial cross-section comprising an irregular shape;
- and
- an outer jacket separate from respective buffer tube jackets of the plurality of deformable buffer tubes, the outer jacket surrounding the plurality of deformable buffer tubes.
(canceled)
An optical cable comprising:
- a central strength member;
- a plurality of buffer tubes disposed around the central strength member, each of the plurality of buffer tubes comprising a buffer tube jacket surrounding a single flexible ribbon, the buffer tube jacket comprising a first deformable material that is deformed plastically,
- wherein each single flexible ribbon comprises a plurality of optical fibers and a first longitudinal length, and
- wherein, for each single flexible ribbon, each optical fiber of the plurality of optical fibers is attached to an adjacent optical fiber of the plurality of optical fibers along a bond region comprising a second longitudinal length that is less than the first longitudinal length;
- and
- an outer jacket surrounding the plurality of buffer tubes.
(canceled)
An optical cable comprising:
- a rigid strength member;
- a deformable upjacket surrounding the rigid strength member;
- a plurality of buffer tubes disposed around the rigid strength member, each of the plurality of buffer tubes comprising a single ribbon comprising a plurality of optical fibers, wherein each of the plurality of buffer tubes including each corresponding ribbon comprises a first compressive modulus, and wherein the rigid strength member with the deformable upjacket comprises a second compressive modulus, wherein a ratio of the first compressive modulus to the second compressive modulus is greater than 1:1 and less than 1:20;
- and
- an outer jacket surrounding the plurality of buffer tubes.
