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.
