Abstract
An optical cable includes a plurality of buffer tubes and an outer jacket surrounding the plurality of buffer tubes. Each of the plurality of buffer tubes includes a buffer tube jacket surrounding a plurality of flexible ribbons. The buffer tube jacket includes a first deformable material that has undergone deformation during formation of the optical cable to conform to an irregular axial cross-sectional shape of each respective plurality of flexible ribbons. Each flexible ribbon includes a plurality of optical fibers and a first longitudinal length. For each 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. The cable has a fiber density between about 5.0 and about 10 fibers/mm2.
