Abstract
An optical fiber cable comprising 200 micrometer (μm) optical fibers (fibers with an outer diameter of approximately 200 μm) that are located within buffer tubes. This permits fiber packing densities of 3.8 fibers/mm2 or higher. The buffer tubes have wall thicknesses (tbuffer) between approximately 7.5 percent (7.5%) and approximately 30% of the buffer tube's outer diameter (ODbuffer), and a Young's modulus that is between approximately 750 mega-pascals (MPa) and 2,200 MPa, thereby providing the necessary structural integrity to resist kinking yet maintain flexibility.
