A fiber optic cable includes an outer jacket, a first core tube positioned
within the outer jacket, and a first plurality of optical fibers
positioned within the first core tube, wherein the cross-sectional area of
the first plurality of optical fibers is less than 60 percent of the
cross-section inside area of the first core tube and wherein the length of
each optical fiber in the first plurality of optical fibers is between 1.0
and 1.001 times the length of the first core tube.
