An optical fiber cable having a plurality of optical fibers, at least one
tube surrounding the optical fibers and a plurality of strength members
positioned around the tube. A jacket surrounds the tube and the strength
members, where the ratio of polymer used to form the tube and the jacket
is at ratio of substantially 10:1 versus the strength members in terms of
cross sectional area at any point along the cable and where the Young's
modulus of the at least one tube and the jacket is substantially in the
range of 250-750 N/mm.sup.2.
