Abstract
A fiber optic cable having strength assemblies (30) adjacent a tube having at least one optical fiber therein, at least one of the strength assemblies including a strength member for imparting crush resistance to the cable. The strength member is generally coupled to a first jacket, and may be surrounded by a single jacket, or by an armor tape and a second jacket. The strength member may be disposed in a recess of the tube. When crush loads are applied to the fiber optic cable, the stresses created in the cable are advantageously distributed by strength assemblies (30) whereby stress concentrations and undue deflection of the cable in response to the crush loads are avoided. The arrangement of the cable components and strength assemblies (30) inhibits slippage and/or warping of the components under stress, and thereby evenly distributes the stress for preventing crush induced attenuation in the optical fibers.
