Abstract
A fiber optic cable having strength assemblies (,) adjacent a tube for imparting crush resistance to the cable, at least one of the strength assemblies including a strength member in contact with a tube having at least one optical fiber therein. The strength member is coupled to a first jacket, and may be surrounded 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 (,) whereby stress concentrations and undue deflection of the cable in response to the crush loads are avoided. Tight coupling and minimized gaps between the cable components in strength assemblies (,) inhibits slippage and/or warping of the components under stress, and thereby evenly distribute the stress for preventing crush induced attenuation in the optical fibers.
