Abstract

A fiber optic cable including at least one optical fiber and a strength member surrounding the optical fiber. The strength member can include a plurality of fibers disposed in a matrix such that the resulting strength member preferably has a modulus of elasticity of at least about 20 GPa and, more preferably, at least about 40 GPa. While the strength member can be an integral member, the strength member can be formed of at least two physically distinct portions in order to more precisely tailor the characteristics of the fiber optic cable. In this regard, the strength member can include a first strength member surrounding the optical fiber that includes a first matrix and a plurality of first fibers embedded within the first matrix, and a second strength member surrounding the first strength member that includes a second matrix and a plurality of second fibers embedded within the second matrix. The fiber optic cable can also include a release layer disposed between the optical fiber and the strength member to facilitate separation of the strength member from the optical fiber.
