A fiber optic cable includes an optical fiber, a strength layer surrounding the optical fiber, and a jacket assembly surrounding the strength layer. The jacket assembly includes a foam. A method for manufacturing a fiber optic cable includes mixing a base material, a chemical foaming agent and a shrinkage reduction material into a mixture in an extruder. The mixture is heated so that the base material and the chemical foaming agent form a foam with shrinkage reduction material embedded into the foam. An optical fiber and strength layer are fed into a crosshead. The mixture is extruded around the optical fiber and the strength layer to form a jacket assembly.
