Abstract
A coated optical fiber adjusted to operate at a predetermined temperature range. The coated fiber includes an optical fiber, a first polymer coating generally concentrically surrounding the optical fiber and a second polymer coating generally concentrically surrounding the first polymer coating, wherein the first polymer coating includes substantially no coefficient of thermal expansion stresses when the optical fiber is placed at a lower end of the temperature range.
