Abstract
A metallized optical fiber comprises: A) An optical fiber, and B) A conductive metal over and in contact with the optical fiber and having a thickness that is at least 0.15 times the thickness of the optical fiber. The metallized optical fiber can form a component of a hybrid optical fiber/coaxial cable, and it provides good protection against interference with the data signal traveling along the optical fiber from electrical current from an adjacent or near-by electrical conductor.
Claims15
A metallized optical fiber comprising:
- A) An optical fiber for data transmission, the optical fiber consisting of an optical fiber and a cladding coating the optical fiber;
- and
- B) A metal layer over, in contact with, and adhered to, the cladding of the optical fiber,
- the metallized optical fiber characterized by the metal layer having a thickness that is at least 1 times the thickness of the optical fiber,
- wherein the metal layer comprises at least one of copper, aluminum, a metal of the platinum group or metal of the precious metal group, and the metal layer is in the form of a strip that (i) runs along a longitudinal axis of the fiber and (ii) covers less than the entire surface of the optical fiber.
