Abstract
A polymer-insulated crush-resistant high-strength optical waveguide fiber cable buffered by a braided layer of porous polytetrafluoroethylene fibers to provide strength, a low thermal expansion coefficient buffer, and strong environmental protection.
Claims9
An optical fiber cable assembly comprising:
- (a) a light-transmitting fiber core comprising an optical fiber surrounded by a cladding of lower refractive index than said fiber and a protective layer of higher refractive index than said cladding;
- (b) a braided expanded porous polytetrafluoroethylene layer surrounding said core;
- (c) an inner jacket of heat resistant polymer surrounding said braided fiber buffer layer;
- (d) a braided fiber strength member surrounding said inner jacket;
- and
- (e) an outer protective jacket.
