ABSTRACT:
A compact, flexible, communications cable capable of electrical and optical signal propagation simultaneously is provided. The electrical signal is carried by coaxial inner and outer conductors of metal having suitable conductivity which surround and enclose a centrally disposed optical fiber conductor. The cable allows electrical signal propagation over a bandwidth from about 60 cycle D.C. or A.C. as well as radio frequency and microwave signals up to about 100 gigahertz without appreciable signal loss.
