Abstract

A metallic current-carrying coaxial cable is connected by a plastic web to a cable holding light waveguides.

Claims

1. A communications cable, comprising:

a first tube containing a single coaxial current-carrying electrical conductor and no other electrical conductors;

a second tube containing a plurality of light waveguides and at least one strength member; and

,

a web extending between the first and second tubes, said web having a thickness narrower than half the outer diameter of the first tube or the second tube.

2. A cable as recited in claim 1 wherein the second tube and its contents are dielectric.

3. A cable as recited in claim 1 further comprising a waterblocking tape contained in the second tube.

4. A communications cable, comprising:

a first tube containing a single coaxial current-carrying electrical conductor and no other electrical conductors, and a tubular metallic shield disposed between the electrical conductor and the first tube;

a second tube containing a plurality of light waveguides; and

,

a web extending between the first and second tubes, said web having a thickness narrower than half the outer diameter of the first tube or the second tube.

5. A cable as recited in claim 4 further comprising a waterblocking tape held in the second tube.

6. A cable as recited in claim 4, wherein the second tube and its contents are dielectric.

7. A cable as recited in claim 6, further comprising at least one strength member contained in the second tube.

8. A cable as recited in claim 7 wherein the second tube and its contents are dielectric.
