Abstract
Electrical cables and optical waveguides are disclosed as including an electrically insulative foam. The electrically insulative foam can coat at least one electrical conductor of the electrical cable. The electrically insulative foam can coat the optical fiber of the waveguide. The electrically insulative foam can also define a waveguide.
Claims16
An electrical cable comprising:
- a pair of electrical conductors having a first gauge size;
- an inner electrical insulator that is a monolithic structure that surrounds each of the pair of electrical conductors and extends between the electrical conductors over at least a majority of an overall length of the pair of electrical conductors, wherein the inner electrical insulator comprises a material that is foamed;
- an electrically conductive shield that surrounds the electrical insulator along at least a majority of an overall length of the electrical insulator;
- and
- an outer electrical insulator that surrounds the electrically conductive shield,
- wherein the electrical cable is configured to transmit data signals along the electrical conductors at a first frequency having a first level of insertion loss, and
- wherein the first level of insertion loss is no worse than a second insertion loss of an otherwise identical second electrical cable conducting data signals along the electrical conductors at the first frequency, wherein the electrical conductors of the second electrical cable have a second gauge size that is two sizes greater than the first gauge size and the inner electrical insulator of the second electrical cable comprises the material that is unfoamed and solid.
