Patent number: 9983376Abstract: High-data-rate interconnect cables are disclosed, wherein electrical data signals are transmitted in a conductor assembly made of a thin metal layer surrounding a cylindrical support member. The cylindrical support member can be a high-resistivity conductor or a dielectric, such as a glass optical waveguide that supports the transmission of optical signals.
