Abstract:
1. A system for transmitting data through a string of downhole components, each component having a first and second end, with the first end of one component connected to the second end of an adjacent component; the system comprising: a first communication element located at the first end of each component; a second communication element located at the second end of each component, wherein each communication element comprises a first contact and a second contact; a coaxial cable running between the first and second communication elements, the coaxial cable comprising a conductive tube and a conductive core within the conductive tube; and a first and second connector for connecting the first and second communication elements respectively to the coaxial cable, each connector comprising a conductive sleeve, lying concentrically within the conductive tube, that fits around and makes electrical contact with the conductive core, the conductive sleeve being electrically isolated from the conductive tube; wherein the conductive sleeve of each connector is in electrical contact with the first contact of the respective first or second communication element, and wherein the conductive tube is in electrical contact with the second contact of both the first and second communication elements.
