ABSTRACT:
An information transmission system comprising a conductor operable to carry a desired information signal. A first tube substantially surrounds the conductor and a second tube substantially surrounds the first tube to define a substantially fluid-tight chamber therebetween. In another aspect, the invention provides an information transmission system suited to transmit information between a first electronic device and a second electronic device located a distance from the first electronic device. The system includes an information transmission line that connects to the first electronic device and the second electronic device. A conduit surrounds at least a portion of the information transmission line. The conduit defines a substantially fluid-tight chamber. A quantity of fluid is disposed within the chamber and a sensor is positioned to measure a parameter of the quantity of fluid. An indicator is operable to signal a breach condition in response to the measured parameter.
