ABSTRACT:
A connectionless signal detection device for conductive cables contains one or more bifurcated, wire-wrapped magnetic core assemblies positioned axially in an elongated alignment channel, allowing the device to accurately detect the transmission of signals or information on conductive cables using an inductive method. Each assembly section of the magnetic core assembly is wrapped with a conducting wire, with opposed assembly sections electrically connected in a bucking configuration, that is, the output side of one assembly section is connected to the output side of the opposing assembly section. The assembly sections either mate directly at their intersections or alternately operate with a dual gap. The elongated alignment channel opens and closes to allow positioning of the magnetic core assemblies concentrically about a conductive cable. The device operates in a connectionless mode and so is able to detect and monitor data transmission without physical, electrical, or logical interference to the conductive cable. The conductive cable may physically be any conductive cable type, including coaxial, twisted pair, or single conductor; electrically be operating at any level; and logically be transmitting using any protocol.
