Abstract
A common mode signal attenuator includes a magnetic core, and a communications cable having at least one conductor adapted to transmit a communications signal. The communications cable is magnetically coupled to the core to form an inductive element having a magnetic flux path passing through the core. The inductive element has a volt-time capacity of at least about 0.0001 volt-seconds. An electrical transient suppression system includes an electronic device having a ground path, a communications cable, and a magnetic core. The communications cable has at least one conductor adapted to transmit a communications signal and is connected to the electronic device. The communications cable is magnetically coupled to the core to form a common mode signal attenuator having an inductance of about at least 10 times the inductance of the ground path. A method for reducing electrical transients in a communications cable includes magnetically coupling the communications cable to a magnetic core. The communications cable has at least one conductor adapted to transmit a communications signal. The communications cable and magnetic core are coupled to form an inductive element having a magnetic flux path passing through the core. The inductive element has a volt-time capacity of at least 0.0001 volt-seconds.
