Abstract
A network tap monitors network information flow over a particular connection. By duplicating the signal and diverting a copy, the information flow can be analyzed, both in real time and without interference through the monitoring process. When the power to the tap is either turned on or off, however, the change in impedance in the tap's circuit can create an interference spike in the connection that interrupts the information flow. By reducing or eliminating the impedance change in the tap circuitry, such disruptive interruptions can be eliminated.
