Passive network tap with digital signal processing for separating signals

摘要

A passive full-duplex bidirectional ZPL tap includes first and second network ports and tap ports. A signal separator is configured to receive a data stream from at least one of the first or second network ports and pass through the data stream and configured to obtain a first signal portion comprising at least the first signal component and obtain a second signal portion comprising at least the second signal component. A DSP stage is configured to substantially remove any second data component from the first signal portion and to substantially remove any first data component from the second signal portion. A first receive only Phy is configured to receive the first signal portion and provide the first signal portion to the first tap port and a second receive only Phy is configured to receive the second signal portion and provide the second signal portion to the second tap port.
