PASSIVE TAP AND ASSOCIATED SYSTEM FOR TAPPING NETWORK DATA

摘要

A ZPL tap includes first and second network ports configured to carry the data stream to and from the network tap device. First and second tap ports may also be included. A signal separator having a first node connected to the first network port and a second node connected to the second network port is configured to receive the data stream from at least one of the first or second network port and pass through the data stream to the network port not providing the data stream and obtain while passing through the data stream a first signal portion substantially comprising the first signal component and a second signal portion substantially comprising the second signal component. A first receive only physical interface device (Phy) is configured to receive the first signal portion from the signal separator and provide the first portion to the first tap port and a second receive only Phy is configured to receive the second signal portion from the signal separator and provide the second signal portion to the second tap port.
