Abstract:
1. A passive full-duplex bidirectional ZPL network tap comprising: first and second network ports configured to operably connect with first communication cables, the first communication cables configured to carry full duplex bidirectional data signals comprising first and second signal components to and from the network tap device; a first tap port configured to operably connect with second communication cables; a signal separator configured to have a first node operably connected to the first network port and a second node operably connected to the second network port, wherein the signal separator is configured to pass through the full duplex bidirectional data signals from the first network port to the second network port and from the second network to the first network port, and wherein the signal separator is further configured to obtain a first signal portion comprising at least the first signal component and to obtain a second signal portion comprising at least the second signal component; a first receive only physical interface device (Phy) configured to be operably connected to the signal separator and to the first tap port so as to receive the first signal portion from the signal separator and provide the first signal portion to the first tap port; a second receive only Phy configured to be operably connected to the signal separator and the second network tap port so as to receive the second signal portion from the signal separator and provide the second signal portion to a second tap port; a first transmit and receive Phy configured to be operably connected to the first receive only Phy so as to receive the first signal portion from the first receive only Phy and provide the first signal portion to the first tap port; and a second transmit and receive Phy configured to be operably connected to the second receive only Phy so as to receive the second signal portion from the second receive only Phy and provide the second signal portion to the second tap port.
