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