ABSTRACT:
The principles of the present invention relate to passive full-duplex bidirectional Zero Packet Loss (ZPL) network taps that include single, dual, or dual differential couplers that are placed in the communication path between two network devices that communicate using a full-duplex bidirectional data stream that include a first and a second data component. The bidirectional couplers are configured to at least partially obtain a second data stream that includes at least the first data component and to obtain a third data stream that includes at least the second data component. In some embodiments, the bidirectional couplers may include a signal separation module or stage that is configured to further separate the first and second data components.
