Abstract:
    The utility model discloses an interference unit installed in network switch, which comprises a plurality of isolation couplers, and an analog signal synthesizer. The input terminal of each isolation coupler is connected to different network line output terminals of each network line to obtain input signals. The output of each isolation coupler is connected to corresponding input terminal on the analog signal synthesizer. The output of the analog signal synthesizer is connected to the input terminal of a pair of idle line of each network line. The interference signal generated from the analog signal synthesizer is inputted to a pair of idle line of the network line to make it capable of being parallelly transmitter to another terminal following with the signals of another three pairs of network lines. If a person steals information from the internet line or other conducting line paralleled with network main line (such as telephone line and power line), actually what he/she steals is only mixed signals that are completely annihilated by interference signals, so as to achieve the aim of protecting the transmission of confidential information.
