The embodiment of the utility model discloses quantum signal is with classical multiplex signal and separate multiplexing device, through be connected the 2nd wavelength division multiplexer on the 2nd quantum signal and classical signal wavelength division multiplexer's optical signal output end, make and be quantum signal and synchronization signal through the smooth signal decomposition of the 2nd wavelength division multiplexer output, realized that the QKD terminal is sent through a port and received quantum signal and synchronization signal through different ports, the problem of current quantum signal and the same root optical fiber transmission's of classical multiplex signal the method less technique of application scope that can not send quantum signal and synchronization signal through the same port at QKD terminal and then cause is solved. 本实用新型实施例公开了种量子信号与经典信号复用与解复用的装置，通过在第二量子信号与经典信号波分复用器的光信号输出端上连接第二波分复用器，使得经第二波分复用器输出的光信号分解为量子信号和同步信号，实现了QKD终端通过个端口发出并通过不同端口接收量子信号和同步信号，解决了现有的量子信号与经典信号复用同根光纤传输的方法不能通
