Simultaneous transmission of 20x2 WDM/SCM-QKD and 4 bidirectional classical channels over a PON

We report the transmission of 40 quantum-key channels using WDM/SCM-QKD technology and 4 bidirectional classical channels over a PON. To our knowledge the highest number of quantum key channels simultaneously transmitted that has ever been reported. The quantum signal coexists with classical referen...
