We have successfully demonstrated an on-demand programmable hardware encryptor for optical networks enabled by the software-defined network (SDN) and tested its application in a quantum key distribution (QKD) use case. believe our proposed is unique way that it combines encryption algorithms with 100G Ethernet interface to provide high-transmission capacity flexible security. formed library con...

In this letter, a bidirectional symmetric 100 Gb/s/ $\lambda $ coherent passive optical network (PON) scheme with simplified unit (ONU) transceiver is proposed and experimentally demonstrated. the scheme, downstream signal generated i...
