Description
technical field [0001] The invention belongs to the technical field of optical communication transmission, and in particular relates to a quantum secret key distribution and PTN equipment fusion device and control method. Background technique [0002] Quantum communication has been proved theoretically to be absolutely safe. Because the quantum secret key distribution system uses single photon transmission, it has high requirements on the isolation of the transmission channel. As a result, the currently used quantum security communication network is to lay optical fibers separately and use trusted nodes for relay transmission. Quantum communication systems and optical communication systems cannot be effectively integrated, which is not conducive to the use of existing optical fiber resources to achieve engineering applications. [0003] With the continuous increase of communication traffic and the continuous increase of data bandwidth, the existing communication technology ...
