High-speed Quantum Key Distribution Terminal

QKD-POL1250 series are high-speed QKD terminals launched by QunatumCTek with fully intellectual property rights. This series of products adopt decoy-state BB84 protocol and polarization coding scheme. The working frequency of the quantum signal transmitting or receiving is up to GHz level, and can meet the requirements of quantum key distribution over a long distance.

This series of products are 19-inch 4U standard rackable enclosure, and suitable for the engine room environments. With the superiority of high speed key generation rate and long distance transmission, QKD-POL1250 are mainly used in backbone network and intercity network.

QKD-POL1250 can be divided into two types: QKD-POL1250A (Transmitting in simplex mode), and QKD-POL1250B (Receiving in simplex mode). The two types can be connected together to execute QKD process, and provide quantum secret key, that cannot be decoded or eavesdropped, for the encryption service.

1、Optical fiber insertion loss is about 0.2dB/km;

2、Parameters in the form above represent the performance based on Gate-mode APD single-photon detectors. Products will perform better when based on Up-Conversion single-photon detectors.
