High-Speed Quantum Key Distribution Terminal QKD-POL1250-S series are QKD products with fully independent intellectual property rights owned by QunatumCTek. This series implement decoy-state BB84 protocol with polarization coding scheme to realize high-speed or long-distance quantum key distribution, and provide the quantum key that can't be eavesdropped or deciphered for the quantum secure communication network.
This series of products are 19-inch 4U standard rackable enclosure, and suitable for utilization in the equipment room of data communication. 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-S can be divided into two types: QKD-POL1250A-S (Transmitting in simplex mode), and QKD-POL1250B-S(Receiving in simplex mode). The two types can be connected together to execute QKD process, and provide secure quantum key.
QKD protocol：Decoy-state BB84 protocol with polarization coding scheme
Long distance key distribution: Adopt quantum signal transmitting or receiving module with working frequency up to 1.25GHz to support quantum key distribution over 100km optical fiber
Channel adaptation: Support real-time monitoring and compensation of polarization state
Quantum security: Against attacks such as photon beam separation attack, light blinding attack, double counting attack, Trojan light attack, seed light attack
High reliability of the platform: ATCA carrier-grade architecture, and redundant design with dual power supply, dual fans, etc
Easy maintained facility: Blade structure and Real-time Remote Monitoring
Convenient expandability: System compatible with third party and provide diverse configuration
