• KEY FEATURES

   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, etc

   Easy maintained facility: Blade structure and Real-time Remote Monitoring

   Convenient expandability: System compatible with third party and provide diverse configuration

   Strict key randomness: Conform to the specification of the GM/T 0005-2012

   Support quantum channel WDM

• PRODUCT CATEGORY

   According to each facility’s function, this series of products can be divided into two types: QKD-POL1250A-S (Transmitting, Type-A), QKD-POL1250B-S (Receiving, Type-B)

• TYPICAL APPLICATIONS

   Long-distance (inter-city) quantum key distribution. The products have been practically applied in thousands of kilometers of quantum communication networks so far

   High-speed quantum key distribution under short-distance low-attenuation condition

Remarks：1.Optical fiber insertion loss is about 0.2dB/km

2.The above table shows the coding rate with gated APD detector
