Cerberis XG QKD System by ID Quantique is designed for production environments requiring standard key transmission rate and medium range interconnection. It securely distributes keys generated by QRNG to different locations, ensuring long-term confidentiality and integrity. Cerberis XG QKD System supports complex network topologies such as ring, hub and spoke, meshed, and star. It is controlled and monitored centrally and offers interoperability with major Ethernet and OTN encryptors. The system is suitable for enterprise, government, and telco environments, providing protection against brute force attacks and ensuring data security in a post-quantum computing world. The compact 19’’ rackmount 1U size provides high integration of QKD technology, and hot-swappable power supplies, cooling fans, and batteries ensure high availability operation. The system interfaces with major encryptor vendors offering a QKD-ready interface in their appliances and is compatible with the ITU recommendation for Dense-Wavelength-Division-Multiplexing (DWDM). The full QKD framework integrates with IDQ’s QKD management and monitoring framework, including the Clarion KX software suite, ensuring seamless integration into existing infrastructure.
