Ribbon Communications and CESNET Achieve Milestone in Quantum-Safe Optical Networks

Achieving Milestones in Quantum-Safe Optical Networking


In an era where data security is paramount, Ribbon Communications Inc. has proudly announced its successful completion of a proof of concept (PoC) demonstrating quantum key distribution (QKD) in collaboration with CESNET, the provider of the Czech Republic's national academic computer network. This impressive feat positions both organizations at the forefront of secure communication technology development.

This partnership is a culmination of efforts aimed at enhancing the security of communications within academia and research sectors. As Václav Novák, head of network infrastructure at CESNET, stated, "Our mission is to ensure the highest level of security for communication in higher education and research. This successful test builds on our long-term partnership with Ribbon and proves that quantum encryption can be implemented in real optical networks without sacrificing performance."

The Apollo optical networking system developed by Ribbon stands as a testament to innovation in this field. It provides optical encryption at the Layer 1 level, featuring virtually no latency and no additional overhead. This advanced configuration encrypts all payload and address information, allowing encrypted Dense Wavelength Division Multiplexing (DWDM) and Optical Transport Network (OTN) systems to transmit customer services seamlessly and without issues surrounding interoperability. The capacity for optical encryption is a potent tool in the fight against unauthorized access, enabling operators to implement security measures within their networks or offer added value services to their clients.

Christian Erbe, the head of EMEA sales at Ribbon, highlighted the significance of this milestone, asserting, "Quantum key distribution represents the future of secure networks. We are proud to support CESNET and provide a security solution that is virtually impervious and equipped to handle next-generation network threats."

As global reliance on secure and efficient communication continues to grow, the importance of innovations such as quantum encryption cannot be overstated. Ribbon Communications has established itself as a key player in this landscape, delivering secure cloud communication services and IP-related optical networking solutions for service providers, enterprises, and critical infrastructure sectors worldwide. Their commitment to modernization helps clients improve their competitive standing and business outcomes amidst today’s rapidly evolving digital environment.
