Sceptre Link
The world’s most cost-effective, secure, and easy-to-integrate QKD solution

A Quantum Key Distribution (QKD) system, designed to work over existing optical fiber infrastructure, and supply symmetric encryption keys to connected devices for Quantum-Safe communication. The system includes an integrated Key Management System (KMS) enabling the deployment of ring, star, and mesh QKD networks with trusted nodes.

Sceptre Link is designed to operate alongside the optical network, by multiplexing the QKD optical channels onto the same fiber used by the client or using a dedicated dark fiber for quantum communication.

Why Choose Sceptre Link?

Significant Cost Savings:

Eliminates the need for an additional dedicated fiber network, leveraging existing infrastructure, resulting in significant cost savings in deployment and maintenance.

Unmatched Flexibility and Scalability

Allows any receiver to connect to any transmitter without the need for factory matching, enhancing flexibility in network configuration and scalability as requirements evolve.

Space-Efficient Rack Solution:

Our 1U design maximizes space efficiency while ensuring top-notch performance through integration with a Key Management System (KMS), freeing up valuable rack space for additional equipment.


Optical Fiber Compatibility:

Runs on dark fiber or multiplexed with DWDM, utilizing the existing fiber infrastructure for efficient operation.

Effortless Operation:

Designed for simple installation and management with no special skills needed, operating automatically on "power-on" after initial configuration.

Automatic Recovery:

Recovers automatically from various states, ensuring uninterrupted functionality, even during fiber replacement.

Clock Synchronization Channel Operates with a Single Pluggable SFP+:

One SFP+ module serves both the qTx and qRx links and supports any optical channel for synchronization.

Remote Monitoring and Control:

Secure access from anywhere with remote monitoring and control capabilities for enhanced manageability.

Interoperability Testing:

Integrated and tested with ETSI GS QKD 014 API compatible devices and Cisco SKIP, ensuring seamless interoperability.
