India-developed OpticSpectra 10G QKD combines high-capacity Free Space Optical communication with Quantum Key Distribution capability; system designed for links of up to 5 km
The system was unveiled at IMC 2026 in the presence of Shri Anil Kumar Lahoti, Chairman, Telecom Regulatory Authority of India (TRAI), underscoring the growing policy and industry interest around indigenous optical and next-generation secure communication technologies.
Shri Anil Kumar Lahoti, Chairman, Telecom Regulatory Authority of India (TRAI) said “India’s progress in indigenous optical wireless communication and quantum technologies reflects the growing capabilities of our domestic technology ecosystem. Innovations that bring together high-speed connectivity, secure communications and advanced photonics have the potential to contribute meaningfully to India’s digital infrastructure and technological self-reliance.”
High-Speed Optical Communication With QKD Capability
Free Space Optical communication transmits data between two points using highly directional beams of light rather than a physical fibre connection across the complete link. QKD is designed to enable the generation and exchange of cryptographic keys using quantum principles, adding a security-oriented capability to the communication architecture when correctly implemented and integrated.
By bringing the two technologies together, OpticSpectra 10G QKD is intended to support applications where both data capacity and communication security matter. NavTech sees potential use in telecom infrastructure, defence networks, strategic facilities and other mission-critical links.
For telecom networks, the system can support high-capacity optical connectivity where extending fibre may be difficult or time-consuming. For defence and strategic networks, the company is positioning the platform for communication requirements that place greater emphasis on secure key distribution, rapid deployment and network resilience.
Designed and Developed in India
OpticSpectra 10G QKD forms part of NavTech’s broader effort to develop advanced optical, laser and photonics-based communication technologies in India and move them from R&D into deployable systems for domestic and international markets.
The next phase of communication infrastructure will need to address capacity and security together. With OpticSpectra 10G QKD, our objective is to combine high-speed optical wireless communication with advanced key-distribution capability in an India-developed platform for telecom, defence and strategic networks,” said Hardik Soni, Co-Founder & CTO, Nav Wireless Technologies.
He further added “We want to take photonics technologies from Indian R&D into practical deployments. IMC gives us an important platform to demonstrate that transition from research to deployable deep-tech systems.”
QKD-Enabled Communication Gains Strategic Relevance
As communication networks become more data-intensive and security-sensitive, telecom and strategic infrastructure operators are evaluating technologies that can strengthen both capacity and protection of critical communications. NavTech believes QKD-enabled optical wireless systems can become one of the specialised building blocks within that broader transition. The company is developing its optical communication portfolio as a complementary layer alongside fibre, radio-frequency and satellite networks, with different systems addressing capacity, distance and security requirements.
