Overview
The HORIZON-JU-SNS-2025-01 grant is part of the Horizon Europe program, aimed at funding Research and Innovation Actions focused on developing advanced optical access networks and packet optical network architectures for 6G integration. The official call opened on May 22, 2025, and submissions are due by September 18, 2025. This grant emphasizes the creation of energy-efficient solutions with a total budget of approximately EUR 128 million dedicated to supporting these research efforts.
Eligible applicants include legal entities from EU Member States, Associated Countries, OECD countries, and Mercosur countries, while excluding entities from non-eligible countries such as Russia, Belarus, and certain areas of Ukraine. Applicants must adhere to specific conditions, including the necessity for a gender equality plan for public bodies, research organizations, and higher education institutions.
The funding type available is a grant, specifically a Research and Innovation Action which provides non-repayable funding. The participation in projects necessitates collaboration among multiple partners, highlighting partnerships between industry and academia. The targeted sectors include Information and Communication Technology, with an emphasis on 6G architecture, optical networks, and the integration of advanced technologies like AI and quantum networking.
Funding amounts vary by project stream, typically ranging from EUR 8 million to EUR 21 million, with notable grants such as EUR 15 million for certain topics and indicative numbers of grants per topic generally being low-moderate, which suggests competitive selection.
The call process follows a single-stage submission model, which allows for streamlined evaluation. However, success rates are not specified, and co-funding requirements appear to be non-existent as Horizon Europe typically covers 100% of eligible costs for RIAs.
Overall, this initiative aims to advance the capabilities of future networks by fostering innovations in optical access and packet optical architectures, enhancing EU leadership in telecommunications, and supporting sustainable network solutions while promoting collaboration among diverse stakeholders in the telecom ecosystem.

Detail
The EU's Horizon Europe program, under call HORIZON-JU-SNS-2025-01, is offering funding for Research and Innovation Actions (RIA) aimed at developing higher speed optical access networks and future end-to-end packet optical network architecture for integration with 6G. The call, titled "Higher Speed Optical Access Networks and future end-to-end Packet Optical Network Architecture in 6G," falls under Stream B-03. The submission session is now available since May 22, 2025, and the deadline for submissions is September 18, 2025, at 17:00 Brussels time.
The expected outcome of the projects funded under this call is the availability of advanced optical access networks and packet optical network architectures that can be integrated with 6G. These systems should be applicable across various domains, providing energy-efficient data transport for very high throughput rates. Key targets include:
Integration of high-performance and efficient passive optical networks (PON) based on technologies like PON or DWDM, and adaptive multiband optical transmission, including xhaul, into the 6G architecture.
Integration of photonics and wireless systems, including sensing capabilities.
Development of protocols for future end-to-end packet optical network architecture, considering adaptive multiband optical transmission and open, disaggregated optical networks.
AI-enhanced green optical networks and systems, AI-enabled optical network automation, and optical sensing for environment and networks.
Enhanced trustworthiness through security enhancements and increased resilience.
The proposed activities should address both research and innovation issues for low Technology Readiness Level (TRL) topics and plan for demonstrations of end-to-end architecture, particularly for very wideband use cases, to showcase overall energy consumption.
The scope of the call focuses on:
Higher speed optical access networks and future end-to-end packet optical network architecture in all network domains.
