GN5-2 European NREN Interest in Fibre Sensing: Survey Results 2026

This document presents the results of a survey and targeted interviews conducted between September and November 2025 across the European NREN community to assess interest in and potential applications of fibre sensing. The findings indicate that interest is present but selective, with the strongest alignment in terrestrial infrastructure monitoring use cases, while scientific applications are primarily facilitated rather than operated by NRENs. Adoption is shaped by structural constraints and differing levels of maturity, suggesting that coordinated, shared approaches will be key to enabling scalable deployment of fibre sensing across the GÉANT community.
