285 EoR toolkit and seamless integration with their workflow. Provider competency with DFOS also matters because performance and usability are strongly influenced not only by hardware/technology ability, but also by TSF domain expertise, and end-to-end workflows. For TSFs, a competent solution provider should be able to partner with the Operator and EoR to co‑design: (a) a consequence‑based fibre layout (crest/toe/drains/abutments and optional boreholes), (b) commissioning tests that verify sensitivity and localization, and (c) dashboards and alerting that translate distributed signals into clear operational states. In addition to hardware, a modern DFOS platform provides advanced software capabilities that support geotechnical monitoring operations. This includes edge acquisition for remote sites, user configurable processing chains, and remote portals/APIs for integration into existing monitoring systems. This shifts the adoption barrier from ‘can we measure?’ to ‘can we operationalize and govern the data?’, enabling repeatable deployment across portfolios as costs trend down and interpretability improves. With the right implementation framework and collaboration between TSF operators, technology providers, and EoR, these capabilities will be adopted and applied to TSFs.
