Engineering explainers on φ-OTDR, OFDR, and DTS — how the physics constrains the system, where each technology's gain comes from, and how to select between them for a given asset. Written for engineers, not marketing.
Each article works through the physical constraints behind a sensing approach — where its performance ceiling comes from, what it costs to push past it, and the applications it genuinely fits.
Why conventional φ-OTDR hits a hard range ceiling, how coded pulse sequences trade time for energy without raising peak power, and when coding is — and isn't — the right engineering choice.

New articles are added as our engineering team works through field deployments.
We're starting with written technical articles. As readership grows, we plan to open per-article discussion threads so engineers evaluating or deploying DFOS systems can ask questions and compare notes directly. Until then, email us your questions, corrections, or topic requests — we read every message and may turn strong questions into future articles.
