FiberLens

Open, measure, and report OTDR .sor traces on Mac, iPhone, and Apple Watch — A/B markers, link-loss budget, fiber color codes, and one-tap PDF/Excel export.

FiberLens is a fast, native viewer and analyzer for OTDR trace files (.sor / .msor, Bellcore/Telcordia SR-4731). Open a trace, read every event, and produce a clean report in seconds — on Mac, iPhone, and Apple Watch.

WHAT YOU CAN DO • Open .sor and .msor OTDR traces and see the full event table — distance, loss, reflectance, and pass/fail status. • Interactive trace chart with pinch-to-zoom, pan, and A/B measurement markers that read out distance and dB instantly. • Link Loss (power budget) calculator — transmitter power, receiver sensitivity, safety margin, and allowable loss, seeded straight from the open trace. • Combine multiple same-wavelength traces into one continuous span across splices and connectors. • Fiber color-code locator — TIA-598 / IEC loose-tube and strand colors for any fiber number, with the full sequence legend. • Export polished PDF reports and Excel event tables for hand-off and documentation. • Configurable attenuation thresholds per fiber standard (G.652–G.657). • Settings sync across your devices via iCloud.

BUILT FOR THE FIELD FiberLens is a native Apple app — no logins, no accounts, no tracking. Your trace files stay on your device. Whether you're commissioning FTTH drops, troubleshooting a span, or documenting a splice job, FiberLens turns a raw .sor file into answers fast.
