FiberLens

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.
