otsora vs FiberLens

otsora is a private, on-device otdr trace viewer for fiber-optic technicians. open a .sor file from anywhere — files, airdrop, email — and get an instant analysis: · fiber length, total loss, optical return loss · per-event splice loss, reflectance, slope · vendor-quirk handling for exfo, viavi, anritsu, yokogawa, jdsu export any single-core analysis as a pdf link report. cable pro (subscription) · analyze a multi-core cable in one pass — 1 to 288 cores · ranked repair locations across cores (splice clusters within 200 m) · per-core verdict + end-event classification (cut, crushed, mated pc, off-route…) · attach a kml/kmz route and see exactly where on the map to send a crew · watermark-free cable + per-core pdf reports · 7-day free trial, then $12 / month, cancel anytime private by design — traces never leave the device. no account, no upload, no telemetry.

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.
