Everything you need to read a trace

📈

Real trace rendering

Parses the actual DataPts samples and draws the curve, verified point-by-point against pyOTDR.

🔎

Zoom & pan

Pinch or select to zoom into any span; a crosshair reads out distance and power as you move.

📐

A/B markers

Drag two markers along the fiber to measure distance, loss and attenuation between any two points.

🗂️

Event analysis

Every event with distance, loss, reflectance and a color status rated against your own thresholds.

🧵

Launch & receive cables

Mark launch and receive cable lengths; the chart shades them so the link under test stands out.

📄

PDF reports

Export a tidy A4 report with the summary, chart, events table and full file metadata.

Native on every Apple device

One app, built from a shared codebase. On Mac you get a full sidebar-and-table workspace; on iPhone and iPad the same trace, tuned for touch with pinch-zoom and a measurement-first layout.

  • macOS — sidebar, multi-column events table, PDF export
  • iPhone — compact event cards, swipe & pinch interactions
  • iPad — split layout with toolbar summary
  • Distance units: meters, kilometers, miles, feet

Speaks the OTDR format

FiberLens reads the Bellcore / Telcordia SR-4731 structure directly — both v1.x and v2.x files — including blocks most lightweight viewers skip.
