OTDR viewer
An OTDR viewer that runs in your browser
Open a trace, find the events, measure a span with cursors and hand the file on, without installing anything. Works on macOS, Windows and Linux, from a tablet and from a phone.
No file at hand? The app has an "Open an example" button that loads a real measurement.
All features
Not a showcase of features, but the things used every day.
Files from any instrument
.sor in both versions of the standard, .msor, three dialects of .trc, .bdr, .TFW, .tst and files with no extension at all. The format is recognised by content, not by name.
Cursors and events
Two cursors, loss over a span both two-point and least-squares, automatic detection of reflective and non-reflective events, fibre end and ghosts.
Editing and saving
Metadata, events, trimming, recalculation by refractive index, and saving back to a .sor that opens in the instrument's own software.
There is nothing to download
There is nothing to install and no sign-up. The page opens by link: on somebody else's laptop, from a tablet, from a phone in the field.
What is free
Opening, viewing, measuring, editing, saving as .sor and sharing a link are free and need no account. Without signing in the workspace holds 96 files and the plot 8 curves; after signing in by email, 576 and 24; on Professional, 2048 and 48.
