SNR · SNR-OTDR-01 · SNR-OTDR-01N

Open an SNR OTDR file on your computer

.sor files from the SNR-OTDR-01 and the SNR-OTDR-01N open in the browser. You see the trace, the event table and what the instrument recorded about the shot. There is nothing to install, and any operating system will do.

Open an SNR file

Try a file from another SNR model too. If it does not open, send it to us: a new format usually arrives with the next release.

The application window with a trace open. The file name on top, and beside it the totals: optical length, span loss and ORL. Below that, the chart toolbar with the wavelength and pulse width, then the OTDR trace across the whole range with vertical event marks, the overview strip under it, and a line telling how the cursors are placed.

What you will see

Both models write an ordinary Telcordia .sor. We read all of it, the way the instrument wrote it.

The trace and its events

The trace with zoom and cursors A and B, 2P and LSA readings between them, and the instrument's event table: connectors, splices, the fibre end, with loss and reflectance.

1310 and 1550 nm together

The instrument saves each wavelength as a file of its own. Open both and the two curves go onto one chart, each in its own colour.

A whole site at once

Open one trace, a folder of files from one ODF or a .zip archive. The list keeps every file, and you switch between them with one click.

You do not need a Windows program

The SNR-OTDR-01 and the SNR-OTDR-01N come with different PC programs, one for each model. Both run on Windows only, and each has to be installed first.

Here there is nothing to choose. A file from either model opens by link in the browser: on Windows, macOS and Linux, on a tablet and on a phone. You do not need an account. You make the PDF report and a link for a colleague in the same place, free.
