NewEdit OTDR traces right in your browser

The .sor editor for fiber OTDR traces

Open any standard .sor file, fix events, the trace and every header field, and export a valid .sor again. No install, no subscription. Pay only when you export.

From raw trace to clean report in minutes

Open a file, adjust events and the trace, validate, export. That is the whole workflow.

How it works

Three steps. No software to install.

1

Open your .sor

Drop the file into app.soreditor.com. The trace, events and all parameters appear instantly. Opening and editing are free.

2

Edit trace and events

Change loss, reflectance and distances and the trace follows. Shape the waveform, fix fiber IDs, locations and operator data.

3

Validate and export

Free validation checks the file before you pay. Export with 1 credit, then re-export the same file free for 24 hours.

Features

Everything inside a SOR file, editable

A full editor, not a viewer. Every change is written back as a standard SOR file your OTDR software can open.

Events

Events coupled to the trace

Edit an event and the curve changes with it. Move a splice, change its loss or reflectance, and the trace is reshaped to match.

  • Loss (LSA / 2PA), reflectance, attenuation and distance
  • Insert, move, delete or splice events out of the trace
  • Stored vs. measured values side by side

Waveform

Shape the trace with real tools

Select a zone with markers A–B and drag it up or down. Bridge a splice with matched noise, tilt, flip, copy and paste sections.

  • Drag-to-shift zones, with or without everything downstream
  • LSA splice, tilt, flip, copy / paste and matched noise
  • Original trace overlay and a reference .sor to compare

Analysis

Measure like on the OTDR

Zoom into any event and see the fit windows, peak height and noise. Re-measure every event from the trace in one click.

  • LSA fit lines and 2-point loss between markers
  • Reflectance from peak height and backscatter coefficient
  • Undo / redo for every change

Export

Valid files, every time

Before you pay, a free validation runs the exact export on our server and shows a full report. Exported files open in standard SOR viewers.

  • Checksums and derived fields recomputed
  • Unchanged blocks kept byte-for-byte
  • Headers: fiber ID, cable, locations, operator, supplier, acquisition
Valid files, every time

Nothing to install

Runs in Chrome, Edge, Firefox and Safari on Windows, macOS and Linux.

24 h re-export

One credit unlocks a file for 24 hours. Tweak it and export again at no cost.

Free validation

Check the result before spending a credit. You only pay for files you keep.

Compare with the original

The original trace stays as an overlay, so every change is visible.

Private by design

Encrypted connection. Your files are processed only to build the export and are not kept.

Under the hood

A real SOR engine, not an image editor

SOREditor reads and writes the binary SOR format itself. Every export is rebuilt block by block and validated before you download it.

Pricing

Pay per file. No subscription.

1 credit = 1 exported file. Opening, editing and validating are always free.

FAQ

Questions? Totally fair to ask.

Can’t find your answer? Write to us and we will reply as soon as possible.

What is a .sor file?
It is the standard file an OTDR saves after measuring a fiber, in the industry-standard SOR format. It contains the backscatter trace, the list of events (splices, connectors, fiber end) and header data such as fiber ID, locations, wavelength and pulse width.
What can I edit?
Practically everything: events (distance, loss, reflectance, attenuation, type, comments), the trace itself (shift zones, splice, tilt, flip, copy/paste, noise) and every header: general, supplier, acquisition parameters and fiber data.
How do credits work?
Opening, editing and validating are free. Exporting a file costs 1 credit and unlocks that file for 24 hours, so you can keep adjusting and export it again without paying twice.
Is there a free trial?
Yes. When you create an account and confirm your email you get 1 free credit, enough to export a complete file and check the result in your own software.
Which OTDRs are supported?
SOREditor reads SOR files in version 2 of the standard, the format written by most current OTDRs. Open your file for free: if it loads, it can be exported.
Do I need to install anything?
No. It runs in the browser at app.soreditor.com on Windows, macOS or Linux. A desktop computer is recommended for editing the trace.
I paid. When do I get my credits?
Usually in under a minute. Credits are linked to the email used at checkout, so pay with the same email as your account. If you buy first, they are added when you sign up with that email.
Are my files safe?
Files travel over an encrypted connection and are processed only to validate and build your export. We do not keep your traces; we only store a fingerprint to allow free re-exports for 24 hours.
Will the exported file open in my OTDR software?
Yes. Exports are standard SOR files with recomputed checksums, and blocks you did not change are copied as they were. The free validation shows the full report before you pay.
Is there a file size limit?
Up to 3 MB per .sor file, which covers even long, high-resolution traces.
