Open an Anritsu OTDR file in your browser

.trc in the T5 format, its successor T6, and the extensionless files the Anritsu software writes all open right here, without TraceView and without Windows.

Open an Anritsu file

T5 came to Anritsu together with the NetTest and CMA4000 instruments, so the same format shows up under both names.

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 we actually read

Two revisions of one format, T5 and T6: their signatures differ by a single character, and the insides differ altogether.

`.trc` in the T5 format

The format of NetTest and Anritsu CMA4000 instruments. The samples sit in our corpus, with distances checked against the vendor's own output.

T6: the next revision

The next revision of the same format, the CMA5000 instruments. Its signature differs from T5 by a single character, and the inside is built differently.

A file with no extension

Anritsu software often saves a measurement with no extension at all. Inside it is ordinary Bellcore: we recognise it by its contents rather than its name, and open it as .sor.

Anritsu trace viewer download: TraceView files in a browser

There is nothing to install and no account needed. The page opens by link on macOS, Windows and Linux, from a tablet and from a phone.

What we do not read yet

Anritsu instruments live long, and the early series have containers of their own. Those we do not open yet.
