What's new

What has been added to OTDR Master, what we fixed and what now works differently. Newest versions first.

  1. v2.13.2

    current

    Changed

    • Shared splice diagram pages have a clearer layout for the diagram, connection list and download buttons. PDF and PNG exports offer A4 or A3; a failed page load can be retried.

    Fixed

    • Recorded averaging time and acquisition range are preserved when importing several formats.
    • Event measurement boundaries are preserved when converting EXFO .trcx and .iolm files to .sor.
    • An incorrectly inflated acquisition range is fixed in some .sor files.
    • Older EXFO .oltsx files with manual power and loss measurements now open.
    • Completeness checks for Anritsu .trl trace lists count only successfully opened measurements.

  2. v2.13.1

    Changed

    • The cumulative loss tooltip now makes clear that the total includes the loss of the event itself.

    Fixed

    • Older EXFO .trc files that used to be refused now open.
    • Some Anritsu .trc files that used to be refused now open.
    • An ordinary .sor file with a .csor extension opens correctly.
    • Measurements from opposite ends match closely spaced events more accurately.
    • An unrecorded actual wavelength is no longer shown as 0.0 nm.
    • Long colour names no longer overlap neighbouring columns in splice diagram PDFs and PNGs.

  3. v2.13.0

    New

    • Averaging time shows on screen and in the report when the instrument wrote it into the file.

    Changed

    • The fibre colour code table can be saved as PDF after signing in by email.

    Fixed

    • Better automatic recognition of wavelength pairs.
    • Our own classification of damaged and empty .sor files.
    • Our own ORL calculation is improved.
    • The sign-in letter now arrives even through a brief mail server outage.

  4. v2.12.0

    New

    • OWL TrekII .otd files now open.

    Changed

    • OWL and Cisco are now named on the site among the makers whose files open.

    Fixed

    • The example trace no longer pairs up as a second wavelength with an opened file, on screen or in the report.
    • EXFO .trc files that used to be refused now open.

  5. v2.11.0

    New

    • In the splice sheet a joint can be a splice, a pass-through or a pigtail through an adapter. The APC or UPC connector is labelled on the diagram and in the crew sheet.
    • Splitter split ratio, patch panel port count and connectors are set right on the diagram, including connectors of single patch panel ports.

    Fixed

    • Traces in .tor show the line's total loss and length.
    • In the counter-trace picker the span length is shown in the file's units.
    • Multi-pulse .csor files open as one trace per pulse and save to .sor.
    • Older Ando .TRA files and EXFO files re-saved by third-party programs now open.

  6. v2.10.2

    Changed

    • Each trace in the file list now shows its length.
    • In the splice sheet, every spliced fibre is labelled with the cable it goes to. A started fibre is dropped by tapping anywhere off the fibre numbers.

    Fixed

    • A two-wavelength report takes the second wavelength from the same file, not from a neighbouring one.
    • Traces that used to be refused now open, including files from HiSilicon instruments.
    • Fluke LinkWare databases open in full, including CertiFiber Pro loss records.
    • Some .zip archives that used to be refused as a whole now open, with every trace inside.
    • A .sor file saved with a .trc extension opens as an ordinary trace.
    • On Yokogawa traces where the span markers were left over from an earlier measurement, the span is no longer longer than the fibre.

  7. v2.10.1

    Changed

    • If a trace was taken through a launch cable the instrument doesn't know about, you can mark where the launch cable ends. Distances, length and loss are then counted from its end, on screen and in the report. When the first event looks like the end of a launch cable, the app suggests it.
    • The splice diagram is more compact: the diagram itself is visible at once, the buttons sit in one row, and first-time hints are there.

    Fixed

    • EXFO .trcx files show the same events and link totals as the instrument itself.
    • Yokogawa traces with a single event in the table no longer show a span length of 0 m.

  8. v2.10.0

    New

    • A new tool: a splice diagram for a closure or a patch panel — a simple way to make a readable diagram. To send it there is a link with a QR code and the sheet as PDF and PNG, the connections table in Excel; Professional adds DXF and SVG drawings.
    • Files in the .EI format of CETC 41 instruments open.
    • Service news can come by email no more than once a month: a tick box at sign-in and in the account, unsubscribe by the link in any message.

    Changed

    • A new look for the My cabinet section.
    • An event can be added to a file where the instrument recorded none, and the report window warns that the sheet will carry no events.
    • The fiber color code page: more schemes with sources, up to 864 fibers, a Russian page with GOST.
    • Site pages and guides in Chinese, Spanish and Brazilian Portuguese.
    • Two wavelengths of one fiber pair up by acquisition time too, when the file name and fiber number say nothing.

    Fixed

    • TTI, JDSU MTS 6000 and Agilent E6000C traces open and read correctly.
    • A wavelength the instrument wrote in tenths of a nanometer reads correctly.

  9. v2.9.0

    New

    • A file from an instrument set to feet or miles shows distances in those units, on screen and in the report.
    • Yokogawa traces saved by the instrument as CSV open.

    Changed

    • When too many new files have been opened in a day, the app says so and offers sign-in. A signed-in account has a higher limit.
    • When a file cannot be read from disk, is empty, or the request does not reach the server, the app says which of these happened.
    • The AFL and Noyes page names the FlexScan FS300.

    Fixed

    • A large negative loss in the event table is no longer called a gainer.
    • Attenuation of sections with a very steep slope is read correctly.

  10. v2.8.0

    New

    • EXFO .iolm and Ando .TRA (AQ7210, AQ7220) files open.
    • A share link now carries a picture of the trace, visible in a messenger before the link is opened.
    • A trace can be saved as a picture.

    Changed

    • The site pages on formats and instruments are translated into Thai and Vietnamese.
    • New pages: SOR to Excel and opening a .sor file on Android.
    • The knowledge base has a new shelf, “What is this on my trace”, and guides to Grandway, Tribrer, OPWILL and NOVKER instruments.
    • Articles have a contents list at the side and a list of sources.
    • Event hints can be turned off with the cross.

    Fixed

    • Anritsu .trc files taken straight off a CMA4500 open.
    • In VIAVI files with a launch cable set, distance is counted from its end, as on the instrument.
    • Section loss and cumulative loss are more accurate.
    • Pairing of opposite-end traces shot with a launch cable at each end is improved.
    • The link length in Yokogawa files is read correctly.

  11. v2.7.2

    Fixed

    • A damaged .sor file is now called damaged, with advice to take it from the instrument again.

  12. v2.7.1

    Fixed

    • Minor fixes.

  13. v2.7.0

    New

    • Cable templates: the layout, the index of refraction and the limit are saved under the name of the cable type and filled in for the next drum.

  14. v2.6.0

    New

    • The service looks at the files you drop and suggests which ones can be put together as a pair.
    • The events of one fibre copy onto the other files of the cable: the distances stay, and each file works out the loss from its own trace.
    • The PON budget calculator has the XG-PON, NG-PON2 and GPON A, B and C classes, and the margin splits into ageing, repairs and temperature.
    • The link budget calculator has presets for link standards, connectors by polish, mechanical splices and multimode fibre.

    Changed

    • The site now names the instrument makers whose files open: more than thirty names on the features page and in the FAQ.
    • The Anritsu and EXFO pages name the instrument models.

    • Cursor readings are printed on the report sheet.
    • Acquisition settings and thresholds now show for files in the older version of the format.
    • Archives inside archives now open, up to three levels deep.
    • In a pair of counter-direction traces every event gets a mean, even if the instrument marked it from one end only.
    • The app reminds you that after signing in by email your work is there on any computer.

    Changed

    • New pages: NOVKER, AFL / Noyes, .tst files, embedded OTDRs.
    • When the connection is slow, the application says so.
    • .sor files from Gamma LUX OTDRs open.

    New

    • .wtk files from Wavetek MTS 5000 instruments now open.
    • An article on opening .wtk files.
    • While many traces open at once, a count shows how many are done out of how many.

    Changed

    • Archives of traces open faster.

  18. v2.2.0

    New

    • A cursor can be placed by typing its distance right in the readout line.
    • An event can be added to the table by typing its distance.
    • Cursors can be pinned: when you move to another file, they stay at the same distances.
    • A folder of traces can be dropped onto the window whole, subfolders included.
    • Dead-zone calculator: what the dead zone will be at the chosen pulse. The app links to it under the pulse width.

    • The report prints the fibre end without a loss, as on screen.
    • The far-end warning names where the curve went into noise.
    • A new page, in Russian: Gamma OTDR traces on a computer.
    • Knowledge-base articles are simpler and clearer.

  19. v2.1.1

    Changed

    • A new mark on the site, in the app and on the report sheet.
    • The example trace is clearer.
    • Double-clicking a file card leaves only its curve on the chart.
    • A file from your account can be hidden from the list on this computer.

  20. v2.1.0

    New

    • The app can be installed from Chrome or Edge: .sor and other trace files then open in it with a double-click.

    Changed

    • The CSV export carries figures at full precision rather than rounded as on the sheet.
    • A Fluke DSX copper test file is named as such instead of an unknown format.

  21. v2.0.0

    New

    • Projects: a site's files, thresholds and reports in one place, downloadable as one archive.
    • Cable summary report: a sheet for every fibre, a summary table and an Excel workbook. A large set is built in the background, and you can see how much is left.
    • Cable mode: fibres are checked against the drum's factory data, and the report prints as an incoming inspection sheet.
    • Your own report form: logo, company details, your own fields and signatures.
    • Batch edit: fibre numbers in order and file names from a template.
    • Reverse traces are found across the whole project, not only among the open files.
    • The report carries a QR code and a short address that opens the same traces.
    • The report language can differ from the screen language.
    • Event numbers sit above the plot, and a click on a number selects its table row.
    • Files in the list are numbered: go to a file by its number and page through the list with the arrow keys.
    • A file that is already in the list opens from there instead of uploading again.
    • Row edits in the event table can be undone in one press.
    • Signed in, you can download the report as a CSV table.
    • A manual for the app: every section on one page, with a search box and printing to PDF.

  23. v1.6.7

    Changed

    • The format pages are shorter and more accurate.

  24. v1.6.6

    Changed

    • The knowledge base now reads in Spanish and Portuguese: ten guides in each language.

  25. v1.6.5

    New

    • The file list now has a search box: by name and by the wavelength the instrument recorded.
    • One curve or all: keep a single trace on the chart and page through the fibres.
    • In PON mode every suggested splitter can be marked at once.

    Changed

    • The file list can be widened with the mouse, for long names.
    • Edits can be undone and redone from the keyboard.
    • A batch of files opens in name order.
    • The report prints the instrument’s make and model.

  26. v1.6.4

    New

    • .tst files from Fluke OptiFiber OTDRs on later firmware open.
    • A file can be renamed right in the line above the chart. It downloads under the new name, and the report uses it too.

    Changed

    • A page for owners of Fluke OptiFiber and OptiFiber Pro OTDRs: how to open a .tst file in the browser without LinkWare.
    • When the instrument wrote no event table but “Our analysis” finds events on the trace, the table switch is highlighted.
    • If the wavelength in the file name differs from the one the instrument recorded, the app warns you.
    • In the event table of EXFO files you see the marks the instrument itself made.
    • For EXFO files the parameters show the launch cable length and the span start where the instrument marked them.

    Fixed

    • When the connection to the server drops, the app says so in a line above the chart and carries on by itself once it is back.

  27. v1.6.3

    Changed

    • Pages for owners of Tribrer (T3, T3Lab), FIBERCLOUD (FC4000, 980TEK) and Grandway OTDRs: how to open the instrument's file in the browser with no software to install. The Grandway page is also in Vietnamese.

  28. v1.6.2

    Changed

    • The pages “Open a SOR file”, “SOR to PDF”, “OTDR viewer online” and “Open a TRC file” are now available in Spanish, Portuguese and Turkish.

  29. v1.6.1

    Changed

    • The first row of the table, at the instrument’s connector, is called “start of trace”, and pass/fail thresholds do not apply to it.
    • When the instrument placed a row before the start of the record, the table shows its distance with a minus sign, as the instrument does, instead of a dash. Rows come in the same order as in the instrument's table.
    • “Our analysis” is improved: it finds the fibre end more accurately and no longer overstates the loss of the first event after the instrument connector. Instrument rows are unaffected.

    Fixed

    • A .rar archive with nested folders now opens correctly.
    • The counter-trace picker is now displayed correctly.
    • For rows past the fibre end the instrument marked, the app no longer suggests taking a counter-direction trace.

  30. v1.6.0

    New

    • If the same curve is opened under two names, the app says so: “one measurement under different names”. In an acceptance folder this shows a fibre handed in twice.
    • File parameters now show the measurement direction and the launch cable when the instrument recorded them, and the instrument model when the file header leaves it blank. The report now fills in the direction and the fibre number.
    • For EXFO files the parameters show the reflectance threshold, and the totals show the span length where there used to be a dash.
    • In the PON view a row you have given a nominal to shows the word “splitter” next to the instrument’s event type.
    • The site has a page of example traces, where an example opens with one click, and an article on reading someone else’s OTDR report.

    Changed

    • Distances are counted from the instrument connector, as the instrument counts them, and no longer differ from its own.
    • In “Our analysis” the fibre end sits more accurately.
    • In the demo the “Next” button first shows the step on screen and leads on with the following press. The “What is here” shelf is now called “All features”.

    Fixed

    • A span loss the instrument could not have measured (8192 dB, for example) no longer reaches the totals.
    • In “Our analysis” rows past the span marker no longer disappear when the instrument marked no fibre end.
    • When you open a batch of documents instead of traces, one note under the list of names says what these files are and what to open instead.
    • The demo no longer closes by itself in the middle of a step.

  31. v1.5.0

    New

    • A guided demo: open an example and the app shows what it can do. An «It is an example» badge, a step-by-step tour — cursors and the 2P, LSA and 5P readings, an event row, pass/fail thresholds, the report — and a «What is here» shelf that replays any step.
    • The demo carries an example pair of counter-direction traces and an example PON network with a 1×4 and 1×8 splitter cascade: the pair average and the excess over the power split are visible on ready-made files, with none of your own.

    Fixed

    • In the PON view the «not measured beyond here» row no longer disappears when an instrument step stands next to it: the refusal keeps its own row in the table, and the span diagram shows a dashed line beyond it.
    • Cursor readings no longer cover the labels of overlaid curves in the measurement row.

  32. v1.4.3

    Fixed

    • Single-wavelength .msor files from VIAVI SmartOTDR open, and you can edit and save them like any .sor.

  33. v1.4.2

    Changed

    • The note on positions where an event sits on most fibres on the chart now shows in the ordinary view too, without “Our analysis”. In the ordinary view it counts the instrument’s rows, in “Our analysis” ours.
    • On a narrow window the file’s parameters are laid out in two columns when there is room: the panel is half as tall, and there is less to scroll.

    Fixed

    • When an archive opens only in part, the selection window names each file left out and the reason.
    • For an archive of traces from different fibres, the selection window no longer claims it holds one trace per wavelength.
    • Safari now shows the report sheet before you save it. Before, there was a blank white area in its place.
    • An impossible ORL value is no longer shown as a measurement.

  34. v1.4.1

    Fixed

    • Agilent E6000 files are now read in full: the event table, the acquisition settings and the wavelength.

  35. v1.4.0

    New

    • .zip, .7z and .rar archives open without unpacking when there are traces inside. The traces arrive as a list, and you can open them all at once or pick the ones you need. Handy on a phone, where there is nothing to unpack an archive with.
    • A cookie consent window. In Europe the analytics counters do not load until you press “Accept all”, and you can change your mind with the “Cookie settings” link at the bottom of any page on the site.

    Changed

    • The file list now holds 96 traces instead of 8, enough for a 48-fibre cable at two wavelengths. The chart still shows up to 8 curves at once, so each keeps a colour you can tell apart.
    • The file card in the list shows the wavelength, and for bidirectional .bdr files the direction as well: A→B or B→A.

  36. v1.3.0

    New

    • PON mode. You pick the splitter ratio in the event row, and the excess over the power split appears next to its loss. The mode is free.

  37. v1.2.0

    New

    • Reports in PDF and CSV, with form fields you fill in yourself.

  38. v1.1.0

    New

    • A Share button. The link works for two weeks: the recipient opens a copy of the trace with your edits and can edit that copy without touching yours.

  39. v1.0.0

    New

    • The service moved to otdrmaster.com, and old links to otdrmaster.ru keep working.
    • The site opened in fifteen languages, Turkish among them, and the app speaks the same fifteen.
