RP Fiber Calculator – Get it Here

Download and Installation

This software works on computers running under Microsoft Windows. (Any Windows version since Windows XP should do, but not within a virtual machine.) It's very simple: just download the installation file by clicking on this button:

Then run this file to get the software installed.

If you use Windows 8 or 10 (or Internet Explorer on other systems), you might see a message like “Windows SmartScreen prevented an unrecognized app from starting ...”. You can then press on “More info”, verify the publisher (RP Photonics Consulting GmbH) and choose “Run anyway”, but only if you are sure that you downloaded the program from our website, i.e., you got the original software.

If you have any problem with the download or installation, we will be grateful to learn about it via an e-mail. (That applies also to users of the free version.)

We assure you that we have not intentionally or knowingly equipped our software with any hostile functionality, for example for damaging anything on your computer, infecting it with malware or violating your privacy. However, we obviously have no control over what modified (possibly infected) software might be illegally offered for download on other websites. And we cannot take responsibility for criminal attacks from third parties if these cannot be prevented by us despite acting with due care.

Update History

Here we keep you informed on the released versions. (We occasionally offer updates when we identify and remove bugs or add new features.) The software also occasionally displays the table below, and offers to download an update if it is available.

License Conditions

The installation of the software requires you to accept our license conditions. These are very generous; the essentials are:

  • You can use that software even for commercial purposes without paying anything.
  • We do not require you to register with us as a user.
  • You are not allowed to give the software to other persons or institutions. Every user should download it himself from the RP Photonics website. This is to make sure that everyone gets the original software (not one with malware added by another party!) and also the latest version.
  • We fully respect your privacy. Our tool will only occasionally check for available updates or other notices on our server, and allows you to get further information in your web browser. We will not try to identify the users of our free software.

Your feedback is welcome – for example, if you report bugs or suggest improvements. Please understand, however, that we cannot offer further technical support for a totally free product. Of course, you may obtain paid technical consultancy from RP Photonics.

Enjoy it and Tell Others!

What we hope is

  • that you will enjoy this convenient tool,
  • that you will tell others about it (e.g. via e-mail, websites, social media), who can also profit from it, and
  • that you will consider to purchase some of our other software products – namely the extremely powerful and flexible RP Fiber Power software, with which one can do much more.

Another offer: we have interesting newsletters which you can subscribe to. One of them (the RP Photonics Software News) is specially on software issues.
