What is OM1, OM2, OM3, OM4, OM5
multimode fibre?

Way back when, when fibre optics was simple, everyone talked about either multimode fibre or singlemode fibre. But these days things are a little more complex than that. There are different types of singlemode fibre and also there are different performance grades of multimode fibre.

In the two and a half minute video above we offer a quick, light-hearted, run through of the history of multimode fibre right up to the exciting developments with wideband multimode fibre. You’ll find out why it’s time to say goodbye to some old faithfuls and to understand what has changed with the latest new performance grade.

If you’d like more background detail than the video provides, then you can read more about the OM fibre categories in Richard Ednay’s blog here.

Is OM5 multimode fibre right for your application?

Or if you are ready to consider whether OM5 might be right for your application then have a read of Richard Ednay’s blog here where he drops in on a meeting between some of the characters that we use in the case studies on our training courses (such as the Certified Optical Network Associate programme) as they discuss whether it makes sense to deploy WBMMF in the ABC Bank’s next phase of datacentre expansion.

What can wideband multimode fibre and SWDM do?

If you’d like to understand how the twin technologies of WBMMF and SWDM were developed and get to know their capabilities and limitations then pop over to our main website and have a look at this video of a presentation Richard Ednay gave at a seminar.
