Le mantra OM

Adoptée par la norme TIA, la nomenclature de la fibre optique multimode de la norme 11801 ISO/IEC contient le préfixe « OM ».

Au lieu du mantra spirituel que l’on entend pendant les cours de yoga, la plupart des sources de notre industrie indiquent que l’acronyme OM signifie « multimode optique » (optical multimode, OM), ce qui semble plutôt évident. Mais lorsqu’il s’agit de discerner les différentes nuances de chaque type d’OM, les différences ne sont pas aussi évidentes.

Nous allons y jeter un coup d’œil.

What are all those specialty cords you use?

I was recently asked by a customer, to whom I was demonstrating a Fluke Networks OptiFiber® Pro OTDR and CertiFiber® Pro OLTS, why do you need all those specialty test leads to make measurements?  Why can’t I use patch cords?  We often take the understanding of such things for granted, so let’s take an in-depth look at the various accessory cords you need to make measurements accurately with our testers.

But I can’t get to the far end!

There are often times when you have to test a fiber link, but you can’t access the far end.  One of our customers, for example, was required to test fiber links to offshore wind platforms.  Unfortunately, in order to set foot on a platform, the technician would need to complete three days of safety training.  Three days training, lost time and all to test just a pair of fibers running to each tower.

Get Reel Before You Install!

It’s obvious why you might want to test reel of cable before you commit your time and resources to installing it. While it would be nice to think that every reel of cable coming out of the factory is in perfect condition, that’s not always the case. Furthermore, what’s not to say that the reel wasn’t damaged during shipping and handling? Just imagine testing the cable plant after installation only to find out that the cable is faulty—now that’s time and money lost!

Electromagnetic Interference Mitigation in Industrial Ethernet Cabling

While standard and Industrial installations of Ethernet share many of the same characteristics, such as frame sizes, signal levels and data rates, there are significant differences as well. One of these is the physical environment in which the cabling system operates.

Industrial Ethernet vs. Publicité

We all know that Ethernet is the de facto physical layer communication protocol for data transmission between devices in a local area or wide area network. It has evolved over the years to deliver higher levels of performance while maintaining backwards compatibility, reliability and relatively low cost, which is why it has maintained its popularity.

The Ins and Outs of Third-Party Certification

Likely you’ve noticed that cable, patch cords and connecting hardware from reputable manufacturers are promoted and labeled as third-party certified, verified or listed. Third-party certification is an extremely important part of our industry, giving you peace of mind that your chosen manufacturer has independently determined that their products comply with industry standards.
