The OM Mantra

Adopted by TIA, the nomenclature for multimode fiber found in the ISO/IEC 11801 standard includes the prefix “OM.”

Rather than the spiritual mantra you hear in yoga class, most sources in our industry state that the acronym OM comes from “optical multimode” which seems rather obvious. But when it comes to the various nuances of each type of OM, the differences aren’t quite as obvious.

Let’s take a closer look.

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. Commercial

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.

Testing Plug-Terminated Links—Internationally

The Modular Plug Terminated Link, or MPTL, where a horizontal cable run terminated on one end to an RJ-45 plug connects directly into a device, has become increasingly popular for connecting a variety of devices—from wireless access points and security cameras, to PoE lights and video displays—essentially wherever it’s deemed impractical or unsafe to deploy an outlet and equipment cord.

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.
