Social Distancing the LinkWare Live Way

While everyone has been working smart and social distancing, LinkWare Live surpassed another milestone with over forty million test results uploaded since it was launched back in 2015.  Last spring, we passed the twenty million mark meaning that LinkWare Live usage continues to grow exponentially, with total uploads doubling about every 12 months.

Мантра OM

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. Коммерческие

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

수평 케이블이 한쪽 종단이 RJ-45 플러그를 장치에 직접 연결하는 MPTL(Modular Plug Ended Link)은 콘센트와 장비 코드를 별도로 설치 하기 어려운 환경인 무선 액세스 지점과 보안 카메라에서 PoE 조명 및 비디오 디스플레이에 이르기까지 다양한 장치를 연결하는 데 점점 더 인기를 끌고 있습니다. 

디바이스 연결 옵션으로 ANSI-TIA 568.2-D에서 승인된 MPTL은 미국에서만 인기가 있는 것은 아닙니다. 하지만 여러분 중 일부는 TIA 표준을 따르지 않는 지역과 ISO/IEC 또는 CENELEC 표준에 대한 MPTL 테스트가 가능한지에 대해 질문하셨습니다. 짧은 답은 "아직은 아닙니다" 하지만 MPTL이 제대로 작동하는지 TIA 표준을 따르지 않는 지역에서도 확인할 수 있습니다.
