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.

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.

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!

For those of you who got excited at the thought of happy hour when your customer requested a TAP, we thought you could use a little tutorial on these data traffic monitoring devices, the difference between passive and active TAPs, and some of the key considerations.

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.

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.

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.

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.

Since the last standards update, I represented Fluke Networks and attended the TR42 meeting in New Orleans and the SC25 WG3 meeting in Sydney Australia. The following are some of the highlights worth noting.
