What’s On Tap?

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.

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

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.

Standards Update

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.

Тщательный анализ промышленных кабелей Ethernet

Last month, we published a blog about the various industrial Ethernet connectors including M-series and some new small form factor connectors like the iX and emerging single-pair Ethernet connectors. But what good is a connector designed to withstand the industrial environment without a cable that offers the same protection?

Проблемы промышленных Ethernet-кабелей — MICE

Industrial Ethernet is very sensitive to delays caused by dropped or damaged data frames (sometimes called packets).  Just a few dropped or damaged packets can cause a machine to shut down.  These problems are often intermittent and can be caused by harsh industrial environments.
