Поздравляем с пятилетним юбилеем Versiv™!

To some, it may seem like just yesterday that Fluke Networks introduced the Versiv™ family of Cabling Certification Testers, especially for those who are still hanging on to their discontinued DTX CableAnalyzer™ (don’t forget that all service and calibration for DTX CableAnalyzers ends this June 30th).

Прощай, шум!

While labeling per the ANSI/TIA-606-B Administration Standards is considered best practice, let’s face it—labels don’t always happen or sometimes they’re simply not visible where you need them. Over time, cabling links may also have been reconfigured in the telecommunications room or the data center. And when you need to trace a cable or simply identify the other end among hundreds of copper links, a toner and probe can be your best friend.

Смотрите, никаких рук!

Did you ever have one of those days where your hands feel like two foreign objects that aren’t connected to your body or your brain? Yesterday started off as one of those days for me. It went something (maybe not exactly) like this.

The first mistake was my decision to carry too much stuff out to my truck while simultaneously balancing my coffee. It didn’t go very well. Not only was I now five minutes late from running back in to change my shirt, but now I had a cleaning charge to worry about.

Сколько звезд в вашем поясе для инструментов?

We talk a lot about certifying copper cable plants using Fluke Networks’ DSX CableAnalyzer series certifiers, but voice, video and data deployments start with technicians having the right copper installation tools.

While Fluke Networks offers a wide range of copper and fiber installation tools designed to streamline the job and make you more productive, we thought it would be fun to take a look at our top 5 everyday copper installation tools from an Amazon.com point of view.

Аудио/видеосистемы идеального качества

Whether it’s video conferencing or digital signage, many of you are likely facing requests from your customers to deploy cable plants that support audio-visual systems.

Обновление до PoE на четырех парах: что нужно знать

В течение нескольких лет вы развертывали кабельные системы, в которых применялась технология Power Over Ethernet (PoE) для целого ряда устройств: VoIP-телефонов и камер видео наблюдения. So far, up to 30 Watts is all you’ve been requested to support, but with the plethora of devices now able to take advantage of higher levels of PoE—like the latest 802.11ac Wi-Fi access points, digital displays and even desktop computers—your customers are starting to ask for four-pair PoE.

Почему я не могу использовать метод тестирования с 2 кабелями?

Like the TIA and ISO, Fluke Networks promotes the use of the 1-cord method to set reference for fiber loss measurements. The 1-cord method is where a launch cord is attached to a light source and the other end to a power meter. A reference is then set (the power measured is defined as 0 dB). Next, the launch cord is disconnected from the power meter, but not the light source. Then the far end of the launch cord is attached to the cabling under test and a receive cord between the far end of the cabling under test and the power meter.

История RJ45: ошибка идентификации

Our industry commonly uses the term “RJ45” to refer to the modular 8-position, 8-contact (8P8C) interface deployed for Ethernet over copper twisted-pair network cabling despite it pretty much being a case of mistaken identity.

But since the RJ45 name has stuck, we thought maybe we’d take a closer look at the history of this nomenclature and why to this day, it remains the de facto interface for twisted-pair Ethernet applications.

Откалибруем все устройства и хорошо проведем время!

Just like those who drive around long after the engine service indicator lights up on the dashboard, there are folks out there who have likely been putting off getting their tester calibrated despite the email or LinkWare Live notification from Fluke Networks.
