O Skinny em 28 cabos de conexão AWG

Over the past few years, several manufacturers have released 28 AWG patch cords that offer a smaller diameter to help improve airflow around active equipment and ease cable management at high density patching areas due to reduced congestion and a smaller bend radius.

Despite causing a bit of controversy in the industry since they were not originally recognized within ANSI/TIA cabling standards that require twisted-pair structured cabling to consist of 22 AWG to 26 AWG cables, these skinny patch cords continued to grow in popularity.

Projetando até os limites de aplicativo

When it comes to calculating loss budget, it’s important to know the loss limits for the given application as specified by industry standards. But if I really want to know how to design a system to these limits, you also need to know the loss of the specific vendors’ cables and connectivity you plan to deploy—and that can impact exactly which components you specify. This can make the task a bit tricky as not all cables and connectors are created equal.

Let’s take a look at a real-world example.

Feliz quinto AniVersiv™!

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).

Tchau, ruído!

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.

Olha, sem mãos!

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.

Quantas estrelas há no seu cinto de ferramentas?

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.

Atualizando para o PoE de quatro pares: O que você precisa saber

Há vários anos, você executa projetos de cabos compatíveis com o padrão Power over Ethernet (PoE) para diversos dispositivos como telefones VoIP e câmeras de segurança. 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.

Por que não posso usar o método de teste de 2 cabos?

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.
