Largura de banda e taxas de dados
The terms bandwidth and data rates are often used interchangeably, but they are in fact very different if you work in the cabling world.

Rastreamento de cabos – até 600 V?
In a typical week, we get more questions on our Pro3000 Tone and Probe Series than any other product. That’s not surprising, as we sell a very large quantity of these testers.

Different Plugs, Same Test
Several vendors offer field-terminated plugs – both crimp style and modular insulation displacement. These plugs can be terminated to category twisted-pair cable to create patch cords or for use in a Modular Plug Terminated Link (MPTL) where horizontal cable is terminated on one end to a field-termination RJ-45 and plugged directly into a device, eliminating the outlet and patch cord at the end device.

TRC Results: Why You the Owner Should Care
In addition to individual link insertion loss and length results, a LinkWare Live report includes plenty of other useful information, including the date and time of the test, the test limit selected based on the application and the cable type. And there’s one other bit of information that as an owner and operator you shouldn’t overlook – the TRC verification results. While you may be focused on the individual link results of your test report, all your links could be suspect if the TRCs fail.

Lighting the Way for Visible Light Communications
Lately it seems that there is a lot of attention surrounding digital lighting and the ability to power and control LED lights over the network infrastructure using Ethernet-based technologies like TCP/IP and PoE. While the benefits of LED lighting are becoming well known – energy efficiency, reduced installation and maintenance costs, and integration with IoT – there’s yet another benefit looming on the horizon.

Série 101: Defina sua referência como um feiticeiro!
When it comes to testing fiber systems, connector loss refers to the loss of a mated pair of connectors – it’s actually impossible to measure a single connector. To test the loss of the first connector, it must be mated to a similar, known quality connector. That’s where Test Reference Cords (TRCs) come in.

Série 101: Cabos de conexão encadeados vs. sólidos
You’ve likely heard copper patch cords referred to as being constructed of either “stranded” or “solid” cable, but do you know the difference and which to choose when?
Just like the name implies, stranded four-pair cables are cables where each of the eight conductors of the four-pair cable are constructed of multiple “strands” of wires wrapped around each other, while solid cables are constructed with just one solid copper wire per conductor.

7 Reasons to Certify
Quando se trata de testar uma instalação de cabeamento, essencialmente há três opções, verificação, qualificação e certificação. Verification is great for troubleshooting as it will tell you if your cabling is connected correctly and can help you find breaks, connectors and splices. Qualification lets you know if your cable under test will support a specific application, making it great for small moves, adds and changes or determining if an existing cable plant can support an application (think 2.5/5GBASE-T testing over an installed base of Cat 6).
