If you dropped by the Fluke Networks booth at the Fall BICSI Exhibition on Las Vegas this week, you had a chance to see three winners of the Cabling Installation and Maintenance Magazine’s Innovator’s Awards, and a possible candidate for a future award.

Sometimes, it seems like you need an extra hand when you’re testing. For example, when using our FI-3000 FiberInspector Pro MPO camera, you need a hand to hold the connector, a second to hold the camera, and a third to run the phone or Versiv unit and view the images. Most of the time, it’s not a big deal – for example, once you get the cable connected to the camera, you’ve got a free hand to operate the phone or Versiv. But it could help productivity in some cases if you had that third hand. Since we’re not in the prosthetics business,

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.

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.

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.

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).

Most of us are well aware that insertion loss budgets have gotten tighter as we have moved from 10 to 40/100 Gig for multimode fiber applications. One would think that we can’t say the same for singlemode applications that have historically meant larger loss budgets – 6.3dB for 100 Gig over singlemode (100GBASE-LR4) versus just 1.9dB for 100 Gig over multimode (100GBASE-SR4). But that’s no longer the case with new short-reach singlemode applications.

Installers have been punching down copper twisted-pair cable for decades and still do so for terminating cables to IDC towers on jacks, patch panels and connecting blocks. While the practice hasn’t changed, punchdown tools have come a long way, and you now have some options at your fingertips. So how do you choose? Let’s take a closer look.

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.
Many of these applications utilize twisted-pair cabling, and technology advancements now make it possible to deliver power to video displays simultaneously with these video signals over the same cabling. When it comes to deploying and testing cable plants required to support these AV systems, it’s important to understand best testing practices to ensure your customers get the perfect picture they expect.

It’s been a while since we’ve talked about OM5 multimode fiber, and despite its lime green color and being added to the ANSI/TIA-568.3-D standard in 2016, it hasn’t exactly been in the limelightbut it looks like that won’t always be the case.
