Cable Tracing – Up to 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.

Three New Innovative Products and Maybe a Future One?

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.

Prototyping a Future of “Hands Free” Testing

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,

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.

7 Reasons to Certify

Bezüglich des Prüfens einer Kabelinstallation gibt es im Wesentlichen drei Auswahlmöglichkeiten: Verifizierung, Qualifizierung und Zertifizierung. 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).

Short-Reach Singlemode Puts Reflectance on the Radar

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.

Know the Punch Line

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? Werfen wir einen genaueren Blick darauf.

AV über Twisted-Pair: Was ist zu testen?

Sei es für Video Conferencing oder digitale Anzeigen, viele unter Ihnen erhalten wahrscheinlich kundenseitige Aufforderungen, Kabelanlagen bereitzustellen, die audiovisuelle Systeme unterstützen.

Viele dieser Anwendungen nutzen Twisted Pair-Kabel, und technologische Fortschritte ermöglichen jetzt die gleichzeitige Versorgung von Video-Displays mit diesen Video-Signalen über die gleichen Kabel. Für Bereitstellung und Testen von Kabelanlagen, die für die Unterstützung dieser AV-Systeme erforderlich sind, muss man ein gutes Verständnis der besten und bewährtesten Testverfahren haben, damit die Kunden das perfekte Bild erhalten, das sie erwarten.
