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.

The 4th of July is always a time to reflect on our history, where we come from and the dedication of our founding fathers. But it’s also a time to look ahead, learn from past mistakes and progress towards a better future.
Our industry has a lot of history as well as traditional practices that we still use today simply because they work. But we also know that there are new ways of doing things, new parameters and new applications that are driving positive change.

With the addition of the modular plug terminated link (MPTL) configuration to the latest ANSI-TIA 568.2-D standard, and now end-to-end (E2E) configurations getting some attention in ISO/IEC standards (and likely soon TIA as well), you might be overwhelmed with the choices and be wondering what you’re supposed to test and when. Let’s take a look.

While the fact that a fiber link’s transmit signal (Tx) must match the corresponding receiver (Rx) at the other end makes perfect sense, ensuring proper polarity to ensure that this correspondence is maintained continues to cause plenty of confusion – especially when it comes to multi-fiber MPO connectivity where 12 fibers located in Position 1 through 12 at one end must each arrive at their corresponding position at the other end.

If you’ve turned on the news in the past couple of months, or if you live anywhere in the southern or central U.S., you’re well aware that natural disasters are at an all-time high – from recent tornadoes that have stretched from Texas north to Minnesota and east to Pennsylvania, to the swelling Missouri, Mississippi, Arkansas and Ohio Rivers and their tributaries causing flooding in nearly two-thirds of the country. In fact, 2019 has already seen more than 1000 confirmed tornadoes (more than in all of 2018), and more than half happened in the month of May.

Earlier this year, the IEEE released its 802.11ax Enhancements for High Efficiency Wireless (HEW) LAN standard, known commonly as Wi-Fi 6. This new advanced Wi-Fi application is positioned to theoretically deliver close to 10 Gig transmission through the use of eight spacial streams that each transmit at 1,2 Gb/s compared to Wi-Fi 5 (802.11ac) at just 866 Mb/s per special stream. It also has the ability to operate in both the 2,4 GHz and 5 GHz bands.

In response to the need for higher density in data centers, a couple of new fiber connectors have recently been introduced to the market. Because these connectors are new, test equipment with these interfaces has not yet been introduced, which presents some Tier 1 testing challenges and a shift from the traditional recommended 1-jumper reference method. Let’s take a closer look at these connector types and how to test them.
