Cabling Chronicles’ 4th of July Reflections
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.

Channel, Permanent Link, Patch Cords, MPTL, E2E… Oh My!
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.

Getting Polarity Right the First (or Second) Time Around
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.

Disaster Due Diligence
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.

Wi-Fi 6 is Here! So Now What Will You be Testing?
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.

With New High-Density Fiber Connectors Comes Tier 1 Testing Challenges
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.

You Too Can Transform How You Do Business
Last week, Fluke Networks announced that the number of results uploaded to our LinkWare Live cloud service has exceeded 20 million. If you’re one of the many who contributed to the doubling of total results over the past year, you’ve already witnessed the benefits and cost savings of managing cabling certification jobs anytime, anywhere, with anyone on any device.

What is (+All) and When Should I Choose It?
When it comes to testing twisted-pair cabling, there are some key testing parameters required for certifying a permanent link to industry standards—parameters like insertion loss, NEXT, PSNEXT, ACR-N, PSACR-N, ACR-F, PSACR-F and return loss. And when it comes to testing Cat 6A (or Class Fa for ISO11801 standards), we also have PSANEXT and PSAACR-F for alien crosstalk testing.

What Ever Happened to the Mechanical Splice?
When it comes to joining two or more optical fibers together, fusion splicing whereby cleaved fibers are aligned and fused by an electric arc provides the lowest loss and strongest, most reliable joint.
While mechanical splice connectors have come a long way and are an ideal field termination method for connectorizing fiber, we rarely hear much anymore about mechanical splicing as a means for joining fibers along a link – even though it eliminates the need for expensive fusion splicing equipment.
So what ever happened to the mechanical splice anyway?
