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.

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?
We all know that Category 6A is considered the highest performing twisted-pair cabling that supports 10 Gig speeds, and it’s been around now for more than a decade. So, you might be surprised to learn that Category 6 (now 17 years old!) continues to dominate worldwide sales of twisted-pair copper cabling. Although declining, even Category 5e that was introduced 20 years ago maintains a significant share of the market.
You’ve probably heard all the buzz about edge data centers. Don’t worry – this doesn’t mean you’ll be testing fiber links while hanging on the side of cliff. But while you might be testing in new spaces, edge data centers won’t really change what you’re already testing.
So what exactly is an edge data center, anyway? Let’s take a closer look.
We know we talk a lot about fiber cleanliness, but let’s face it, contamination of fiber endfaces is still the number one cause of failures – regardless of much we harp on the topic.
You’ve probably often also heard comments surrounding the fact that dust caps are really just dust collectors. Thankfully, there are plenty of manufacturers out there that get it and have responded with shuttered fiber connectivity.

Maybe you’ve been hearing some buzz recently surrounding single-pair Ethernet and a couple of new standards in development to support 10 Mb/s Ethernet. If you’re thinking that 10 Mb/s seems like old school, you’re probably not alone. After all, 10BASE-T has been around since the 1990s and is rarely even used as a signaling rate in today’s LANs. But this latest 10 Mb/s application is something different, and it has countless opportunities for a wide range of low-speed, low-bandwidth IoT devices – all over a single pair.
This week, Fluke Networks announced the FI-3000 Fiber Inspector Pro, designed for inspecting the end faces of Multiple Push-On (MPO) fiber connectors. We sat down with Carolyn Carter, the Senior Product Manager for Certification Tools to get the inside story on this new product.
Why an MPO Inspection Camera?
Many of you are likely seeing an increased use of singlemode fiber among your customers due to several benefits (primarily distance and bandwidth), connection to carrier networks and emerging singlemode applications in development.
When it comes to Tier 2 fiber testing, there are many smart people in our industry who can read an OTDR trace and pinpoint the type and location of a fault within the cable. And for those who might not be proficient in reading a trace, Fluke Networks’ OptiFiber Pro OTDR features advanced logic that automatically interprets the trace to provide a detailed and graphical map of events that includes the location of connectors, splices and anomalies.
