Today’s high-tech data centers form the digital heart of communication and commerce in our world. But every industry has its “remember when” stories, and there's no better time than now to tell them.

It’s been a few years since the Institute of Electrical and Electronics Engineers (IEEE) introduced the IEEE 802.3cg-2019 single-pair Ethernet (SPE) 10 Mb/s standards. There’s been a lot of industry activity and collaboration surrounding the technology since then — so we thought it would be a good time for an update on the status of Single-Pair Ethernet (SPE).

You’re probably aware that both shielded and unshielded twisted-pair copper cable comes in either stranded or solid wire versions. There are plenty of considerations when it comes to choosing one or the other, including standards, environment, application, and cost. Let’s take a look at the differences and considerations, so you can decide which cable type is right for your specific installation.

In a 2021 Network Field Report that surveyed more than 350 IT professionals, more than 70% said that network configurations happen daily, several times a week, or weekly. Nearly 50% of respondents also said they spend at least half of their time on reactive network tasks like troubleshooting, mapping, and configuration—leaving little time for strategic technology planning and digital transformation.

There are plenty of hazards to watch for when working on commercial and industrial networks. Fiber optic cable can seem safe; it doesn’t carry an electrical charge, and it’s not a heat source. More often it’s a lack of understanding of the real hazards of fiber optic cable that can be the most dangerous safety hazard of all.

Polarity defines direction of flow, such as the direction of a magnetic field or an electrical current. In fiber optics, polarity is directional; light signals travel through a fiber optic cable from one end to the other. A fiber optic link’s transmit signal (Tx) at end of the cable must match the corresponding receiver (Rx) at the other end.

Millennials who entered the workforce between 2003 and 2016 are accustomed to the digital era: high-speed internet access, smartphones, online everything. And while they’ve definitely experienced advancements in technology during their lifetime, they may not be aware of just how far copper Ethernet cabling has come to make it all possible. We thought we’d start off 2022 with a little Ethernet history lesson for the younger generation and a walk down memory lane for those of us that have been in the industry a bit longer than we’d like to admit.

Recently we have been getting questions about how to determine if an SFP (Small Form-factor Pluggable) transceiver is working. We refer to SFP generically here to represent a multitude of the various optical modules that are available. Fluke Networks fiber testers can be used to measure the light that is being put out by an SFP.

Contaminated connections remain the number one cause of fiber related problems and failures in data centers, campus, and other enterprise or telecom networking environments. But it’s not enough to just clean every fiber end face—there is no way to know if the end face is clean unless you inspect it.
