Relaxe com os recursos legais do Versiv™

It seems no matter where you live – the plains, the east coast, the UK or even our typically-cool Pacific northwest – the news is all about record-setting heat.  Worse, a lot of our favorite coping methods are unavailable – gas makes it too costly to go to the beach or mountains, pools are closed due to lifeguard shortages, and now you can´t even help yourself to an ice-cold Choco Taco.

What’s Happening with Single-Pair Ethernet?

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).

Choosing Stranded vs. Solid Wire Cable

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.

LinkIQ: Your Essential Network+Cable Tester

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.

5 Vital Safety Rules for Working with Fiber Optic Cables

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.

Noções básicas de polaridade de fibra

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.

Categorias de cabos Ethernet explicadas: Uma breve história

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.

Como testar um transceptor SFP e um cabo de rede

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.
