Лучшие методы трассировки кабелей

Although contractors spend a great deal of time and care designing and labeling cable installations, everyone who works on cabling runs into instances where they’re not sure where a cable goes. Perhaps the cable wasn’t labeled correctly when it was installed. Or maybe it was a technician’s "temporary" addition that has lasted for years. Learn which cable toners, identifiers, network cable testers and probes can help you cut the time you spend figuring out where that cable actually goes.

Добейтесь невероятных результатов с помощью 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.

Что происходит с однопарным 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).

Выбор между скрученным многожильным и одножильным кабелем

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: ваш незаменимый сетевой и кабельный тестер

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 жизненно важных правил безопасности при работе с волоконно-оптическими кабелями

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.

Основные сведения о полярности волокон

Полярность определяет направление потока, например, направление магнитного поля или электрического тока. В волоконной оптике полярность является направленной; световые сигналы проходят по волоконно-оптическому кабелю от одного конца к другому. Передаваемый сигнал (Tx) на конце кабеля оптоволоконной линии связи должен совпадать с соответствующим сигналом приемника (Rx) на другом конце кабеля.

Описание категорий кабелей Ethernet: Краткая история

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.
