Служба LinkWare Live передает 50 млн результатов, загружаемые подрядчиками кабельных сетей, которые используют это бесплатное облачное программное обеспечение на новых удаленных рабочих местах

One result of the COVID-19 pandemic was the acceleration of digital transformation in business, government, and education. While many organizations were already on the path to going digital, the pandemic created a critical need to move ahead more quickly than originally planned.

Как проверить, поддерживают ли кабели Ethernet технологию PoE

Power of Ethernet (PoE) is combining power and data communications in a single cable. As it’s become more and more popular, there are a huge array of devices that source and consume power and data through the same cable. Do all Ethernet cables support PoE? No, they don’t. So, how can you be sure the cables you selected can support PoE operation? Fluke Networks’ Jim Davis walks though the steps to make sure your cabling is ready to support PoE operation using an DSX CableAnalyzer.

Тестирование Profinet: Oсновы

We all know by now that Ethernet has infiltrated the factory floor as the communication protocol of choice for exchanging data between devices and controllers, with applications like Modbus, EtherCat, EtherNet/IP and Profinet that are all based on Ethernet. The two leading applications—EtherNet/IP and Profinet together account for about 60% of the market, as both excel in supporting deterministic communication for real-time data and control.

Что такое оптоволоконный разъем Expanded Beam?

In the premises and data center infrastructure world, most of us are familiar with typical fiber connectors like duplex LC, SC and ST connectors and multi-fiber MPOs. Perhaps you’ve also heard about expanded beam fiber connectors or have encountered a scenario that requires them.

In case you aren’t familiar with these connectors, their applications and testing considerations, we thought we’d help you “expand” your knowledge.

Сертификационное тестирование оптоволоконных кабелей: Все, что вам действительно нужно — это потеря, длина (а иногда и отражение)

As data speeds increase and new fiber applications emerge, there has been some confusion surrounding fiber testing parameters and whether insertion loss testing is enough to guarantee support for high-speed applications.

Other than new short-reach singlemode applications that are more susceptible to reflections and therefore take connector reflectance into consideration, insertion loss testing, length and polarity are really all you need for Tier 1 certification testing.

Рекомендации по использованию гибридного медно-волоконного кабеля

In a previous blog, we covered what to do when you need to connect a device that is located beyond the 100-meter distance requirement and described four ways to address the problem—a new TR, the use of an extender device, extended-reach copper cable and fiber.
