在布线承包商为新的远程工作场所采用基于云的免费软件时，LinkWare Live 会传递 5000 万个已上传结果
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.

如何测试您的以太网电缆是否支持 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.

测试 Profinet：基础知识
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.

何为增强型光束光缆连接器？
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.

光缆认证测试：你需要损失、长度值（有时需要反射率）
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.

混合铜缆光纤使用的考虑要素
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.

年终反射率
When Winston Churchill said that the holiday season is not only one of rejoicing but also of reflection, he didn’t know that 2020 would be the year that family gatherings are kept to a minimum and parties take place over Zoom and FaceTime.
