유지가 이렇게 쉬웠던 적이 없습니다!

Keeping up with the industry is not easy. Changing standards, ways of working, technologies … Don’t worry – we have your back! We know it is sometimes hard to find the exact information you need to keep you moving forward here are some resources that will help you keep up and move ahead.

공구 벨트에 몇 개의 별이 있습니까?

We talk a lot about certifying copper cable plants using Fluke Networks’ DSX CableAnalyzer series certifiers, but voice, video and data deployments start with technicians having the right copper installation tools.

While Fluke Networks offers a wide range of copper and fiber installation tools designed to streamline the job and make you more productive, we thought it would be fun to take a look at our top 5 everyday copper installation tools from an Amazon.com point of view.

그림이 완벽한 AV 시스템

Whether it’s video conferencing or digital signage, many of you are likely facing requests from your customers to deploy cable plants that support audio-visual systems.

4 쌍 PoE로 업그레이드: 알아두어야 할 사항

수년 동안 VoIP 전화나 보안 카메라 같은 다양한 장치를 위해 이더넷 전원 장치(PoE)를 지원하는 배선 시설을 구축해 왔습니다. So far, up to 30 Watts is all you’ve been requested to support, but with the plethora of devices now able to take advantage of higher levels of PoE—like the latest 802.11ac Wi-Fi access points, digital displays and even desktop computers—your customers are starting to ask for four-pair PoE.

제가 2-코드 테스트 방법을 사용할 수 없는 이유는 무엇입니까?

Like the TIA and ISO, Fluke Networks promotes the use of the 1-cord method to set reference for fiber loss measurements. The 1-cord method is where a launch cord is attached to a light source and the other end to a power meter. A reference is then set (the power measured is defined as 0 dB). Next, the launch cord is disconnected from the power meter, but not the light source. Then the far end of the launch cord is attached to the cabling under test and a receive cord between the far end of the cabling under test and the power meter.

케이블 테스트 101: 하지만 표준은 0.75dB입니다!

We’ve covered fiber insertion loss testing in depth in many blogs, so by now you should know that it is the loss of signal that happens in a channel due to the length of the cable and any connectors, splices or splitters.

And hopefully you also know that estimating your loss budget involves adding up the loss of all of these components to make sure you’re within the loss limits specified by IEEE standards for the application you plan to run.

RJ45의 역사: 틀린 신원의 예

Our industry commonly uses the term “RJ45” to refer to the modular 8-position, 8-contact (8P8C) interface deployed for Ethernet over copper twisted-pair network cabling despite it pretty much being a case of mistaken identity.

But since the RJ45 name has stuck, we thought maybe we’d take a closer look at the history of this nomenclature and why to this day, it remains the de facto interface for twisted-pair Ethernet applications.

모두 캘리브레이션해서 좋은 시간을 가집시다!

Just like those who drive around long after the engine service indicator lights up on the dashboard, there are folks out there who have likely been putting off getting their tester calibrated despite the email or LinkWare Live notification from Fluke Networks.

너무 빠른 작별 인사? 모두 상대적 ...

You might remember that just about three years ago, the DTX CableAnalyzer™ was officially retired. Since its discontinuation, Fluke Networks has continued to offer technical support, repair and calibration for this tester that was once touted as the ultimate time saver and brought testing to a whole new level when it was introduced in 2004.

101 시리즈: LED 대 VCSEL

Since today’s high-speed fiber networks use 850-nm vertical-cavity surface-emitting laser (VCSELs) transceivers, some may be confused about why light emitting diode (LED) light sources are used for testing. Understanding the differences between these two sources will certainly shed some light.
