케이블링 산업 현황
테스트 코드를 확인할 때 "긍정적인 손실"을 얻는 이유는 무엇입니까?
Verification of test reference cords is easy, right? Yes, usually…but not always. After the power meter is set to 0 dB via the reference procedure, the loss of a mated connector pair is expected to be less than 0.20 dB for single-mode (e.g., -0.20 dB). Let’s examine one scenario where a loss is not negative (e.g., +0.15 dB).
The typical process for validating the loss of a connector, to verify if it is “reference grade” for example, is as follows:

데이터 센터 공간에서 테스트
테스트하는 데이터 센터의 기능 영역에 따라, 접하게 되는 애플리케이션, 배선, 연결성이 달라집니다. 데이터 센터의 기능 영역과 각각의 영역에서 필요한 테스트를 이해하는 것이 데이터 센터 테스트를 준비하는 데 도움이 됩니다.

ANSI/TIA 568.2-D 승인!
The latest TIA standard for balanced twisted-pair cable systems – TIA 568.2-D – was approved for publication during the TR-42.7 meeting on 2018년 6월 12일. It will replace TIA-568-C.2 and is expected to be published in the coming weeks.
For the past year (or more), we’ve been talking about many of the changes we will see in this standard, and now that it’s approved, we decided a recap is in order.Letter Swapping

TIA는 여러분처럼 MPTL 연결을 인식합니다
If you are familiar with deployments where a horizontal cable run terminated on one end to an RJ-45 plug connects directly into a device, then you are familiar with what is now referred to as a Modular Plug Terminated Link, or MPTL (even if it wasn’t always referred to in this way).

여름 읽기: 4주 연속 상위 4가지 주제
While many of our blog readers are well versed in designing, installing and testing cabling systems, some of you may be new to the industry and still trying to make sense of the various performance parameters, standards and testing requirements that today’s cabling systems must meet to support the latest applications, acquire a vendor’s system warranty and ensure a successful installation for your customers.

28 AWG 패치 코드 정보
Over the past few years, several manufacturers have released 28 AWG patch cords that offer a smaller diameter to help improve airflow around active equipment and ease cable management at high density patching areas due to reduced congestion and a smaller bend radius.

어플리케이션 제한에 맞춘 설계
When it comes to calculating loss budget, it’s important to know the loss limits for the given application as specified by industry standards. But if I really want to know how to design a system to these limits, you also need to know the loss of the specific vendors’ cables and connectivity you plan to deploy—and that can impact exactly which components you specify. This can make the task a bit tricky as not all cables and connectors are created equal.
Let’s take a look at a real-world example.

5주년 Anni-Versiv™ 축하!
To some, it may seem like just yesterday that Fluke Networks introduced the Versiv™ family of Cabling Certification Testers, especially for those who are still hanging on to their discontinued DTX CableAnalyzer™ (don’t forget that all service and calibration for DTX CableAnalyzers ends this June 30th).

버즈야 물러가라!
While labeling per the ANSI/TIA-606-B Administration Standards is considered best practice, let’s face it—labels don’t always happen or sometimes they’re simply not visible where you need them. Over time, cabling links may also have been reconfigured in the telecommunications room or the data center. And when you need to trace a cable or simply identify the other end among hundreds of copper links, a toner and probe can be your best friend.

보십시오, 손이 필요 없습니다!
Did you ever have one of those days where your hands feel like two foreign objects that aren’t connected to your body or your brain? Yesterday started off as one of those days for me. It went something (maybe not exactly) like this.
The first mistake was my decision to carry too much stuff out to my truck while simultaneously balancing my coffee. It didn’t go very well. Not only was I now five minutes late from running back in to change my shirt, but now I had a cleaning charge to worry about.
