케이블링 산업 현황

다음주 BICSI 가을 컨퍼런스 및 전시회에서 많은 것을 배울 수 있습니다 (CEC 포함)

At the upcoming BICSI Fall Conference & Exhibition on September 9 – 13 at the Henry B. Gonzáles Convention Center, San Antonio, TX, there are plenty of opportunities to learn about the latest technologies, and Fluke Networks is excited to bring you the latest on testing everything from advanced four-pair PoE to passive optical networks (PONs).

와이어 맵 테스트: 색에 관한 것이 전부는 아닙니다

Virtually every Ethernet cable tester can perform a wire map test - likely the most basic test for copper network cabling. Despite being a basic test, it is actually one of the most critical. And while the pair colors of blue, orange, green and brown might help you pass wire map testing, the test itself really doesn’t care about color at all.

Let’s take a closer look.

200 및 400Giga의 길은 이미 포장되고 (통행 중입니다).

The increasing demand for higher bandwidth to support Big Data has driven the need for ever-increasing Ethernet speeds, starting with 10 Gig in 2004 to the introduction in 2010 of 40 Gig with 4 fibers transmitting and 4 fibers receiving at 10 Gbps (40GBASE-SR4) and 100 Gig with 10 fibers transmitting and 10 fibers receiving at 10 Gbps (100GBASE-SR10).

Troubleshooting Installed Cable with DSX-5000 CableAnalyzer

It felt like a Monday morning when the call, actually an e-mail, came in. “I think my DSX is broken!” As you know, they are really tough machines and, when it looks like the Fluke is wrong, usually it isn’t.

“What makes you think it is broken?” I asked, “How does this failure manifest itself?”

“The tester is failing links that used to pass.”

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).
