케이블링 산업 현황
Type 3 and Type 4 are Here!
Last week the IEEE 802.3bt standard for Type 3 and Type 4 PoE was finally ratified! While we’ve been talking about these higher levels of PoE for quite some time, now that they are finally an approved standard, we thought it was a good time to clear the air on PoE types, classes, and certification, as well as provide a refresher on our specialty—testing.

혼합된 생각
케이블링 인프라에 관한 한 모든 미디어와 애플리케이션이 항상 같지 않습니다. 따라서 모든 링크 각각에 대해 미디어 유형과 애플리케이션 관점 모두에서 무엇을 테스트 하는지 아는 것이 중요합니다.

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).

101 시리즈: 스플라이스를 하느냐 안하느냐
Fiber splicing is a method of connecting two fibers, whereby two fibers are precisely cleaved and then aligned and fused using a fusion splicing machine. The fusion of two fibers is achieved by an electric arc that essentially welds the fibers together. A mass fusion splicer welds 12-fiber together at once and is performed using 12-fiber ribbon cable.

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.”
