You may have heard that propagation delay and delay skew parameters are important for IPTV, surveillance and video conferencing, and many vendors may tout delay skew performance for these video applications.

But do you know why these parameters are important for video applications? As part of our Cable Testing 101 series, we thought you might want to know more.

울펜슈타인 3D가 한창 유행할 때, 우리는 BICSI 컨퍼런스에서 잡음을 유도해서 Cat 5 링크 실패를 일으키는 전시를 선보였습니다. 우리는 형광등 안정기, 큰 전기 모터와 심지어 시동 걸린 자동차 엔진의 코일에 케이블을 배치하는 등의 모든 종류의 금기를 시도했지만, 링크는 실제로 오류 없는 100BASE-TX 성능을 제공했습니다. 그 시점에서, 대부분의 설치에 대해 스크린된 케이블이 많은 도움이 될 것처럼 보이지 않았습니다.

On January 23, we announced the DSX-8000 CableAnalyzer™, the first true Category 8 tester.  You may be wondering what is required for a “true” Category 8 certification tester and why we launched it now.

A wire map test may seem like the most basic test for copper network cabling and therefore one of the least important, but 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.

So you came across some Category 6 cable available online for practically half what you've been paying for that brand name. It claims TIA-568-C compliance, includes the UL listing mark and even has a ETL verification legend printed right on the cable. Before you get too excited, you might want to make sure that cable isn't made with copper clad aluminum (CCA).

All over the news and social media, 2016 has gotten a pretty bum rap.

With everything from shootings, terrorist attacks and the weirdest presidential election in history, to exploding cell phones, scary clown threats and numerous celebrity deaths, 2016 has been denoted as the worst year ever.

The only way to get correct values when performing Tier 2 testing of duplex fiber links with an OTDR is via bidirectional testing that averages the measurements taken from both ends of the link.

Bidirectional testing used to involve testing the fiber from one end, walking the OTDR to the other end to test again and then averaging the two values to get the results—and it had to be done for each link.

'Twas the night before Christmas when all through the LAN, 
the channels were tested except for the SAN.
MPOs easy with MultiFiber™ Pro,
gave me hope I'd be done before fallen snow.
With SmartLoop letting me to test from one end,
I knew that I'd soon start my weekend.
