Wolfenstein 3D のゲームが大人気だった頃、当社は BICSI カンファレンスで Cat 5 リンクにノイズを引き起こすことで障害を発生させる試みを行いました。私たちは、蛍光灯安定器、大きな電動機、エンジンのかかった車の点火コイルの近くにケーブルを配置するなど、さまざまなやってはいけないことを試しましたが、それでもリンクはエラーフリー同然の 100BASE-TX パフォーマンスを提供しました。当時、ほとんどのケーブル敷設環境では、遮蔽付きのケーブルの利点はそれほどないように思われていました。

The 2017 BICSI Winter Conference wrapped up last week in Tampa where thousands of ICT professional from around the world had a chance to gain valuable industry knowledge and check out the latest products from nearly 180 vendors in the exhibit hall – including our new DSX-8000 CableAnalyzer.

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.

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.

テストで来年最も注目される動向を予測する時期が今年もやってきました。

言うまでもなく、モノのインターネット(IoT)はこれからもすべてのネットワーク配線において最も重要な要因になります。LAN のメタル線ツイストペア・ネットワーク・ケーブルには今まで以上に多くのデバイスが接続されます。また、より多くのデータにアクセスし、送信、保存する必要性に迫られる企業が増えるなか、データセンターの高速光ファイバー・リンクに対する需要は拡大していきます。
