AV over Twisted-Pair: What Do I Need to Test For?



Not Exactly in the Limelight – Yet.

It’s been a while since we’ve talked about OM5 multimode fiber, and despite its lime green color and being added to the ANSI/TIA-568.3-D standard in 2016, it hasn’t exactly been in the limelight – but it looks like that won’t always be the case.


Cabling Chronicles’ 4th of July Reflections

The 4th of July is always a time to reflect on our history, where we come from and the dedication of our founding fathers. But it’s also a time to look ahead, learn from past mistakes and progress towards a better future.



With the addition of the modular plug terminated link (MPTL) configuration to the latest ANSI-TIA 568.2-D standard, and now end-to-end (E2E) configurations getting some attention in ISO/IEC standards (and likely soon TIA as well), you might be overwhelmed with the choices and be wondering what you’re supposed to test and when. Let’s take a look.

Part 3 of a three-part series

In this day and age, with everyone preparing for the future of 5G, the internet of things, and industrial automation, if you’re a contractor or technician you better know and understand loss budgets!



While the fact that a fiber link’s transmit signal (Tx) must match the corresponding receiver (Rx) at the other end makes perfect sense, ensuring proper polarity to ensure that this correspondence is maintained continues to cause plenty of confusion – especially when it comes to multi-fiber MPO connectivity where 12 fibers located in Position 1 through 12 at one end must each arrive at their corresponding position at the other end.



If you’ve turned on the news in the past couple of months, or if you live anywhere in the southern or central U.S., you’re well aware that natural disasters are at an all-time high – from recent tornadoes that have stretched from Texas north to Minnesota and east to Pennsylvania, to the swelling Missouri, Mississippi, Arkansas and Ohio Rivers and their tributaries causing flooding in nearly two-thirds of the country.


新しい Wi-Fi 6 で必要なテスト

Earlier this year, the IEEE released its 802.11ax Enhancements for High Efficiency Wireless (HEW) LAN standard, known commonly as Wi-Fi 6. This new advanced Wi-Fi application is positioned to theoretically deliver close to 10 Gig transmission through the use of eight spacial streams that each transmit at 1.2 Gb/s compared to Wi-Fi 5 (802.11ac) at just 866 Mb/s per special stream. It also has the ability to operate in both the 2.4 GHz and 5 GHz bands.


新しい高密度光ファイバー・コネクター登場に伴う Tier 1 テストの課題

データ・センターの高密度化ニーズに対応するために、最近 2 つの新しい光ファイバー・コネクターが発売されました。ただし、これらのコネクターはまだ新しいため、これらに対応したインターフェースを持つテスト機器がまだ存在しません。これは、Tier 1 試験を実施するうえで問題となるため、推奨される従来の 1 ジャンパー基準法から切り替える必要があります。では、これらのコネクター・タイプとそのテスト方法について詳しく見ていきましょう。
