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 2018 年 6 月 12 日.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.

TIA 568.2-D Approved

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).

While many of our blog readers are well versed in designing, installing and testing cabling systems, some of you may be new to the industry and still trying to make sense of the various performance parameters, standards and testing requirements that today’s cabling systems must meet to support the latest applications, acquire a vendor’s system warranty and ensure a successful installation for your customers.

Over the past few years, several manufacturers have released 28 AWG patch cords that offer a smaller diameter to help improve airflow around active equipment and ease cable management at high density patching areas due to reduced congestion and a smaller bend radius.

Despite causing a bit of controversy in the industry since they were not originally recognized within ANSI/TIA cabling standards that require twisted-pair structured cabling to consist of 22 AWG to 26 AWG cables, these skinny patch cords continued to grow in popularity.

When it comes to calculating loss budget, it’s important to know the loss limits for the given application as specified by industry standards.But if I really want to know how to design a system to these limits, you also need to know the loss of the specific vendors’ cables and connectivity you plan to deploy—and that can impact exactly which components you specify.This can make the task a bit tricky as not all cables and connectors are created equal.

Let’s take a look at a real-world example.

To some, it may seem like just yesterday that Fluke Networks introduced the Versiv™ family of Cabling Certification Testers, especially for those who are still hanging on to their discontinued DTX CableAnalyzer™ (don’t forget that all service and calibration for DTX CableAnalyzers ends this June 30th).

ANSI/TIA-606-B 管理規格(ANSI/TIA-606-B Administration Standards)に基づいたラベル付けが推奨されていますが、現実には、ラベル付けされていなかったり、必要な場所にラベルが表示されていなかったりすることがあります。また長い年月の間に、通信室やデータ・センターのケーブル配線リンクが再構成されることもあります。ケーブルの配線経路を追ったり(トレース)、数百本もあるメタル線の中から特定のケーブルの片端を見つけたりする必要がある場合は、トーナーとプローブが必要になります。

Did you ever have one of those days where your hands feel like two foreign objects that aren’t connected to your body or your brain?Yesterday started off as one of those days for me.It went something (maybe not exactly) like this.

The first mistake was my decision to carry too much stuff out to my truck while simultaneously balancing my coffee.It didn’t go very well.Not only was I now five minutes late from running back in to change my shirt, but now I had a cleaning charge to worry about.
