ケーブリング・クロニクル

Would you fight this speeding ticket? The 10% rule explained.

Ironically my desire to speed in traffic evaporated when I bought a real sports car.  But this story is not about me and my desire to push the limits.  It’s about you.

Cloudy days ahead!

クラウドがどこでも話題になっています。 話題の多くは、データや電子デバイスの操作方法がどのように変わるかについてです。 しかし、ケーブリング業界はクラウドがどのようなビジネス・チャンスになるかに注目しています。

Re-upped!

I received my new RCDD certificate, good through the end of 2014, in the mail last week. My reaction was more pensive than the elation I experienced after first passing the exam in 2003.

Why a Cat 6A Patch Cord Adapter has that funny little “A” next to the 6

If you’ve seen a set of Category 6A  Patch Cord Test Adapters, you may have wondered why the “A” is subscripted.  It has to do with the standards that the adapters support. The little “A” denotes that the adapter meets the ISO/IEC specifications for a patch cord test.

The worlds most trusted cable tester reaches an imporant milestone

When I was a technician we worried about, bad cable, poorly performing jacks, and doubted our testers. The threat of ongoing callbacks and the risk of large installation re-dos keep contractors up at night. Those that have passed the test of time don’t leave much to chance.  But the contractors I know do make decisions based on trust. And trust is earned over time through a series of trials, tests and demonstration of performance.

VoIP for the masses…the end of “voice grade cabling”

When I was a cable installer, we often built redundant networks for voice and data communications.  The data cabling was terminated on patch panels, and the voice grade cabling was terminated on wiring blocks. There are thousands of installations done this way.  And there were lots of reasons for it, including cost.  But I think the major reason we kept installing separate “voice grade cabling”  was that , deep down, the key influencers of cabling installation design didn’t believe that the end of voice circuits  would ever happen.

Fluke Network's fiber optic technologist Seymour Goldstein just returned from Melbourn Australia where he attended IEC SC86C/WG1, and ISO/IEC JTC 1 SC25/WG3  meetings.  I caught up with him this week and got a download from his trip.

Bridge Taps Killing DSL Performance? New TS100 PRO Cable Fault Finder Detects Multiple Bridge Taps on DSL Cable Lines

Today we announced a new product, the TS100® PRO Cable Fault Finder, the first field technician tool that can detect multiple bridge taps on DSL cable lines and can detect taps up to 3,200 feet. Bridge taps are extra lengths of cable that are a killer to DSL performance and can be costly to detect. They have become increasingly present on a significant number of cable lines, due in part to cost pressures and an increased demand for broadband.

A visit from visionaries Koeman, Thwing, and Martins.

The other day I heard a familiar, yet unexpected voice coming from the Fluke Networks Lab. In a moment I recognized the voice of Henri Koeman, the retired long time Fluke Networks employee and veteran of the cabling standards commitees.
