Mit der Einführung von Glasfaserbestandteilen mit geringer Dämpfung, wie LC/MPO Kassetten, nehmen Dämpfungsverlustbudgets (Testgrenzwerte) zunehmend ab. Infolgedessen finden Installateure heraus, dass vorige Methoden und Annahmen über Glasfaserprüfung nicht länger zutreffen.

Während die Telecommunications Industry Association (TIA) noch 0,75 dB pro Verbindungsstück zulässt, liegen fabrikgefertigte Verbindungsstücke näher an 0,2 dB. So stehen Installateure bei Prüfungen zu den TIA-Bestimmungen einigen Messabweichungen gegenüber. Das heißt, dass ihre Prüfverfahren angemessen aber nicht perfekt sein müssen.

Während Firmen versuchen, der steigenden Nachfrage im IP-Verkehr nachzukommen, um eine wachsende Reihe Geschäftsanwendungen zu unterstützen, konzipieren viele Unternehmen ihre Rechenzentren mit Faseroptik-Netzwerken, die 10G oder 40G Ethernet-Verbindungen zwischen Servern, Switches und Speicherbereich-Netzwerken sowie 100G Ethernet für Kernschaltungen und zum Routen von Backbone-Verbindungen unterstützen.

What do Albert Einstein and Michael Jordan have in common?  No, they’re not both LinkWare users… They focused on continuously learning and pushing the envelope even though they were already far ahead of everybody else. Just like our engineers who worked tirelessly to rebuild LinkWare from the ground up and make the best even better. Improvements include:

By now you will have heard about the new OptiFiber Pro OTDR  and that’s a relief for me because I’ve been biting my tongue for a while!  Now that its been announced, let me share my impressions and an overview of what makes the product unique.  I will also include some links to more detailed information.  Take this from a guy that has spent five of the last seven years playing with OTDRs… I’ve used them all.  And this one is going to change everything!

The end of March marks one year since calibration and service was available for the DSP 4300, and an end of an era for technicians certifying cabling with the Series.  It was a long love affair. The DSP 100 was the first of the Series. It was introduced in 1995. That year the DVD was selected as the home video format, a gallon of gasoline cost $1,09, and we all had to undure the infamous OJ Simpson trial.

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.

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.

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.

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.
