101 Serie: Stranded vs. Solid Patch Cords

You’ve likely heard copper patch cords referred to as being constructed of either “stranded” or “solid” cable, but do you know the difference and which to choose when? 

Just like the name implies, stranded four-pair cables are cables where each of the eight conductors of the four-pair cable are constructed of multiple “strands” of wires wrapped around each other, while solid cables are constructed with just one solid copper wire per conductor.

Short-Reach Singlemode Puts Reflectance on the Radar

Most of us are well aware that insertion loss budgets have gotten tighter as we have moved from 10 to 40/100 Gig for multimode fiber applications. One would think that we can’t say the same for singlemode applications that have historically meant larger loss budgets – 6,3 dB for 100 Gig over singlemode (100GBASE-LR4) versus just 1,9 dB for 100 Gig over multimode (100GBASE-SR4). But that’s no longer the case with new short-reach singlemode applications.

101 Series Ethernet: Zurück zu den Basics

It’s been more than 40 years since Bob Metcalfe published this simple diagram explaining his invention for interconnecting computers and printers at the Xerox Palo Alto Research Center in California. His patented multipoint data connection system with collision detection later became known as Ethernet.

Know the Punch Line

Installers have been punching down copper twisted-pair cable for decades and still do so for terminating cables to IDC towers on jacks, patch panels and connecting blocks. While the practice hasn’t changed, punchdown tools have come a long way, and you now have some options at your fingertips. So how do you choose? Werfen wir einen genaueren Blick darauf.

Not Exactly in the Limelight – Yet.

Es ist schon eine Weile her, dass wir über OM5-Multimode-Faserkabel gesprochen haben und darüber, dass dieses Kabel trotz der hellgrünen Farbe und der Hinzufügung zum ANSI/TIA-568.3-D-Standard im Jahr 2016 bisher noch nicht mehr Aufmerksamkeit erlangt hat – was sich aber wohl in Kürze ändern wird.

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.

Channel, Permanent Link, Patch Cords, MPTL, E2E... Oh je!

Jetzt, da die MTPL-Konfiguration (Modular Plug Terminated Link) zum neuesten ANSI-TIA 568.2-D-Standard hinzugefügt wurde, und auch noch E2E-Konfigurationen in ISO/IEC-Standards Aufmerksamkeit erwecken (und wahrscheinlich auch bald in TIA), können die Auswahlmöglichkeiten überwältigend erscheinen, und Sie fragen sich vielleicht, was Sie testen sollen und wann. Werfen wir einen Blick darauf.
