Considerations for Choosing Stranded vs. Solid Cable

You’re probably aware that both shielded and unshielded twisted-pair copper cable comes in either stranded or solid wire versions. There are plenty of considerations when it comes to choosing one or the other, including standards, environment, application, and cost. Let’s take a look at the differences and considerations, so you can decide which cable type is right for your specific installation.

History of the RJ45: A Case of Mistaken Identity

Our industry commonly uses the term “RJ45” to refer to the modular 8-position, 8-contact (8P8C) interface deployed for Ethernet over copper twisted-pair network cabling despite it pretty much being a case of mistaken identity.

But since the RJ45 name has stuck, we thought maybe we’d take a closer look at the history of this nomenclature and why to this day, it remains the de facto interface for twisted-pair Ethernet applications.

Cable Testing 101: What’s My Loss Budget?

While you might hear your CFO grumbling about staying under budget from a dollar perspective, staying under your loss budget from a fiber perspective has a much bigger impact on your network performance – which ultimately impacts your bottom line by avoiding downtime.

But how exactly is your loss budget defined and how do you ensure you don’t exceed it?

This Decade’s Top 5 Tech Flicks for Your Holiday Downtime

As we head into the holidays and a new decade, you may find that you’ve finally got some time to wind down at home as you use up the remainder of this year’s vacation days. And even if you’re stuck in the office keeping the network up and running, it’s a quiet time of year that might warrant a long lunch to watch Netflix on your laptop.

Troubleshooting Fiber on the Cheap

If you troubleshoot fiber on a regular basis, you probably have an array of tools to help you do the job, including an Optical Time Domain Reflectometer.  But we often get questions from customers who don’t troubleshoot fiber enough to justify such an expensive tool.

The Poet’s Guide to the Physics of Twisted Pair Cabling

I once took a class where the professor would explain concepts in two ways.  First, he would dive into the mathematics behind the idea, filling the whiteboard with equations and showing how they all related to one another.  He tagged this “for the engineers”.  Then, he would explain the concept again, but this time, with no math at all.  This he said, was “for the poets”.

6912-Fiber Cable: Now That’s Testing!

While most enterprise data centers see fiber counts ranging from 12 to 144, the fibers counts found in cloud and colocation data centers are much higher – typically anywhere from 864 to 1728.
