CMR or CMP Rated Network Cable?

These two acronyms are confusing as the “C” and the “M” do not indicate separate words, but are an abbreviation for “CoMmunication”:

  • CMR = Communications Riser
  • CMP = Communications Plenum

Booted vs. Non-Booted Network Cables

A "booted" cable is a cable that has a molded "plastic" boot that fits on the cable end of the connector and a portion of the cable itself. Sometimes a booted cable is also referred to as a "strain-relief" cable, which is exactly the purpose of the boot…

There are two main types of boots that you will encounter, a separate boot that you can purchase to put on a cable that your are making on your own, or when you buy a manufactured cable that has its own injection molded boot.

Cat5e vs. Cat6 vs. Cat6a
There are a lot of articles on the Internet about the differences between Cat5e and Cat6 cables and their standards, there are many differences of opinion about where and when you have to use the two cable types. One common misconception is that Cat5e patch cables are not able to run at Gigabit speeds, and Cat6 is required. This is not the case, and most modern Cat5e cables are perfectly capable of running at Gigabit speeds, you will see printed on the outer jacket of the cable that the cable is certified for Gigabit networking.

What is Crosstalk?
Crosstalk is a complicated subject to grasp, especially where the "Near" and "Far" ends are. In reality both end of the cable are both! They are only reference points to demonstrate where the signal is originating from for the purpose of the test… The first diagram in this article shows exactly what happens, and how the "concept" of what is the Near and Far ends depending on which end the signal originates from.
