"Category 6a is particularly resistant to interference from older Ethernet signaling..."

Question

I'm going through "Unix and Linux System Administration Handbook", 5th edition. In chapter 14, "Physical networking" in the section on UTP cabling, it says:

Category 6a is the cable of choice for new installations because it is particularly resistant to interference from older Ethernet signaling standards (e.g. 10BASE-T), a problem that has plagued some Category 5/5e installations.

What does this mean? That a cable with 10BASE-T running on it will project heavy interference on nearby Cat5 cables, but Cat6-es will be just fine? Is there any reading available on the Internet on this issue? I simply want to make sure I got it right (English is not my first language). Thanks.

Answer 1

It means that if you are in an environment with heavy interference cat6e will work better then earlier standards - but not that they will work fine.

Google CAT6e vs CAT5E - for example this link describes the differences - https://www.diffen.com/difference/Cat5e_vs_Cat6
