Comparing Cat6, Cat6a and Cat6e: Which is Best for Your Network?

The world of digital communication continues to evolve. And with that evolution comes a greater need for faster, better, and more reliable networking cables. Cat 6, Cat6a and Cat6e are three popular options that all offer something different in terms of bandwidth, transmission speed and maximum length. So which is the best for your needs?

In this article, we'll compare the benefits of each type of cable and explain why choosing one over the other can help make the most of your network's performance. We'll also cover staying within budget requirements, as well as which type of network cable works best for different environments. Read on to learn more about Cat 6, Cat6a, and Cat6e.

What is Cat 6 Cable?

Cat6 cable, or Category 6 cable, is an Ethernet cable standard developed by the Electronic Industry Association (EIA) in 2002. It's commonly used in cable systems intended for 10/100/1000Base-T networks, where it supports data transfer speeds up to 10 Gbps.

Cat6 is typically made from polyethylene and copper, and contains four-pair twisted pair wiring. It's designed for use in Ethernet, Fiber Optic, and Power over Ethernet applications. The outer insulation is designed for maximum resistance against EMI and RFI interference.

What is Cat6a Cable?

Cat6a cable, or Category 6a cable, is an enhanced version of Cat6 cables. It was introduced in 2010, and is designed for use in 10/100/1000BASE-TX networks. Like its predecessor, Cat6a supports up to 10Gbps speeds, but with improved alien crosstalk (AXT) and improved bandwidth.

It is also made from polyethylene and copper wiring, but utilizes 8-pair twisted pair wiring. This provides better shielding, which minimises noise and crosstalk. It also comes with an outer insulation that is thicker than Cat6 cables and provides stronger protection against EMI and RFI interference.

What is Cat6e Cable?

Cat6e cable, or Category 6e cable, is the latest iteration of Ethernet cables. It was introduced in 2016, and like its predecessors, it is designed for use in 10/100/1000BASE-T networks. It offers faster data transfer speeds of up to 25Gbps and improved AXT, making it ideal for high-traffic networks.

Like Cat6 and Cat6a, Cat6e is made from polyethylene and copper wiring, but uses four-pair twisted pair wiring. It also comes with an outer insulation designed for maximum protection against EMI and RFI interference.

Pros and Cons of the Three Cables

The following table outlines the benefits and drawbacks of the three cables:

Cable Type	Pros	Cons
Cat 6	Supports up to 10 Gbps Relatively inexpensive	Susceptible to alien crosstalk Higher levels of noise
Cat 6a	Enhanced alien crosstalk Lower levels of noise	More expensive than Cat 6
Cat 6e	Supports up to 25 Gbps Enhanced alien crosstalk and noise prevention	More expensive than Cat 6a

Which Cable Should You Choose?

Choosing the right cable will depend on several factors, including your budget and the environment in which your network operates. Here’s a quick summary of which type of cable works best in different scenarios:

Cat6 is a good option for basic 10/100/1000Mbps networks on a tight budget.

Cat6a is a good choice for 10/100/1000Mbps networks in places where there is heavy electrical interference.

Cat6e is the only option for networks requiring higher speeds, such as 10/100/1000/10,000/25,000 Mbps.

In short, it’s important to choose the right cable for your environment and budget. Doing so will ensure that your network performs optimally and that you get the most out of your investment.
