difference between cat5 and cat6

If you’re building up your IT infrastructure, you’ll quickly come across a choice between two Ethernet cable options – Cat5 and Cat6. While they may look the same, they have some crucial differences. Here’s a breakdown of what you need to know.


Cat5 is the older and more straightforward of the two Ethernet cable types. It has been used in networking for decades and is still widely used today. Cat5e (enhanced) is a more modern version that has improved upon the original Cat5.

Cat5 cables are affordable and come in various lengths to suit your needs. They are perfect for small businesses and home networks where speed requirements are not particularly high. They support Gigabit Ethernet, which is a significant improvement over older standards, so they can handle speeds of up to 1 gigabit per second (Gbps).

Disadvantages of Cat5

The biggest downside to Cat5 is that they are not as fast as some of the more modern Ethernet cables, like Cat6. They also have lower resistance to crosstalk, which refers to interference from other cables. When cables face high interference levels, the data transmission rates can suffer. As a result, Cat5 cables may not be able to support some high-speed applications.

Cat6 cables are newer and faster than Cat5. They have been designed to handle more data, and they are more resilient to interference. Cat6 cables can support speeds of up to 10 Gbps over short distances.

While Cat6 is generally newer and faster, it is a bit more expensive than Cat5. Its cable jacket is also thicker than Cat5 cables, and the higher strands of wire inside the cable make it stiffer, harder to bend, and trickier to work with.

Advantages of Cat6

The advantages of Cat6 cables make them worth the additional cost for many business owners. They have a much higher capability to handle higher network speeds and provide you with reliable connectivity. They are also more resistant to interference, offering a better signal-to-noise ratio.

In summary, Cat5 cables are suitable for simple setups that don’t require high network speeds. They are known for their affordability and versatility. Cat6 cables are faster and more efficient, but more expensive. They are ideal for businesses and enterprise networks that require reliable and lightning-fast internet speeds.
