What are the different types of Ethernet cables?

Ethernet cables are essential for connecting devices to a network. There are different categories of ethernet cables, each with its specifications and capabilities. Let’s take a closer look at the major categories of ethernet cables.

Cat 5

Cat 5 is an older form of ethernet cable that uses pure copper conductors. This category was replaced by Cat 5e in 2001. Although Cat 5 technically supports Gigabit transfer speeds (1000 Mbps), it does not do so very well. Consequently, it is rarely used now.

Cat 5e

Cat 5e is an upgraded version of Cat 5 that has the same bandwidth (100 MHz) and construction. However, it has upgraded specifications that remove cross-talk (interference), making it a more reliable version of Cat 5. This enhanced performance means it can support Gigabit speeds (1000 Mbps) more easily.


Cat 6

Cat 6 is an improved standard of ethernet cable that supports performance of up to 250 MHz and speeds of up to 10 Gigabits per second up to 55 meters range. It also has improved construction standards that reduce cross-talk even further than Cat 5e.

Cat 6a

Cat 6a is almost identical to Cat 6, but it supports twice the performance (500 MHz) and has further improvements over Cat 6 in reducing interference.

Cat 6e

Cat 6e is a newer form of Cat 6, but it is not officially recognized as an ISO standard. Despite this, some cables are still labeled as Cat 6e commercially.


It’s important to note that Category 6 and 6e cables are fully backward compatible with the 5/5e standards and ports. Therefore, any cable will work with any device that has an ethernet port.

Cat 7 and Cat 8

Cat 7 and Cat 8 cables are also available, but they are not widely used at the moment.


What are the steps to installing a router compatible with Cat6?

  • To install a Cat6-compatible router, remove the old router and cables.
  • Connect the new router to your modem with an Ethernet cable.
  • Plug cables in the router and turn it on.
