Network LAN or Ethernet cables connect devices such as modems, routers, computers, servers, and switches to the web. These cables are often taken for granted, with organizations randomly picking a cable and expecting a seamless connection. However, the network cannot function properly without the correct connection of these devices. This is why it’s important to choose the right Ethernet cable, especially when considering Cat5 vs. Cat6 Ethernet cables.
While both cables can connect devices to the internet, Cat5 supports speeds up to 100 Mbps and bandwidth up to 100 MHz. Cat6, on the other hand, offers faster speeds of up to 10 Gbps and bandwidth up to 250 MHz, making it ideal for high-performance networks. Choosing between them depends on your network’s speed and bandwidth requirements, with Cat6 being the better option for future-proofing your infrastructure.
When we discuss Ethernet cables, the two varieties that commonly come into the picture are Cat5 and Cat6, plus their common sub-varieties, Cat5e and Cat6a. Both the cable categories are good in their ways, helping different organizations to set up a strong connection. The only problem is finding out which cable is the right option for a particular organization.
The decision is very difficult because it’s about networking on which the operations of the entire company depend. To make your choice, we will discuss the differences between Cat5 and Cat6 cables. We will also give a brief of their sub-varieties.
About Cat5 Ethernet cables
Introduced in 1995, the Cat5 is the fifth generation of unshielded, twisted-pair Ethernet cable technology, which is also known as Unshielded Twisted Pair or UTP. Since its introduction, it has been the most popular twisted-pair cable.
This Ethernet cable contains four pairs of twisted copper wire that end with an RJ-45 connector, which plugs into a standard Ethernet jack.
The Cat5 Ethernet cables ensure high-speed internet with the ability to transfer data at 100 Mbps and 100 MHz bandwidth. In shorter distances, the cables run up to 2.5 GBASE-T.
Talking about Cat5’s sub-variety, the Cat5e offers Gigabit Ethernet speeds up to 1000 Mbps, and a bandwidth of 350 MHz Introduced in 2001, the Cat5e is compatible with standard Cat5 cables. Here, “e” stands for enhanced.
Physically, both the standard Cat5 and sub-variety Cat5e Ethernet cables look identical. The only difference is the Cat5e cables contain four pairs of copper wires instead of two. But, they are different in speed. The Cat5e cables are 10 times faster than Cat5 cables. A significant difference is experienced between standard and sub-variety cables in IT companies or companies dealing with a large amount of information.
The Cat5e cables are more rigorously tested than Cat5 to eliminate crosstalk or signal interference and are twisted more tightly.
Why should you use Cat5 Ethernet cables?
- Offer high-transfer speeds at a low cost
- Ability to transfer up to four signals in one-time
- Support Gigabit Ethernet
- Preferred for applications like networking, telephone wiring, etc.
- Come in both stranded form for flexibility and solid conductor form
- Easy installation without using any special tools
Why shouldn’t you use Cat5 Ethernet cables?
- Limitations in data transfer, only up to 100 Mbps of transfer speed
- Susceptible to signal noise from wireless devices, further reducing data transfer speeds
- Not recommended for network installations
About Cat6 Ethernet cables
Like Cat5e, the Cat6 Ethernet cables have four twisted pairs of copper wire with 250 MHz of bandwidth that support data transfer speeds of up to 10 Gbps (10GBASE-T). The distance is approximately 180 feet. The best thing about Cat6 Ethernet cables is that they are compatible with Cat5/5e and Cat3 cables.
The Cat6 Ethernet cables are also used for 328 feet but the maximum data transfer speed drops to approximately 1 Gbps. As the global standard for Ethernet cables, the Cat6 Ethernet cables are perfect for applications with substantial data transfer needs, including Internet of Things (IoT) setups.
Regarding Cat6a Ethernet cables, they have thicker, heavier construction than Cat6 cables. Here, “a” means augmented. The individual pairs of the wire have metal shielding to reduce interference further. They support 10 Gbps internet up to 328 feet at a maximum bandwidth of 500 MHz, which is double the bandwidth of Cat6. Most importantly, the Cat6a cables are compatible with Cat6 and Cat6e cables because of their shared RJ-45 jack.

Cat6a cables are used for applications outside data and telephony, such as automation and physical security systems like access control and CCTV. Also, these cables are preferred in networks with heavy data use but don’t need expensive fiber optic cables.
Why should you use Cat6 Ethernet cables?
- Have stricter performance specifications
- Speed of data transfer is significantly high at greater distances
- More tightly twisted than Cat5 cables
- Cable conductors and cable sheath are thicker
- Interior and exterior signal/ EMI interference is reduced to a greater extent
Why shouldn’t you use Cat6 Ethernet cables?
- While Cat6 Ethernet cables offer higher speeds and better performance than Cat5, they come with certain drawbacks. Cat6 cables are more expensive than Cat5, making them an unnecessary investment for many organizations that don’t require top speeds or high bandwidth today. For standard business operations, Cat5 Ethernet cables may already meet their needs efficiently.
- Cat6 cables also tend to offer more than what most organizations need currently. If your network doesn’t require speeds over 100 Mbps or advanced bandwidth, Cat5 cables are usually sufficient.
- Additionally, Cat6 cables are thicker and less flexible, making them difficult to use in limited spaces. If you have a cramped setup or need to run cables through tight spaces, Cat5 is often the better, more practical choice.
- In comparing Cat5 vs. Cat6 Ethernet, Cat5 supports speeds up to 100 Mbps with a bandwidth of 100 MHz, suitable for most everyday uses. Cat6 can handle speeds up to 10 Gbps with a bandwidth of 250 MHz, which is ideal for more demanding, high-performance networks. The decision between the two should be based on your current network needs, budget, and installation space.
Cat5 vs. Cat6 Ethernet Cables: What’s Best for You?
Additional thickness/stiffness makes the cable less flexible and harder to work with
Cat6a are around 40-50% thicker and heavier than Cat6
As already stated, both Cat5 and Cat6 Ethernet cables are perfect in their ways. So, you should determine the needs of your organization before deciding on the best option. For example, if you have money and want higher data transfer, you should choose Cat6 Ethernet cables. On the other hand, if 100 Mbps speed transfer is enough, you should opt for Cat5 Ethernet cables. They will fulfill your requirements at a low cost.
Try to determine the requirements based on different factors such as industry, operations, flexibility, and others. To know more about Ethernet cables
