What’s Better for You: Cat5 or Cat6 Ethernet Cables?

Find the differences between Cat5 or Cat6 Ethernet Cables and choose the best one for you. You might have yet to give much thought to the wire that connects your devices to the Internet. You might still need to remember them. There are some important differences between Cat5 or Cat6 Ethernet Cables that you should look into before you buy one.

Cat” stands for “category,” and “cat” connections are used to link computer network devices like modems, routers, computers, servers, and switches. You might also hear them called Network, LAN, or Ethernet connections. In this piece, we’ll compare Cat5 or Cat6 Ethernet Cables and their most popular subtypes, Cat5 or Cat6 Ethernet Cables. We’ll also discuss what makes each cable different and which Cat connection suits your needs.

What is a Cat5 or Cat6 Ethernet Cables?

Cat5 lines have four pairs of copper wires that are linked together. They end with an RJ-45 plug that fits into a normal Ethernet jack. It is the fifth version of unshielded, twisted-pair (also called Unshielded Twisted Pair, or UTP) Cat5 or Cat6 Ethernet Cables technology.

Since its release in 1995, it has been the most popular type of twisted-pair connection. Shielded Twisted Pair, or STP, is another type of Cat5 that protects against EMI and signal interference.

The Cat5 Ethernet connection opened the way for high-speed Internet. It can send data at 100 Mbps and 100 MHz bandwidth (100BASE-T or Fast Ethernet) but run up to 2.5GBASE-T at shorter distances.

Cat5 lines can carry data, phone, and video messages and should be no longer than 100 meters (328 feet). If your PC is connected to your network, use a normal Cat5 line to connect to the Internet.

What is an Ethernet Cat5e Cable?

Cat5e (the “e” stands for “enhanced”) is a better version of the Cat5 cable standard that came out in 2001. It supports Gigabit Ethernet speeds of up to 1000 Mbps, has a bandwidth of 350 MHz, and is compatible with regular Cat5 lines. Standard Cat5 connections can handle Gigabit speeds, but only up to 5GBASE-T lengths.

Cat5e wires are 10 times faster than regular Cat5 lines and meet the standards set by ANSI/TIA-568. Most likely, you won’t notice much of a difference in speed for home or small business network cables, but it makes a big difference for IT companies or companies that deal with a lot of information (think terabytes).

The Cat5e cable looks the same as the Cat5, but it has four pairs of copper lines instead of two. It will also say “5e” instead of “5” on the outside of the cable. To eliminate crosstalk or signal confusion, these cables are tested more thoroughly than normal Cat5 wires and twisted much more tightly.

What’s good about Cat5 Ethernet Cables?

Cat5 lines can send signals quickly and cheaply and up to four signals at once. Gigabit Ethernet can also work with Cat5 connections. These flexible wires can be used for many things, such as networking and phone wiring. They can be stranded, giving them more freedom for things like custom patch cables or solid, making them easier to place in the walls of a house or business and better protection than stranded versions.

Cat5 lines are also easy to set up and don’t need any special tools. You can easily change your Cat5 lines to Cat5 or Cat6 Ethernet Cables to increase your network speed and eliminate crosstalk. Cat5 wires were the best for a long time because they were easy to use, cheap, and common.

What are some problems with Cat5 Ethernet cables?

The biggest problem with Cat5 connections is that they can’t send as much data as other wires. They can only send data at speeds of up to 100 Mbps. This is fine for a home or small business, but it will only work for a small business that needs networking. Also, Gigabit Ethernet is being added to more home computers daily. If you ever want to set up a smart home or make sure your home network will work in the future, you shouldn’t use Cat5 cords.

Unshielded Cat5 connections can pick up signal noise from wireless devices, slowing down the speed at which data can be sent. Cat5e and Cat5 lines are only sometimes recommended for new network setups, but they can still get the job done for less money in many situations.

What's Better for You Cat5 or Cat6 Ethernet Cables

What is a Cat6 Ethernet Cable?

Cat6 Ethernet connections comprise four sets of copper wire that are linked together. They have a frequency of 250 MHz and can send data at up to 10 Gbps (10GBASE-T) for up to 180 feet.

Cat6 cables use the same RJ-45 plug that Cat5 cables and older Ethernet connections used. Cat6 cables can also be used with Cat5/5e and Cat3 lines.

At 328 feet away, the highest speed of data flow drops to about 1 Gbps. They meet the requirements for apps that need to move a lot of data, such as Internet of Things (IoT) setups like smart homes, school/enterprise networking setups, and data centers. Cat6 lines are now the standard for Ethernet connections everywhere in the world.

What is an Ethernet Cat6a Cable?

Cat6a lines (the “a” stands for “augmented”) are bigger and heavier than regular Cat6 wires. Each pair may also have metal protection to cut down on crosstalk even more. Cat6a lines can handle 10 Gbps Internet up to 328 feet at a maximum speed of 500MHz, which is twice as much as Cat6. There are strict rules about how to end these lines, and they must meet ANSI/TIA-568 standards. Due to their similar RJ-45 jack, Cat6a cables can be used with Cat6 and Cat6e lines.

Cat6a lines are great for more than just data and phone calls. They are great for automation and security systems like entry control and CCTV. They are often used in networks that send and receive much data but don’t need the more expensive fiber optic lines. These networks are popular in areas like healthcare and higher education.

What’s good about a Cat6 Ethernet cable?

Cat6 lines have tougher performance requirements than Cat5/5e cables and can send data faster over longer distances. They are wound tighter than Cat5 cables, and the wires inside and the outside of the line are thicker.

Together, these things limit signal/EMI interference from the inside and outside more than Cat5 lines. This is a great way to set up a network in an industrial setting where motors, engines, or wireless devices interact with the signal.

What are some problems with a Cat6 Ethernet cable?

Cat6 wires are usually 10–20% more expensive than Cat5e cables and are generally more than most homes need today. But that doesn’t mean they won’t be needed in 5–10 years when more houses are tied to the Internet of Things.

Cat6 lines are the best choice for networks that move masses of data or have a lot of signal noise. If you have the money and want to make sure your IT system will work in the future, you should go with Cat6.

Cat6 wires are thicker and have more padding, which may be a problem if room is tight. The cables are also less flexible and harder to work with because they are stiffer. Cat6a cables are bigger and heavier by about 40–50% and cost even more than Cat6 lines.


Q1. Is Cat5 or 6 better for Ethernet?

Cat6 is a good choice if you want faster Internet.

Q2. Why Cat6 is better than Cat5?

The performance standards for Cat6 and Cat6a cables are stricter than those for Cat5 and Cat5e wires. They are better protected and offer much faster data speeds over longer distances than Cat5 and Cat5e.

Q3. Which is better, Cat5 or Cat6 or Cat7?

CAT 5 is 100 MHz and can send data at up to 1000 Mbps.

Q4. How fast is Cat5 vs Cat6?

At a frequency of 250MHz, CAT6 can handle up to 1000 Mbps (1GbE).

Q5. Can I use Cat 6 instead of Cat 5?

There is a standard twisted pair line for Ethernet called CAT6. It works with CAT5/5e and CAT3 cables. CAT6 cables can handle Gigabit Ethernet segments up to 100 m, just like CAT5e cables can. They can also be used in 10-gigabit networks over a short distance.

Q6. Can Cat5 run 1000 Mbps?

Cat5e can handle speeds of 10Mbps, 100Mbps, or 1000Mbps for networks.

Final Thoughts

Even though Ethernet cables aren’t the most interesting technology, knowing the difference between them can save you money and time.
