The right Ethernet cable is essential to create a successful home or office network. While shopping for network cables, you would likely have come across a few terms that you are not familiar with, such as Cat5e and Cat6. Let’s take a closer look at Cat5e Ethernet cables and Cat6 Ethernet cable and what they are, so you can make a prudent decision.
To gain an understanding of Ethernet Cable Categories.
Ethernet cables come in different categories that are based on their specifications and the amount of performance that they are able to provide. The “Cat” is the “category” and the number represents the generation as well as the performance level. With each category, the capabilities become greater, such as improved data transmission speeds, increased shielding and signal integrity.

Cat5e: The Affordable Workhorse available.
Cat5e (Category 5e) cables are improved quality of the original Cat5 cables. It has been a no-brainer for networking for almost 20 years, and still is the most widely installed network cable around the world.
Specifications and Performance
Cat 5e cables are made of four sets of twisted pairs of copper wire with insulation and colour coding provides the proper installation procedure. The “e” signifies enhanced, which means that the crosstalk is enhanced in comparison to the original Cat 5 standard. Cat5e is capable of carrying data at speeds up to 1Gbps (Gigabit per second) across up to 100 meters or sufficient for the majority of home and small business needs.
When to Use Cat5e
Cat5e is an ideal choice for an average broadband connection, as well as for small office systems, regular Internet usage, e-mail, video streaming, and economical installations in the home network. It’s affordable, available, simple installation and terminating and works with older equipment. However Cat 5e has a max speed of 1 Gbps, is prone to crosstalk and is not ideal for future-proofing or high interference environments.
Cat6: The Premium Performer
Cat6 (Category 6) is the more modern standard, which has advanced the ethernet cable technology. These cables were issued in 2001, making them suitable for high-speed networks.
Specifications and Performance
Cat6 cables are thicker-banded, also have further covering and feature 4 twisted pairs of copper wire. Some Cat6 cables are fitted with a plastic separator between wire pairs which further minimises crosstalk. With the improved construction comes greater electromagnetic shielding and overall signal integrity. Cat6 can provide speeds of up to 10 Gbps (10 Gigabits per second) and distance of up to 55 meters (180 feet). Cat6, over the entire 100 m length, can consistently achieve 1 Gbps speeds over 10 m away (10 times the bandwidth of Cat5e).
When to Use Cat6
Cat6 is the best choice for gigabit networking, professional offices, video producers, future-proof networking installations and gaming set-ups for maximum bandwidth. Cat6 is faster at 10Gbps, offers more shielding and delivers superior crosstalk reduction and is the investment in the future. It is more expensive, is thicker and stiffer of construction and needs expert termination for best performance, however.
There are some differences between Cat5e and Cat6.
Speed and Bandwidth
The biggest differences are in performance. Cat5e Ethernet cables can reach speeds of up to 1Gbps while Cat6 Ethernet cables can reach up to 10Gbps. This is 10 times more bandwidth when it comes to data transmits.
Frequency Range
Cat5e would be considered at 100 MHz just enough for 1 Gbps performance. Cat6 can carry up to 10 Gbps data rates at 250MHz.
Distance Limitations
Cat5e is very reliable up to 100 meters because it can reach its full performance of 1 Gbps. Cat6 is capable of providing all 10GB of bandwidth up to 55 meters away, but can deliver 1GB of bandwidth reliably up to and beyond 100 meters.
They have good rejection properties.
They have high rejection and Crosstalk reduction properties.
Cat5e has a weak shield and has crosstalk reduction by twisted pair technology. Cat6 provides greater level of protection against Crosstalk and EMC through the use of improved shielding factor using plastic separators between wire pairs.
Cost and Installation
Easy to install, Cat5e Cables come in at much lower price than traditional Cat5 cables. Cat6 is thicker, harder and more expensive than Cat5, and must be installed professionally and often ends in professional termination.
Real-World Impact
It will depend on your needs to see any practical implications. Those who are using the web, receiving emails, or watching videos on the normal internet (usually 1 Gbps) won’t feel the difference. When you need to transfer large files at 3 times the speed across your LAN or have a media server or a professional desktop, however, Cat6’s 10Gbps is worth a lot.
Making Your Choice
If you have an internet speed of 1Gbps or slower, your network’s purpose is just to get your home up and running, you’re on a budget, and you don’t need future-proofing, then opt for Cat5e.
Select Cat6 for future-proof capability, high-speed fiber or gigabit internet, often transfer large files locally or setting up a professional network in an environment with electromagnetic interference.
Whether using Cat5e or Cat6, the key to getting the most from your Ethernet cables is proper cable management and installation. Even with the best Cat6 cable, it is important to install your cables away from areas with power lines, electric equipment, or sources of electromagnetic interference, as this can impact signal quality. Keep your network cables organized and protected from physical damage, pinching or accidental cuts with cable clips, conduits or cable trays.
With Cat6 cables, use a minimum bend radius of 1 inch or more to avoid damage and loss of signal. Also, make sure to use quality RJ45 connectors for the job and use industry standard colour coding for wire arrangement. If you routinely check your cables for deterioration, you should be able to find problems before they affect your network performance. These additional measures on the installation will make your ethernet investment last for years of trouble free connectivity.
The Bottom Line
Cat5e and Cat6 are not the same. With many people having standard broadband, Cat5e is still seen as a good budget option. Cat6 is best suitable if you are investing for the future, or using it for high-speed data transfer locally. They’re compatible with each other as they use the same RJ45 connectors and they’re backward compatible. Regardless of the choice, buy high-quality cables from reputable manufacturers and ensure they are connected correctly to ensure a stable and reliable network.
