Cat5E vs Cat6
“What? Seven minutes? That’s nothing, I can download it twice as faster.”
An Internet connection is something we can’t imagine living without because we use for everything from getting information to booking a flight to ordering food. And if you like online gaming, a fast and stable Internet connection is a must-have. Even though your Internet speed depends on the package you bought from your provider, it can also depend on the cables that the provider used in their network infrastructure.
Cat 5E and Cat6, also known as Category cables, are most commonly used in network cabling. They are suitable for 10-Gigabit Ethernet (10GBASE-T), provide a higher signal-to-noise ratio, and lower crosstalk. Let’s take a look at the differences and similarities between Cat5E vs Cat6 cables.
Tech Specifications and Price
The cost of Cat5E cables varies by manufacturer and length and you will probably get it for $0.20 to $0.30 per foot. Their frequency goes up to 100 MHz and the maximum cable length is 100m, their theoretical top speed is 1,000Mbps. And performance? They have less interference/crosstalk than Cat5 but more than Cat6.
Cat6 cables cost $0.40-$0.60 per foot and come in 55m max (for Gigabit Ethernet) and 100m max for network speeds of up to 1,000Mbps. Their frequency is up to 250 MHz, performance in SNR (signal-to-noise ratio) is higher, while their theoretical top speed is at 10Gbps.
Cat5E and Cat6 are backward compatible, which means that older Cat5E and Cat5 equipment can be used with newer Cat6 cables.
Both Cat5E and Cat6 are made of twisted pair cables with copper wire (with 4 twisted pairs in each cable). Cat6 have less noise and crosstalk, and provide a performance of up to 250 MHz. This was achieved by using a spline in the wiring which isolates each of the four pairs of wire. However, regardless of whether a spline is used as a separator, Cat6 cables provide a near crosstalk or lower electrical interference in the transmission. With Cat6, the data rates in the transmission are higher and there are fewer errors.
Cable specifications allow lengths no longer than 100m for both Cat5E and Cat6. However, when used for 10GBASE-T, Cat6 has a lower maximum length of 55m. If you want to run 10GBASE-T for 100m, you need to use Cat6A or Augmented Category 6 cable which allows performance of up to 500 MHz. The signal can be amplified with switches or repeaters if the distance longer than 100m needs to be covered in a network infrastructure.
The most common type of cable used for network deployments is Cat5E (“E” stands for “Enhanced”) because it can support higher speeds at a cost-effective price. And even though Cat6 offers a higher performance rate, many Ethernet networks still go for Cat5E. However, Cat6 use a thicker sheath for insulation that protects against Alien Crosstalk (AXT) and Near End Crosstalk (NEXT).
What is the best choice for you? Well, it all depends on what you’re trying to accomplish. Cat6 clearly has better specifications while Cat5E is widely utilized and cost-effective. So, Cat5E can definitely meet your needs for your home network. The speeds supported by Cat5E are likely faster than what your Internet connection can provide. Commercial users with high demands for fast Internet and internal speeds should opt for Cat6.
