What’s the Best Ethernet Cable?

An Ethernet cable can help you enjoy seamless streaming of your favorite shows or reach the leader board of your favorite competitive online game. Known for their speed and reliability, Ethernet cables are encased sets of wires that allow data to travel between your computer and your router or modem. If you work from home and require a reliable connection, an Ethernet cable provides more security than a Wi-Fi connection.

Not all Ethernet cables are equal, and finding the right cable requires a bit of homework. In this guide, we’ll review various Ethernet cable options to help you make the right choice for your needs.

What are the different types of Ethernet cables?

If you recently switched to a faster internet plan and upgraded your modem to find you’re not getting the performance you expect, your Ethernet cable may be the crux of the problem. Using an outdated Ethernet cable can prevent you from achieving today’s fast speeds, so an upgrade may be in order.

When shopping for Ethernet cables, you’ll see them labeled with “Cat,” which is short for “category,” along with a number. Generally speaking, cables with higher numbers support faster speeds.

Cat 5e

Cat 5e cables are the most inexpensive but lowest-grade Ethernet cables in the marketplace today. While a Cat 5e cable can support line speeds of up to 1000Mbps (megabits per second) and bandwidth up to 100MHz, this cable is best for those who don’t have serious performance demands.

Cat 6

A Cat 6 cable is more expensive to produce than a Cat 5e and comes at a higher cost. It supports transfers up to 1000 Mbps but has a slightly higher bandwidth at 250GHz, making it an option for mid-level gaming and video calling. This cable relies on foil or braided shielding to avoid crosstalk.

Cat 6a

This is the augmented version of Cat 6, hence the “a” designation. It supports double the bandwidth and with its thicker coating, and there is virtually no crosstalk with these cables. Cat 6 and 6a cables are popular among those who require support for streaming.

Cat 7

These are high-performance cables designed to support higher speeds. However, due to the nature of the proprietary technology of the design, costs run higher. These cables are currently used in specific applications and are not yet considered mainstream Ethernet cables.

Cat 8

Earmarked for those who require top performance, these cables can support up to 30Gbps (gigabits per second) and 2000MHz. While this may seem excessive, these cables could be a good fit for those who run through cables quite frequently and require greater durability.
