How to choose an Ethernet cable

Choosing the Right Ethernet Cable

The unassuming Ethernet cable is the backbone of wired internet connections. But with various categories and specifications, choosing the right one can seem daunting. Fear not! This guide will equip you with the knowledge to navigate the ethernet cable landscape and select the perfect cable for your needs.

Understanding Cable Categories:

Ethernet cables are categorized based on their maximum supported speed and bandwidth. Here’s a breakdown of the most common categories:

  • Cat 5: The granddaddy of Ethernet cables, Cat 5 supports speeds up to 100Mbps. While sufficient for basic internet browsing, it’s generally outdated for modern internet plans.
  • Cat 5e: An improved version of Cat 5, Cat 5e offers better performance and is the current industry standard for most home networks. It supports speeds up to 1Gbps (gigabit per second).
  • Cat 6: Designed for higher speeds and data transfer, Cat 6 cables can handle up to 10Gbps over shorter distances (around 55 meters).
  • Cat 6a: An upgrade to Cat 6, Cat 6a cables offer improved performance over longer distances (up to 100 meters) and are ideal for future-proofing your network for potential speed upgrades.
  • Cat 8: The top dog of Ethernet cables, Cat 8 boasts exceptional performance and can support up to 40Gbps speeds. However, it’s overkill for most home users and significantly more expensive.

Choosing the Right Cable for You:

  • Match Your Needs to the Cable’s Speed: Consider your current internet plan’s speed and potential future upgrades. If you have a gigabit internet plan (or plan to get one soon), Cat 5e is sufficient. For future-proofing or 10Gbps speeds, Cat 6a is a good choice.
  • Cable Length: Keep in mind that cable performance can decrease over long distances. If you need a long cable run, consider Cat 6a for better performance over extended lengths.
  • Shielding: Unshielded Twisted Pair (UTP) cables are the most common and affordable option for home use. Shielded Twisted Pair (STP) cables offer better protection against interference but are typically more expensive and less flexible. UTP is perfectly suitable for most home environments unless you have significant electromagnetic interference.

Additional Considerations:

  • Durability: Look for cables with a PVC jacket for better protection against wear and tear.
  • Price: Cable price increases with category. Choose a cable that meets your needs without breaking the bank.


  • Cat 5e is the current standard for most home networks.
  • Cat 6a offers future-proofing for potential speed upgrades.
  • Match cable category and length to your internet speed and needs.
  • UTP cables are suitable for most home environments.

By understanding cable categories and considering your internet plan and setup, you can confidently choose the right Ethernet cable for optimal performance and a smooth internet experience.
