Selection Criteria

Cable Category

Ethernet cables are classified into categories, commonly abbreviated as "Cat", which determine their performance capabilities. Here are the most common categories:

  • Cat 5e: Supports up to 1 Gbps and is suitable for most standard home applications.
  • Cat 6: Supports up to 10 Gbps over short distances (up to 55 meters) with better protection against interference.
  • Cat 6a: Extends Cat 6 capabilities to 10 Gbps over 100 meters, ideal for business networks.
  • Cat 7 and Cat 8: Support speeds of 10 to 25/40 Gbps respectively, with superior shielding to minimize interference. Perfect for infrastructures requiring very high performance.

Cable Length

The length affects signal strength. Choose a length just sufficient to reach your equipment to minimize potential losses. Cat 6 and higher cables maintain performance over longer distances.

Type of Shielding

Shielding prevents electromagnetic interference and radio frequency interference:

  • UTP (Unshielded Twisted Pair): Unshielded, suitable for home use with little environmental interference.
  • STP (Shielded Twisted Pair): Shielded, recommended for environments prone to interference.
  • FTP (Foiled Twisted Pair): Offers shielding against external interference for each wire pair, ideal for industrial settings.

Connectors

Ensure that the connectors are well reinforced and gold-plated for better conductivity and to prevent corrosion. A good connector ensures stable and reliable data transmission.

Common Mistakes

Choosing the Wrong Category

Selecting an inappropriate category for the intended use can limit your network's performance. Ensure the cable meets the speed and bandwidth requirements of your equipment.

Ignoring the Installation Environment

Ignoring environmental conditions can lead to malfunctions. Use shielded cables in environments with high levels of electromagnetic interference.

Underestimating Compatibility

Before purchasing, verify that your network devices (like routers and switches) are compatible with the chosen Ethernet cable category to avoid ports that limit performance.

Practical Tips

Anticipating Future Developments

To anticipate future technological developments or your needs, choose a cable with a slightly higher category than your current needs. This will prevent you from having to replace cables during a future network upgrade.

Outdoor Use

For cables installed outdoors, opt for cables with UV and water-resistant sheathing to prevent rapid deterioration.

Test After Installation

Once the cable is installed, test your network to ensure that the expected transfer speeds are indeed reached. Use network diagnostic tools to detect any potential issues.

FAQ

Shielding protects cables from electromagnetic interference, which is crucial in high-interference environments to ensure a stable and fast connection.

For a connected home, a Cat 6 or Cat 6a cable is generally sufficient, offering a good balance between performance and cost for speeds reaching up to 10 Gbps.
