Different ethernet cable shielding types explained

Ethernet cables also differ by shielding type, affecting their performance in environments prone to interference:

• UTP (Unshielded Twisted Pair):
  • No extra shielding, economical, suitable for home and small office environments.
  • Popular brands: NETGEAR, Philips, Insignia.
• FTP (Foiled Twisted Pair):
  • Includes aluminum foil shielding around the cable pairs, offering basic interference protection.
  • Common brands: Belkin, GearIT.
• STP (Shielded Twisted Pair):
  • Individual cable pairs shielded, plus overall cable shielding. Reduces electromagnetic noise, ideal for professional installations.
  • Recommended brands: Ugreen, StarTech.
• SFTP (Shielded Foiled Twisted Pair):
  • Combines individual pair shielding with overall cable shielding. Maximum interference protection, suitable for high-performance setups.
  • Highly recommended brands: FS.COM, Monoprice.

Solid vs. Stranded ethernet cable

Depending on your usage scenario, selecting between solid or stranded Ethernet cables can impact durability and performance:

• Solid Ethernet Cable:
  • Features a single, solid copper conductor.
  • Ideal for structured cabling in walls or fixed installations. Best for long distances.
• Stranded Ethernet Cable:
  • Made from multiple thin copper strands twisted together.
  • Ideal for flexible, movable cables like patch cords or short-distance desktop connections.

Pro tip from Ciegate Technologies:
For professional office or home installations, we highly recommend solid Ethernet cables combined with expert installation. Ciegate Technologies provides professional network audits and installation services to ensure your Ethernet investment delivers long-term performance and reliability.

Copper vs. CCA ethernet cables and AWG (American Wire Gauge) explained

Copper vs. CCA ethernet cables: Which is best?

When selecting Ethernet cables, you’ll find two primary conductor materials: 100% Copper and Copper-Clad Aluminum (CCA). The choice between these two significantly affects performance, safety, and reliability:

Advantages of 100% Copper ethernet cables:

• Superior Conductivity: Pure copper cables provide maximum data transmission speeds and minimal electrical resistance.
• Reliable PoE (Power over Ethernet) Support: Safely powers devices like IP cameras, VoIP phones, and network equipment without overheating risks.
• Long-lasting Durability: Highly resistant to corrosion, making them ideal for permanent and professional installations.

Top Brands for 100% Copper Cables: NETGEAR, StarTech, Monoprice, FS.COM.Advantages of CCA (Copper-Clad Aluminum) Ethernet Cables:

• More Economical: Lower initial cost due to aluminum’s affordability compared to copper.
• Lightweight and Flexible: Easier to handle for temporary setups or simple residential installations.

Important Disadvantages:

• Reduced performance at longer cable lengths.
• Potential safety risks when used in PoE applications due to overheating.
• Higher susceptibility to interference and signal degradation.

Professional Recommendation from Ciegate Technologies:
For reliable, long-term network installations, always opt for 100% pure copper Ethernet cables. While the upfront investment is slightly higher, the performance, durability, and safety benefits greatly outweigh the initial savings. As network installation experts, Ciegate Technologies can professionally install high-quality copper cables to ensure your network performs optimally for years to come.

What is AWG (American Wire Gauge)?

AWG stands for “American Wire Gauge” and indicates the conductor thickness within the cable. A lower AWG number means a thicker conductor, indicating higher quality and lower signal loss over distance:

• 22–24 AWG: Recommended for permanent, long-distance, professional installations. Offers excellent performance, lower resistance, and better signal stability.
• 26–28 AWG: Ideal for shorter cables, patch cords, and home scenarios where flexibility matters.

Recommended Ethernet Cable (Top Choice):
The Surplay CAT8 Ethernet Cable offers premium 26 AWG pure copper conductors for unmatched performance up to 40Gbps. Perfectly suited for gaming, data centers, and demanding office/home users needing ultra-high speeds and reliability.

Community insight — What Reddit users say

What the community Is saying about ethernet cables

Choosing the best Ethernet cable isn’t just about technical specs—it’s also about real-world results. According to a top-rated thread in the r/HomeNetworking subreddit, users agree that:

“Cat6a is the best balance between performance and cost,”
especially for home users who want long-term reliability without overspending.

Other community members point out that while Cat8 might seem like overkill for most home setups, it’s a smart choice for future-proofing, especially when you’re gaming, transferring large files locally, or using high-speed fiber internet.

This aligns perfectly with Ciegate Technologies’ recommendation: choose the cable that not only fits your current setup—but one that supports your network’s evolution.

People also ask

What is the highest quality Ethernet cable?

The highest quality Ethernet cable currently available is Cat8. It supports up to 40Gbps of data transfer and a bandwidth of 2000MHz, making it ideal for data centers, high-speed gaming, and enterprise-grade networking. It also features advanced shielding for maximum interference protection, ensuring top performance in demanding environments.

Is Cat8 better than Cat6?

Yes, Cat8 is significantly better than Cat6 in terms of speed and shielding. While Cat6 supports up to 10Gbps at shorter distances, Cat8 can handle 40Gbps, offers much higher bandwidth (2000MHz vs 250MHz), and provides superior protection against crosstalk and EMI. However, Cat6 is more cost-effective and sufficient for most home and small business setups.

---

Is Cat7 or Cat8 better?

Cat8 is better than Cat7 in nearly all aspects. Although both offer excellent shielding, Cat8 supports higher speeds (40Gbps) and greater bandwidth (2000MHz) compared to Cat7’s 10Gbps and 600MHz. Cat8 also uses modern connectors (RJ45 or GG45) compatible with existing infrastructure, making it more future-proof and efficient for high-performance use.

---

Is Cat6 or Cat7 better for gaming?

Cat7 is generally better for gaming due to its enhanced shielding and support for higher bandwidth (600MHz vs 250MHz on Cat6), reducing interference and ensuring more stable connections. However, for most gamers, Cat6 is still very capable, especially for setups that don’t require extreme performance or ultra-low latency.
