What Is a Cat 7 Ethernet Cable?

A Cat 7 Ethernet cable (Category 7) is a high-performance networking cable designed for high-speed data transmission. It supports frequencies up to 600 MHz and speeds of up to 10 Gbps over 100 meters, making it ideal for data-intensive environments.

This cable is especially popular in enterprise networks, home theaters, gaming setups, and data centers that demand low latency and minimal interference.

Key Features of Cat 7 Ethernet Cables

  • Shielded Twisted Pair (S/FTP): Each twisted pair is shielded, plus an overall shield for the cable—minimizing electromagnetic interference (EMI).

  • High Bandwidth: Up to 600 MHz transmission frequency, allowing stable connections for 10G networks.

  • Backward Compatibility: Works with Cat 6, Cat 5e, and older Ethernet standards.

  • Improved Durability: Thicker cable insulation and gold-plated connectors ensure longer lifespan.

Applications for Cat 7 Cables

Cat 7 is widely used in:

  • Home networks with streaming and gaming devices

  • Offices with high data throughput requirements

  • Data centers connecting servers and switches

  • Smart homes powering IoT devices

  • Industrial environments with lots of EMI

Cat 7 vs Cat 6 and Cat 6a: What’s the Difference?

Feature Cat 6 Cat 6a Cat 7
Max Speed 1 Gbps 10 Gbps 10 Gbps
Frequency 250 MHz 500 MHz 600 MHz
Shielding UTP/STP UTP/STP Always Shielded
EMI Protection Moderate High Excellent
Use Case Home/Office Pro Office Data Centers, Servers

How to Choose the Right Cat 7 Ethernet Cable

When buying a Cat 7 cable, consider the following:

  • Length needed (shorter = better signal)

  • Shielded connectors (look for S/FTP types)

  • Cable thickness (22-24 AWG preferred)

  • Certifications (check for ISO/IEC 11801 Class F)

  • Gold-plated connectors for corrosion resistance

Is Cat 7 Future-Proof?

While Cat 7 is not officially recognized by TIA/EIA standards, it is widely used in Europe and many industries as a next-gen solution. For users preparing for 10G networking or shielding-heavy environments, it’s a solid investment. However, Cat 8 is emerging for 25G–40G networks, so choose according to your actual needs.

Where to Buy Cat 7 Ethernet Cables

You can find Cat 7 cables from brands like:

  • UGREEN

  • Cable Matters

  • Jadaol

  • Amazon Basics

  • Monoprice

Ensure you're buying from a reputable supplier with return policies and certifications.

Conclusion: Should You Upgrade to Cat 7?

If you're building a network that demands high speed, durability, and low interference, Cat 7 Ethernet cables are a strong choice. They offer excellent performance and shielding, making them ideal for modern smart homes, offices, and tech-heavy environments.
