What Are Network Cables and Why Do They Matter?
Network cables, also known as LAN cables or Ethernet cables, transmit data between routers, switches, computers, and other devices. Unlike Wi-Fi, they offer a low-interference, secure, and extremely fast connection. Modern cables support speeds from 1 Gbit/s up to 40 Gbit/s and beyond.
The main types are patch cables (for short connections) and installation cables (for permanent building wiring). At eKabel24 you will find a wide selection of high-quality network cables.
Network Cable Categories Explained
Network cables are divided into categories (Cat) that differ in bandwidth, speed, and shielding. Here is a detailed comparison:
| Category | Max. Frequency | Max. Speed | Typical Shielding | Best Use |
|---|---|---|---|---|
| Cat5e | 100 MHz | 1 Gbit/s | U/UTP | Home networks, basic offices |
| Cat6 | 250 MHz | 1 Gbit/s (10 Gbit/s up to 55m) | U/UTP or F/UTP | Modern home and office networks |
| Cat6a | 500 MHz | 10 Gbit/s | F/UTP or S/FTP | Professional installations |
| Cat7 | 600–1000 MHz | 10 Gbit/s | S/FTP (PIMF) | High-performance networks, future-proof |
| Cat8 | 2000 MHz | 25–40 Gbit/s (short distances) | S/FTP | Data centers, high-end applications |
At eKabel24, the focus is on premium Cat7 network cables that offer excellent shielding and durability.
Patch Cables vs Installation Cables – Which Do You Need?
- Patch Cables: Pre-terminated cables with RJ45 connectors for short distances (e.g. router to PC). Flexible and easy to use.
- Installation Cables: Raw cables for permanent installation in walls, ducts, or floors. Often available by the meter.
Shielding Types Explained
Shielding protects against electromagnetic interference (EMI):
- U/UTP: Unshielded – suitable for simple applications.
- F/UTP: Overall foil shield.
- S/FTP: Overall shield + individual pair shielding – offers the highest interference resistance.
Practical Buying and Installation Tips
When choosing a network cable, consider the following:
- Required speed and distance
- Environmental conditions (indoor/outdoor, interference sources)
- CPR fire rating
- Copper quality (pure copper instead of CCA)

Detailed Comparison Table
| Criteria | Cat6 | Cat6a | Cat7 |
|---|---|---|---|
| Frequency | 250 MHz | 500 MHz | 600–1200 MHz |
| 10 Gbit/s Distance | ~55 m | 100 m | 100 m |
| Shielding | Optional | High | Very High (S/FTP) |
| Future-Proofing | Good | Very Good | Excellent |
Frequently Asked Questions (FAQ) about Network Cables
Which network cable for 10 Gbit/s?
Cat6a or better Cat7. Cat7 also provides excellent shielding for stable connections.
What is the difference between patch cables and installation cables?
Patch cables are pre-terminated with connectors for short distances. Installation cables are raw cables for permanent wiring.
Is Cat7 backward compatible?
Yes, Cat7 cables work with all older devices and routers (Cat5e/Cat6).
What shielding is typical for Cat7?
S/FTP with PIMF (pair in metal foil).
Can I crimp network cables myself?
Yes, with the right tools and RJ45 connectors. For installation cables, pre-made patch cables or professional installation is often recommended.
Which cable for outdoor use?
Special outdoor or direct burial cables with PE jacket.
Conclusion: For most current and future applications, a Cat7 network cable is the best choice. Visit Ekabel24 Network Cables and benefit from high quality and custom solutions.
