When building or upgrading a network — whether for an ISP, enterprise office, or data centre — one of the most common questions is: which cable standard should I use? Cat6, Cat6A, and Cat7 all promise better performance than their predecessors, but the differences between them matter enormously for cost, installation complexity, and real-world performance. This guide breaks it all down clearly.
Cat6: The Workhorse of Modern Networking
Cat6 (Category 6) is the current mainstream standard for Ethernet cabling in homes, offices, and ISP deployments. It supports:
- 1Gbps at up to 100 metres — the standard for most installations
- 10Gbps at up to 55 metres — useful for short high-speed server or aggregation runs
- 250MHz bandwidth (or 550MHz for enhanced Cat6 variants)
Cat6 uses standard RJ45 connectors, is widely available, and is significantly more affordable than Cat6A or Cat7. For the vast majority of ISP customer premises equipment (CPE) installations, last-mile links, and office LANs across Uganda and East Africa, Cat6 is the right choice. Our most popular Cat6 options include the Cat6 1000Mbps High-Speed LAN Cable for standard patch runs and the Vention Cat6 Patch Cable (Multi-Colour) for colour-coded NOC and patch panel deployments.
Cat6A: The 10Gbps Full-Distance Solution
Cat6A (Category 6 Augmented) was designed to solve one specific problem: running 10Gbps over the full 100-metre distance. It supports:
- 10Gbps at up to 100 metres — the key advantage over standard Cat6
- 500MHz bandwidth — double the standard Cat6 specification
- Available in both UTP and shielded (STP/SFTP) variants
The trade-offs are real: Cat6A cables are significantly thicker and heavier than Cat6, making them harder to route through conduit and tight spaces. They are also considerably more expensive per metre. For ISP core infrastructure, data centre horizontal cabling, and enterprise server rooms requiring 10Gbps over full-length runs, Cat6A is the right investment. The closest option in our range for high-speed shielded applications is the Cat6 Shielded 10Gbps Gold-Plated RJ45 Cable — delivering 10Gbps performance with full shielding at a practical cost point.
Cat7: High Specs, Low Adoption
Cat7 (Category 7) looks impressive on paper:
- 10Gbps at up to 100 metres
- 600MHz bandwidth
- Fully shielded (S/FTP) — every pair individually shielded plus an overall screen
However, Cat7 has a significant problem: it is not an IEEE-ratified standard. It uses proprietary GG45 or TERA connectors that are not compatible with standard RJ45 equipment. This means your switches, routers, patch panels, and wall plates would all need to be replaced. In practice, almost no enterprise or ISP network in East Africa uses Cat7 — Cat6A achieves the same 10Gbps at 100 metres with standard RJ45 connectors and at lower cost.
Side-by-Side Comparison
| Feature | Cat6 | Cat6A | Cat7 |
|---|---|---|---|
| Max speed | 10Gbps (55m) / 1Gbps (100m) | 10Gbps (100m) | 10Gbps (100m) |
| Bandwidth | 250–550MHz | 500MHz | 600MHz |
| Connector | RJ45 | RJ45 | GG45 / TERA (proprietary) |
| Shielding | UTP or STP | UTP or STP | S/FTP (fully shielded) |
| Cost | Low | Medium–High | High |
| ISP adoption | Very High | Medium | Very Low |
Which Should You Choose?
Here's our practical recommendation for ISPs and businesses in Uganda and East Africa:
- ISP last-mile and CPE installations: Dutevolns Cat6 Indoor/Outdoor UTP 24AWG or Cat6 Outdoor 250ft UV-Resistant — cost-effective, weatherproof, and delivers 1Gbps reliably.
- Office LANs and structured cabling: Cat6 1000Mbps LAN Cable — the right balance of performance and cost for most businesses.
- Bulk ISP infrastructure and large structured cabling projects: Cmple Cat6 Bulk 1000ft 23AWG 550MHz Reel — pull through conduit for backbone and distribution runs.
- Data centres and server rooms requiring 10Gbps over full 100m runs: Cat6 Shielded 10Gbps Gold-Plated RJ45 — the professional standard for high-speed shielded links.
- Short 10Gbps runs under 55 metres: Cat6 at 550MHz — saves significant cost over Cat6A for aggregation and core switching.
- Cat7: Not recommended for new ISP or enterprise deployments due to connector incompatibility and low industry adoption.

Final Thoughts
For most ISPs and businesses in Uganda and East Africa, Cat6 remains the smartest investment — delivering reliable gigabit performance at the lowest cost. Cat6A is the right step up when you need full-distance 10Gbps. Cat7 is largely a marketing specification with real-world compatibility problems that make it impractical for standard deployments.

Frequently Asked Questions (FAQ)
Q: What is the difference between Cat6 and Cat6A?
A: Cat6 supports 1Gbps at up to 100 metres and 10Gbps at up to 55 metres. Cat6A supports 10Gbps at the full 100-metre run length with a 500MHz bandwidth rating, but is thicker and more expensive. For most ISP deployments, Cat6 is sufficient — browse our Cat6 cable range at NetEdge Supplies.
Q: Is Cat7 better than Cat6A?
A: Cat7 has higher specifications but is not an IEEE-ratified standard and uses proprietary connectors incompatible with standard RJ45 equipment. For most ISP and enterprise deployments, Cat6A is the preferred and more practical choice for 10Gbps. Our Cat6 Shielded 10Gbps delivers equivalent performance with standard RJ45 connectors.
Q: Which cable is best for ISP last-mile deployments in Uganda?
A: For most ISP last-mile and CPE deployments in Uganda, the Dutevolns Cat6 Indoor/Outdoor UTP 24AWG or Cat6 Outdoor 250ft UV-Resistant are the most cost-effective and practical choices — delivering reliable 1Gbps performance in outdoor conditions.
Q: Do I need Cat6A for a server room or data centre?
A: If your server room requires 10Gbps over runs longer than 55 metres, choose the Cat6 Shielded 10Gbps Gold-Plated RJ45. For shorter 10Gbps runs under 55 metres, standard Cat6 at 550MHz is sufficient and more cost-effective.
Q: Is Cat6 backward-compatible with Cat5e?
A: Yes. Cat6 is fully backward-compatible with Cat5e and Cat5 infrastructure, including existing switches, routers, and wall ports — no need to replace other equipment. Browse our full Cat6 cable range at NetEdge Supplies.
Q: Where can I buy Cat6 cables in Uganda?
A: NetEdge Supplies stocks a full range of Cat6 cables in Uganda — indoor patch cables, outdoor UV-resistant cables, flat cables, and bulk reels. We deliver across Uganda and East Africa.
