From legacy CAT5 to cutting-edge CAT8 and fibre — we specify, install, and certify structured cabling systems built to last.
Gemini Networks has been installing structured cabling since CAT5 was the standard. Today we work across the full range — from CAT5e for everyday connectivity to CAT8 for high-speed data centre inter-links.
Every installation is planned, managed, and certified. We work to structured cabling standards so your infrastructure is documented, testable, and ready to grow.
Choosing the right cable type saves money and future-proofs your infrastructure. Here is how the standards compare:
| Cable Type | Max Speed | Max Distance | Bandwidth | Best Use Case |
|---|---|---|---|---|
| CAT5 | 10 / 100 / 1000 Mb/s | 100 m | 100 MHz | General office connectivity — most common legacy install |
| CAT6 | 1 Gb/s (100 m) / 10 Gb/s (55 m) | 100 m / 55 m | 250 MHz | Improved performance offices, dual-speed environments |
| CAT6a | 10 Gb/s | 100 m | 500 MHz | High-performance offices and server rooms |
| CAT7 | 10 Gb/s | 100 m | 600 MHz | ⚠ Not TIA/EIA standard — proprietary connectors make it unsuitable for most structured cabling deployments |
| CAT8 | 40 Gb/s | 30 m | 2000 MHz | Data centre inter-links and server-to-switch connections |
| Wi-Fi | 10 Mb/s – 500 Mb/s | Varies | — | Point-to-point, multipoint, AP or mesh deployments |
| Fibre — Single-mode | 100 Gb/s | > 100 km | — | Long-distance, high-speed backbone and campus links |
| Fibre — Multi-mode | High | 300 – 550 m | — | Shorter distances, higher data volume, building-to-building links |
Ideal for distances over 100 km at speeds up to 100 Gb/s. Used for campus backbone, WAN links, and high-speed inter-building connections.
Covers 300–550 m at high data volumes. Lower cost than single-mode for shorter runs — commonly used between floors or buildings on a campus.
40 Gb/s over 30 m at 2000 MHz. The ideal choice for linking servers, switches, and storage in data centres and server rooms.
We will assess your requirements and recommend the optimal solution.
