High-Speed Networking Guide
What Type of Network Cabling Is Best for High-Speed Business Networks?
“High-speed” means different things at a desk, an access point, and a backbone. The best cabling for a fast business network isn’t one cable everywhere; it’s the right cable for each part of the network. Here’s how Cat6, Cat6A, Cat8, and fiber compare, and which to choose for each connection.
What Does “High-Speed” Mean for a Business Network?
A business network has several layers, and each one has different speed needs. Desks connect at 1 Gbps or more. Modern Wi-Fi access points use multi-gigabit uplinks of 2.5, 5, or 10 Gbps. Workstations for video editing, design, and imaging may need 10 Gbps. The backbone between telecom rooms, floors, and servers carries the combined traffic of everyone, often at 10, 25, 40, or 100 Gbps.
The best cabling matches each of those layers. At Network Cabling Company Glendale, we design high-speed networks by starting with what each connection needs today and what it will likely need after the next equipment upgrade.
| Part of the network | Typical speed today | Speed to plan for |
|---|---|---|
| Desks and VoIP phones | 1 Gbps | 1–2.5 Gbps |
| Wi-Fi access points | 1–5 Gbps | 5–10 Gbps |
| High-demand workstations | 1–10 Gbps | 10 Gbps |
| Switch uplinks and backbones | 10 Gbps | 25–100 Gbps |
| Servers and storage | 10–25 Gbps | 25–100 Gbps |
Comparing the Main Cable Options
| Cable type | Speed and distance | Best use |
|---|---|---|
| Cat5e | 1 Gbps to 100 m | Existing plants only; not recommended for new installations |
| Cat6 | 1 Gbps to 100 m; 10 Gbps to about 55 m | Desks, phones, printers, and POS |
| Cat6A | 10 Gbps to 100 m | Access points, cameras, workstations, and future-ready horizontal cabling |
| Cat8 | 25–40 Gbps to 30 m | Short links between switches and servers in data centers |
| OM4 multimode fiber | 10 Gbps to 400 m; 100 Gbps to 150 m | In-building backbones and server links |
| OS2 single-mode fiber | 10 Gbps to 10 km and beyond; supports 100 Gbps and higher | Building-to-building links, long backbones, and carrier entry |
Why Cat6A Is the Best Copper Choice for Most Businesses
For the copper cabling that runs from telecom rooms to devices, Cat6A offers the best balance of speed, distance, and cost. It carries 10 Gbps across the full 100 m, so every run on a floor supports the same top speed, no matter how far it is from the rack. Industry guidance increasingly points to Cat6A as the preferred choice for new horizontal cabling, and it’s the recommended cable for Wi-Fi access points.
Cat6A also handles high-power PoE better in large bundles, which matters as access points, cameras, and displays draw more power. For businesses planning to stay in a space for years, it’s the cable most likely to support the next two or three rounds of equipment without rewiring.
Choose Cat6A for
- Wi-Fi 6E and Wi-Fi 7 access points.
- 10 Gbps workstations for editing, design, and imaging.
- High-power PoE cameras and displays.
- Runs longer than about 55 m that need 10 Gbps.
- New builds and long-term leases.
Where Cat6 still fits
Cat6 remains a sound, lower-cost choice for devices that connect at 1 Gbps, such as standard desks, phones, printers, and POS terminals. Many businesses use Cat6 for those connections and Cat6A for access points and high-demand devices.
Why Fiber Is Best for Backbones and the Highest Speeds
Once speeds climb past 10 Gbps, or distances go beyond 100 m, fiber takes over. It carries data as light, isn’t affected by electrical interference, and supports 25, 40, 100 Gbps and beyond. A fiber backbone between the main equipment room and each telecom room keeps traffic from bottlenecking between floors.
Fiber also scales well. Moving from 10 to 100 Gbps on a fiber backbone usually means changing the switches and transceivers at each end, not pulling new cable. For multi-floor offices in Brand Boulevard and downtown Glendale towers, campuses, studios, and warehouses, a fiber backbone is the foundation of a high-speed network.
Multimode or single-mode?
OM4 multimode is the common choice for backbones inside a building, with 100 Gbps supported up to about 150 m. OS2 single-mode supports far longer distances and the highest speeds, so it’s used between buildings, for long risers, and for carrier connections. Some businesses install both in the backbone for flexibility.
What About Cat8?
Cat8 supports 25 and 40 Gbps, but only up to 30 m. It was designed for short connections between switches and servers inside data centers and server rooms, not for runs to desks or ceilings. For almost every office, Cat6A is the better copper choice for horizontal cabling, and fiber is the better choice for anything faster than 10 Gbps. Inside a rack, direct-attach copper or active optical cables are also common for short, very high-speed links.
The Best Cable for Each Part of Your Network
| Connection | Recommended cable | Why |
|---|---|---|
| Standard desks and phones | Cat6 or Cat6A | 1 Gbps devices, with Cat6A adding future headroom |
| Wi-Fi access points | Cat6A | Multi-gigabit uplinks and higher PoE power |
| IP cameras and displays | Cat6A | PoE power and reliable performance in bundles |
| High-demand workstations | Cat6A, or fiber for the fastest links | 10 Gbps at full distance |
| Floor-to-floor backbone | OM4 multimode or OS2 single-mode fiber | 10–100 Gbps between telecom rooms |
| Building-to-building links | OS2 single-mode fiber | Long distances and electrical isolation |
| Server and storage links | Fiber, DAC, or Cat8 for short runs | 25 Gbps and faster within the rack or row |
Future-Proofing Your High-Speed Network
Cable usually stays in the walls for 10 to 15 years or more, while switches and access points are replaced every few years. Choosing cabling with headroom now, like Cat6A to devices and a fiber backbone with spare strands, means each equipment upgrade delivers its full speed without new construction.
Speed is only one part of planning ahead. Spare drops, open patch-panel ports, and room in the pathways matter just as much when your team and technology expand. Learn more about how structured cabling can support business growth in Glendale, CA.
Details That Decide Real-World Speed
- Match every component. Jacks, patch panels, and patch cords must be rated for the same category as the cable, or the whole run performs at the lowest rating.
- Respect distance limits. Keep copper channels within 100 m, and use fiber beyond that.
- Install carefully. Tight bends, crushed bundles, and too much untwisting at terminations reduce performance, especially for Cat6A and fiber.
- Separate data from power. Keep copper runs away from electrical lines and interference sources.
- Keep fiber connectors clean. Dirty connectors are a common cause of fiber performance problems.
- Certify every run. Testing proves each run meets its rating and gives you a baseline for future troubleshooting.
Planning Your High-Speed Cabling Project
Once you know which cable belongs where, the next step is planning the installation around your business. Cat6A and fiber take more care to pull, terminate, and test than older cable, and commercial buildings in Glendale often have after-hours work windows, freight elevator bookings, and landlord approvals to schedule around. Build-outs also need cabling coordinated with other trades before walls and ceilings close.

Frequently Asked Questions
What is the fastest type of network cable?
Fiber optic cable supports the highest speeds and longest distances, with 100 Gbps and faster links in common use. Among copper cables, Cat8 reaches 25 to 40 Gbps, but only up to 30 m.
Is Cat6A fast enough for a business network?
Yes. Cat6A supports 10 Gbps to 100 m, which covers desks, Wi-Fi access points, cameras, and most high-demand workstations. Fiber is used for backbones and links faster than 10 Gbps.
Should I install Cat8 in my office?
Usually not. Cat8 is designed for short links of up to 30 m in data centers. Cat6A is the better choice for office runs to desks and ceilings.
Is Cat6 still good for business networks?
Yes, for 1 Gbps devices such as standard desks, phones, and printers. For access points and anything that needs 10 Gbps at full distance, Cat6A is the better long-term choice.
Do I need fiber for a high-speed network?
Most multi-floor offices, campuses, and high-bandwidth businesses benefit from a fiber backbone. A single-suite office with short runs may not need fiber inside the suite.
Will better cabling make my internet faster?
It won’t raise the speed of your internet plan, but it removes internal bottlenecks so every device can use the full speed you pay for.
