Fiber optic broadband speed

Fibre optic broadband can deliver speeds from 100 Mbps up to 1 Gbps or more, with low latency and stable performance for high-demand online activities.

Typical Speeds

Fibre optic broadband is significantly faster than older copper-based connections. In the UK, full fibre connections can reach hundreds of Mbps, with some providers offering speeds up to 900 Mbps for download and similar upload rates . Standard fibre packages often range from 100 Mbps to 500 Mbps, which is sufficient for streaming 4K video, online gaming, and multiple users simultaneously .

Latency and Jitter

Latency, measured in milliseconds (ms), indicates how quickly data travels between your device and the server. Fibre connections typically have latency under 30 ms, which is excellent for real-time applications like gaming or video calls . Jitter, the variation in latency, is usually under 5 ms on fibre, ensuring smooth voice and video communication .

Factors Affecting Speed

Actual speeds can vary due to several factors:

• Connection type: Full fibre is faster than hybrid fibre-copper (FTTC) or ADSL .
• Router and device: Using an Ethernet cable instead of Wi-Fi improves speed and stability .
• Network congestion: Speeds may drop during peak usage times.
• Distance and obstacles: Thick walls or long Wi-Fi range can reduce wireless performance .

Testing Your Fibre Speed

To accurately measure your broadband speed:

1. Connect your device directly to the router via Ethernet.
2. Pause other downloads or streaming activities.
3. Use reliable speed test tools like Which? Broadband Speed Test, UKSpeedTest, or Uswitch Broadband Speed Test .
4. Test at different times of day to get an average performance reading.

Practical Considerations

• Light usage (web browsing, emails, standard streaming): 20–50 Mbps is sufficient.
• Heavy usage (4K streaming, gaming, multiple users): 100–500 Mbps or higher is recommended.
• High-end fibre (up to 1 Gbps): Ideal for large households, home offices, or content creators needing fast uploads and downloads . Fibre optic broadband provides high-speed, low-latency, and reliable internet, making it the preferred choice for modern households and businesses requiring consistent performance.
