Frequently Asked Questions

Find Quick Answers

How accurate is this fiber line tester?

The tool uses multiple test methods including simulated file transfers and network pings to provide accurate measurements of your actual connection performance.

Do I need to install anything to use this tool?

No installation required - the tool runs entirely in your browser with optional server-side enhancements for more accurate measurements.

What should my fiber connection speed be?

Typical fiber connections range from 100 Mbps to 1 Gbps for download speeds. Upload speeds are usually similar to download speeds on fiber networks.

Why test packet loss and latency?

Packet loss indicates network reliability issues, while latency (ping) affects real-time applications like gaming and video calls. Fiber should have very low values for both.
