Fiber vs cable: what changes in real use

Fiber gives symmetric upload, very stable latency and near-immunity to electrical noise. Cable shares capacity per neighbourhood segment, so evening congestion is common.

If you upload video, run backups or work over VPN, symmetric fiber usually feels dramatically better even at a lower advertised speed.

Run tests at several times of day to see congestion patterns. Your saved history in SpeedExact makes that comparison easy.
