What is the difference between fibre and cable broadband?

The answer

Fibre carries data as pulses of light through thin glass strands, while cable broadband uses coaxial cable, the same family of wiring long used for television signals. Capacity on a cable segment is usually shared among the homes connected to it, so slowdowns can appear at busy hours, and upload is often lower than download. Fibre is generally good at holding a steady connection. Real behaviour depends on the provider and your location, so ask which connection type will be installed at your exact address.
