What Is Fiber Internet and How to Get It

Fiber optic internet is widely seen as the best home internet you can get today. Traditional cable and DSL send data through copper wire. 5G home internet and satellite send it through radio waves. Fiber uses pulses of light through thin glass or plastic cables instead. Light travels extremely fast and carries huge amounts of data, which is why fiber reaches speeds copper cannot match.

The biggest difference you will notice: fiber gives you symmetric speeds, meaning your upload speed equals your download speed. Cable internet might give you 300 Mbps download but only 10-20 Mbps upload. With fiber, a 1 Gigabit plan gives you 1,000 Mbps both ways. Fast upload speed matters for video calls, uploading photos or videos to the cloud, working from home, or backing up files online.

Fiber is also usually more reliable than cable, with fewer outages and steadier speeds at busy times. That is because fiber has far more capacity than copper, so speeds stay consistent even when many neighbors are online at once.

The main catch is availability. Cable reaches most American homes, but fiber reaches only about 50% of US households as of 2025 — though that number keeps growing. The biggest national providers are AT&T Fiber, Google Fiber (in select cities), Frontier Fiber, and Ziply Fiber (Pacific Northwest). Many areas also have local or regional fiber providers. If a fiber cable is not already at your house, a technician needs to run one — a one-time job.

If fiber is available at your address, it is generally worth switching from cable, especially if you can get it at a similar or lower price. Many fiber plans offer better speeds and reliability than cable at the same or lower monthly cost, particularly after cable providers' promotional rates expire.
