Internet powered by fiber uses cutting-edge, 100% fiber technology. Fiber technology utilizes light waves instead of electrical signals to transmit data, and fiber optic cable can send higher volumes of information over longer distances than copper cable. This means customers on a fiber network have higher speeds available to them, regardless of their distance from a network node. AT&T FIBER® delivers 25x faster upload speeds than cable¹, making it great for gaming online. It's consistently fast, even at peak times².
