Quantum Fiber Internet Speeds
Quantum Fiber leverages fiber-optic internet technology, which uses thin strands of fiber inside of a glass tube to send data at the speed of light from point to point. Because the data bounces back and forth at ultra-fast speeds, consumers who use Quantum Fiber will experience symmetrical download and upload speeds up to 8 Gbps. Unlike cable internet or DSL networks, where connections can slow down during peak times, Quantum Fiber delivers a seamless and consistent experience no matter what time of day you’re online.
