Quantum Fiber is the fiber-optic internet service brand operated by Lumen (the same company behind CenturyLink’s legacy services). It delivers a “fiber to the premises” connection — meaning the fiber optic line extends all the way to your home or business wherever possible.
It is being rolled out gradually in markets formerly served by CenturyLink’s fiber infrastructure, with an aim to phase out older branding and bring long-term expansion.
Upload and download speeds are equal — useful for content creation, video conferencing, and cloud backups.
Quantum offers gigabit and even multi-gigabit speeds (in some areas up to 8 Gbps).
The network is designed to deliver 99.9% uptime and consistent performance.
No data caps or overage charges — true unlimited internet.
Month-to-month flexibility with no forced annual commitments.
Whole-home mesh WiFi system with the latest technology to reduce dead zones and boost coverage.
Easy online setup, ordering, and account management.
Quantum Fiber is available in hundreds of U.S. markets and is expanding rapidly. The network serves tens of millions of people across more than 500 cities. Availability and speed options depend on your ZIP code or address.
