The fiber lines running to your Tempe home or business are not being replaced or rebuilt.
The network behind them is being absorbed into AT&T's national fiber infrastructure under new ownership and a completely new service model.

Lumen Technologies operated its consumer fiber business across Arizona under two brand names.
Quantum Fiber in markets where infrastructure had been fully modernized to fiber optic technology. CenturyLink in areas still running older legacy DSL technology on copper phone lines that had not yet been converted.
Tempe fell primarily under the Quantum Fiber brand across established neighborhoods from the Mill Avenue corridor and Tempe Town Lake through the mid-city residential blocks along McClintock Drive and the Southern Avenue corridor.
The acquisition moves the entire Lumen consumer fiber operation in Maricopa County under AT&T's infrastructure, expansion planning, and customer service model. For Tempe customers this means a significantly larger national network backing the same fiber lines already running to your Tempe address.
Tempe, AZThe physical fiber optic lines serving your Tempe neighborhood do not change as part of this transition. What changes is the company operating and expanding them. AT&T Fiber replacing Quantum Tempe AZ means East Valley customers gain access to AT&T's national infrastructure investment and support resources that Lumen's standalone consumer operation could not match in the Maricopa County market.
Understanding what shifts during the transition helps Tempe households and businesses plan accordingly. Here is a clear breakdown of what changes and what stays the same.
Tempe, AZMonthly billing transfers from Quantum or Lumen to AT&T. Tempe customers receive direct communication from AT&T regarding their specific account migration timeline, updated billing portal access, and any changes to existing plan terms before the changeover reaches their Maricopa County address.
Technical support, outage reporting, and all service requests transfer to AT&T's support structure. Tempe customers who previously contacted Quantum or CenturyLink support will reach AT&T directly for every service need once the transition processes their specific account.
No new installation is required at your Tempe address to complete the transition. Your existing fiber connection continues operating throughout the account migration. There is no service gap and no technician visit needed simply to complete the billing and account transfer from Quantum to AT&T in Maricopa County.
Quantum Fiber plans Tempe Arizona topped out at 940 Mbps on their highest residential tier across most Maricopa County markets. AT&T Fiber introduces a broader plan structure with clearer pricing at each tier and stronger infrastructure investment backing the Tempe network going forward.
Tempe, AZAT&T Fiber delivers equal upload and download speeds on every residential tier just as Quantum did. That symmetry continues without interruption. Tempe customers transitioning from Quantum will find the same fundamental fiber performance characteristic they already rely on preserved across every AT&T Fiber plan tier from day one of the transition.
Quantum Fiber residential plans in Tempe ranged from 200 Mbps to 940 Mbps across available tiers. AT&T Fiber residential plans offer 300 Mbps, 500 Mbps, and 1,000 Mbps symmetrical speeds with straightforward pricing at each tier.
Tempe households previously on a Quantum 200 Mbps plan will find the AT&T 300 Mbps entry tier a natural step up. Customers on Quantum's 500 Mbps or 940 Mbps tiers will find directly matching or superior options within the AT&T Fiber plan structure at their specific Tempe address.
Tempe, AZDepending on the equipment currently installed at your Tempe address AT&T may replace your existing Quantum gateway with an AT&T compatible device as part of the transition process.
