Why the Quantum Fiber to AT&T Fiber Transition Is Happening in Portland, Oregon

Lumen Technologies operated its consumer fiber business across the Pacific Northwest 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.

Portland fell primarily under the Quantum Fiber brand across established neighborhoods from the Pearl District and Hawthorne through NE Portland and the residential corridors extending toward Sellwood and the Gresham border.

The acquisition moves the entire Lumen consumer fiber operation in Multnomah County under AT&T's infrastructure, expansion planning, and customer service model going forward. For Portland customers this means a significantly larger national network backing the same fiber lines already running to your address.

Same Fiber Lines. A Much Larger Network Behind Them.

The physical fiber optic lines serving your Portland neighborhood do not change as part of this transition. What changes is the company operating and expanding them. AT&T Fiber replacing Quantum Portland OR means Portland customers gain access to AT&T's national infrastructure investment and support resources that Lumen's standalone consumer operation could not match in the Multnomah County market.
