Telecom fiber connections measure period-end customer connections receiving fiber broadband service under the carrier's reporting definition.

They are an installed fiber-customer base measure, not fiber locations passed and not quarterly fiber net additions.

AT&T reported 12.868 million total fiber internet connections at June 30, 2026. Verizon reported 10.913 million fiber broadband connections.

Connections differ from network reach

A carrier can pass many homes or businesses with fiber without converting all of them into paying connections.

That distinction is important when evaluating penetration and the return on network construction.

Net additions explain base growth

Fiber net additions show the number of customer connections added net of disconnects during a period. The ending connection count shows the cumulative installed base.

Acquisitions can also expand the base. Verizon's 2026 fiber totals include the impact of Frontier, while AT&T's 2026 results include acquired Lumen mass-market fiber assets.

Primary sources

Telecom fiber connections are most useful as an installed fiber-customer base measure. Read them with fiber net additions, locations passed, penetration, acquisition effects, and broadband revenue.

Part of the Telecom Wireless & Broadband Operating Model

Connect postpaid phone scale, growth, churn, broadband net additions, installed fiber and fixed-wireless bases, and prepaid phone scale, growth, and churn to understand telecom customer-base economics.

How the model fits together
  • Postpaid phone base, growth, and retention: Postpaid phone subscribers show the recurring phone base, net additions show whether it is expanding or contracting, and postpaid phone churn shows the rate at which customers leave. Issuer definitions remain specific to each carrier's retail population.
  • Broadband growth and access mix: Broadband net additions show total high-speed connectivity growth, while fiber and fixed-wireless net additions decompose the access technologies driving that growth. AT&T and Verizon use related but not identical internet and broadband labels.
  • Installed broadband base and prepaid dynamics: Broadband, fiber, and fixed-wireless connections show the installed access base behind net additions. Prepaid phone subscribers, net additions, and churn add a distinct lower-commitment wireless customer layer whose acquisition and retention economics differ from postpaid.
