Telecom fiber net additions measure the net increase in fiber broadband connections during a reporting period under the carrier's stated scope.

It is a fiber-network customer-growth measure, not the number of locations passed by fiber.

Fiber adds show customer adoption of the wired network

AT&T reported 367,000 total consumer and business fiber net additions in the second quarter of 2026.

Verizon reported 155,000 fiber broadband net additions.

The metric helps investors connect capital-intensive fiber deployment with actual customer growth.

Additions are different from passings

A location can be passed by fiber without becoming a paying customer.

Fiber net additions measure connections gained, while fiber passings measure addressable network reach.

Acquisition scope can affect comparisons

AT&T's 2026 results include acquired mass-markets fiber operations in certain reported totals.

Investors should read acquisition footnotes before treating year-over-year growth as entirely organic.

Primary-source examples

Telecom fiber net additions are most useful as a fiber-network customer-growth measure. Pair them with locations passed, penetration, broadband revenue, capital spending, and fixed-wireless growth.

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.
