AT&T is staying committed to its wireline network in the face of two significant natural disasters by replacing beyond-repair copper wiring with fiber optics.

The phone company has recently notified the Federal Communications Commission its existing facilities in parts of California that were damaged by last year’s wildfires will be replaced by fiber optic infrastructure.

Fierce Telecom notes customers affected by the Nuns, Tubbs, Redwood and Sulphur fires will be served by a new optical fiber network in portions of Sonoma, Ukiah, Santa Rosa, and Lower Lake.

“The circuits will be transferred to fiber based NGDLC systems,” AT&T said in a FCC filing. “The transfer of these circuits does not compromise the capacity of the cabinets.”

In Florida, as a result of last September’s Hurricane Irma, AT&T will migrate its irreparably damaged copper wire network that strings throughout the Florida Keys to a new fiber to the home network.

AT&T’s decision to maintain its wired networks comes in contrast to Verizon’s 2013 attempt to scrap its copper facilities on Fire Island, N.Y. and certain New Jersey barrier islands left devastated by Superstorm Sandy. Verizon hoped to replace traditional landline service with a wireless alternative known as VoiceLink. A firestorm of protests over the service’s limitations, sound quality, and reliability forced Verizon to scrap the plan in New York and install its FiOS fiber-to-the-home network instead.
