Santa Rosa Internet provider is seeking approval to build a high-speed fiber network in San Francisco's Sunset District, it said Wednesday.

The pilot project would reach 2,000 homes in the neighborhood, paving the way for a larger San Francisco rollout.

Sonic now offers a similar full-Gigabit service in Sebastopol for $69.95 per month. The deal also includes phone service.

The San Francisco fiber project would begin next year if Sonic gets the permits, it said. Sonic now sells copper-based broadband and phone service throughout the Bay Area.

Sonic plans to reach most San Francisco homes with fiber over the next five years, the company said.

"There is a huge demand in San Francisco for higher bandwidth services, and fiber is the only long-term way to meet this demand," said Sonic CEO Dane Jasper.
