Bay Area ISP Sonic has launched fiber-based 1 Gbps Internet service, dubbed Fusion Fiber, in the Sunset and Richmond Districts of San Francisco. The service is available for ordering or pre-ordering and costs $40 per month. It also includes home phone service.

Sonic has previously deployed gigabit services in the Bay Area communities of Brentwood and Sebastopol, plus area business parks in Santa Rosa, Petaluma and Windsor. Those deployments used FTTH technology from ADTRAN (NASDAQ:ADTN).
