Comcast says it has completed its fiber network expansion in Covington, an east metro Atlanta exurb that for years has been a TV production powerhouse of such shows as “In the Heat of the Night” and “Vampire Diaries.”

The Philadelphia-based cable giant said Monday it has installed a 10-mile fiber network that will offer businesses, schools, hospitals and government organizations Internet speeds of up to 10 gigabits per second.

“Comcast’s investment in Covington reflects this city’s impressive commercial and residential growth in recent years,” Comcast Regional SVP Jason Gumbs said in a statement. “Today’s announcement marks an important milestone for Covington, as it further establishes itself as an ideal destination for businesses seeking the most advanced technology available.”

Comcast has been rolling out fiber across metro Atlanta over the past five years to meet consumer demand for more broadband services for streaming TV, connected homes and ever-powerful cell phones and tablets.
