Google has been expanding the service, which promises Internet speeds of up to 1,000 megabits per second, in several cities in the United States.
"If there is a surprise here, it is perhaps that the growth rate isn't higher," MoffettNathanson said.
"After all, there has been a steady stream of new cities announced, and they've now been at it for a long time in at least a handful of markets."
The service is currently available in Atlanta, Austin, Charlotte, Kansas City, Nashville, Salt Lake City, San Antonio Provo, Utah, and Raleigh-Durham, North Carolina, according to the Google Fiber website.
Alphabet, formerly Google, said in December it would consider bringing the Fiber internet service to Los Angeles and Chicago.
