SAN JOSE — Nokia-owned Infinera bought its South San Jose site in a deal that cements the presence of the two companies in Silicon Valley.
Infinera, a maker of optical chips, paid just under $27 million for a large office and research building at 6373 San Ignacio Ave., according to documents filed Feb. 18 with the Santa Clara County Recorder’s Office.

Nokia and Infinera created a plant at the site for the manufacturing of optical chips. The production hub is on the ground floor of an existing two-story office and research building.
The companies estimated the manufacturing effort would produce up to 200 jobs.
Beverly Hills-based real estate firm Kennedy Wilson, acting through an affiliate, sold the building to Infinera through an all-cash deal, county property files show.
Constructed in 2002, the building totals 82,100 square feet, according to Property Shark.
In 2019, Infinera decided to shift its headquarters to the 6373 San Ignacio site, moving the head offices out of Sunnyvale in the process.
Finland-based Nokia bought Infinera for $2.3 billion in February 2025. As a result, Infinera joined the Nokia optical networks business.
Nokia claimed the deal created an “innovation powerhouse” that was able to capitalize on opportunities in the emerging artificial intelligence field.
“This transaction will significantly improve our scale and profitability in optical networks,” Pekka Lundmark, Nokia’s chief executive officer, said at the time of the acquisition of Infinera. “It allows us to speed up the pace of innovation to meet the requirements of the AI era.”
