Nokia-owned Infinera buys its San Jose tech site, solidifying presence

SAN JOSE — Nokia-owned Infinera has bought its San Jose site in a deal that solidifies 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 Road in south San Jose, according to documents filed on Feb. 18 with the Santa Clara County Recorder’s Office.

Nokia and Infinera created a plant at that 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 tech companies have estimated that the manufacturing effort would produce up to 200 tech jobs at that site.

Beverly Hills-based real estate firm Kennedy Wilson, acting through an affiliate, sold the building to Infinera through an all-cash deal, the county property files show.

The building totals 82,100 square feet, according to the Property Shark commercial real estate database. It was constructed in 2002.

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 in February 2025, paying $2.3 billion for the tech company. As a result of the deal, Infinera joined the Nokia optical networks business.

Nokia believes the deal has created an “innovation powerhouse” that will be 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.”
