Aprius, a Sunnyvale start-up that remains secretive, has raised an undiclosed amount of money from Lightspeed Capital Partners and New Enterprise Associates.

VentureBeat has heard it is working on an optical communications technology.

Chief executive Marc Verdiell said he isn’t ready to reveal any details. Verdiell founded Lightlogic, a company that provided 10 Gb/s Ethernet optical transceivers, which was bought by Intel in 2001.

Christophe Schaepe, of LightSpeed, and Forest Baskett, of NEA led the investment are on the board.
