OPTICAL CONNECTOR DEVICE

摘要

Provided is an optical connector device that exhibits high accuracy when positioning one lens relative to another lens (one ferrule and another ferrule) in the optical axis direction. The optical connector device is provided with: an emission-side ferrule (2) comprising, on the tip thereof, an emission-side lens (222) through which light that is emitted from an emission-side optical fiber (2f) passes; and an entry-side ferrule (3) comprising, on the tip thereof, an entry-side lens (322) that collects light that has passed through the emission-side lens (222) in an entry-side optical fiber (3f). At least one of the tips of the emission-side ferrule (2) and the entry-side ferrule (3) has formed thereon contact protrusions (223, 323) that are in contact with the other ferrule and that set the gap between the emission-side lens (222) and the entry-side lens (322) in the optical axis direction.
