Abstract: Technologies for expanded beam optical connectors are disclosed. In an illustrative embodiment, a lens array attached to a substrate includes several lenses aligned to optical fibers positioned in grooves in the substrate. The lens array also includes optical fiducials, such as opaque optical fiducials. Auxiliary optical fibers are aligned to the optical fiducials. Light can be sent through the auxiliary optical fibers and onto the optical fiducials, and a pattern of light can be detected after the optical fiducials. The pattern of light can be used to determine a position and/or orientation error of the lens array. The error can be used as feedback in several possible ways, such as repositioning the lens array, positioning a guide pin to match the position and direction of beams through the lenses, or adjusting a parameter of a manufacturing process.
