Abstract: The invention pertains to an optical interface employing optics (e.g., lenses) that image the beams rather than collimate the beams. More specifically, each connector at an interface includes optics, e.g., a lens, adapted to receive a diverging beam emanating from field point and image the beam to an image point at a predetermined distance from the imaging lens. A connector employing such optics may, for instance, be effectively mated to either a similar connector with the same optics or to a connector having no lens. Specifically, it may effectively be mated to a second connector having no lens via a second connector structure that places the receiving optical component at the image point of the focusing optics of the first connector. Alternately, such a connector may be effectively mated to a second connector having an identical lens to the first connector provided that the first and second connector structures are adapted to mate such that the image points of the two lenses are coincident.
