Abstract
An optical assembly includes a first lens positioned along a first axis and configured to focus light from a light source along the first axis, and a second lens positioned along the first axis and configured to focus light from the first lens onto an optical target. A third lens is positioned along a second axis and configured to approximately collimate light from a second light source along the second axis, and a reflector positioned along the second axis is configured to reflect light from the third lens onto a fourth lens. The fourth lens is positioned on a third axis angled from the second axis and configured to focus light from the reflector onto an optical detector. Furthermore, the optical assembly is preferably a single molded optic. The optical assembly may be used in an optoelectronic transceiver having an optical subassembly, including a light source and an optical detector. The optical assembly is used to couple a pair of closely spaced optical fibers to the light source and optical detector.
