Abstract
The present disclosure is directed to a keyed optical component assembly that ensures that the same has a proper orientation when press-fit into or otherwise coupled to a complimentary opening of an optical subassembly housing. In an embodiment, the keyed optical component assembly includes a base portion defined by a first end and a second end disposed opposite the first end along a longitudinal axis. A first arcuate region extends from the first end towards the second end and transitions into a tapered region. A second arcuate region extends from the second end towards the first end and also transitions into the tapered region. Therefore, the tapered region extends between the first arcuate region and the second arcuate region, and generally tapers/narrows from the second arcuate region to the first arcuate region. The resulting shape of the base portion may generally be described as an asymmetric tear-drop shape.
