Abstract
An optoelectronic device for immersion in a liquid coolant includes a printed circuit board assembly (PCBA) having opposing sides and having an optoelectronic component coupled on one side. A lens block mounted to the side of the PCBA encloses a plenum over the optoelectronic component. An opening defined in the lens block forms a reflective surface. The lens block has a first lens facing the optoelectronic component and opposing the reflective surface. The lens block also has a second lens facing a ferrule, which connects to optical fibers and couples to the lens block. A first seal seals the lens block mounted to the PCBA and separates the plenum from the liquid coolant. An insert is disposed in the opening to protect the reflective surface, and a second seal seals the opening and the insert in the lens block. A third seal seals the ferrule to the lens block.
