Abstract
The present invention relates to modular optical devices compatible with legacy form factors, for example, SFF, SFP, and XFP form factors. A housing contains optical components including a lens block, a fabricated package, at least one lens pin, and a substrate. The lens block is configured to receive one or more lens pins. The fabricated package is mechanically coupled to the lens block and includes a light source and/or a light detector and a connector for coupling the fabricated package to the substrate. The at least one lens pin is mechanically coupled to the lens block for directing optical signals between the light source and/or light detector and external components. The substrate is mechanically coupled to the fabricated package and the housing and electrically connected to the light source and/or light detector such that substrate circuitry can electrically interoperate with the light source and/or light detector.
