ABSTRACT:
A data access arrangement (DAA) that includes a substrate and an optically-active component disposed on the substrate. The component is encapsulated with a radiation-transmissive material to form an optical medium. The DAA also includes a layer of opaque material disposed around the substrate and the optically-active component so that the substrate and the component are sealed from the outside environment. A lead frame is attached to the substrate that extends through and beyond the opaque material layer to enable electrical contact with the substrate and the component.
