A package for housing a device includes a Faraday cage. The invention recognizes that the processing of signals associated with different types of communication standards can be recharacterized as deterministic data flows. The attachment lens comprises a cemented lens having a negative refractive power as a whole, the cemented lens including a first lens with a convex surface on an object side having a positive refractive power and a second lens with a convex surface on an image plane having a negative refractive power, and a third single lens having a positive refractive power. The suspension assembly includes a plurality of suspension pads on a suspension mounting surface. Further, the apparatus is effective to substantially isolate the secondary terminal blocks from temperature and pressure effects resulting from an arcing fault occurring in the enclosure.
