1. An optical assembly comprising:
a base comprising a body defining a base mating feature surface having a plurality of mounting posts, each having one or more conductive traces disposed on a portion of the mounting post; and
a plurality of optical modules arranged in side-by-side relation on the base and in optical communication with each other;
each optical module comprising a housing being commonly-shaped and commonly-sized with other housings, and each housing having a bottom wall defining a module mating feature surface comprising a plurality of openings, each coupled with respective mounting posts of the base mating feature surface, a plurality of sidewalls, each having at least one optical communication opening therein, at least one of the optical communication openings in the sidewall being aligned with an optical communication opening of an adjacent housing, and a top wall defining sides and a top wall mating feature surface comprising a plurality of conductive posts configured to be coupled with openings in the bottom wall of another stacked optical module, and cut-outs on each side of the top wall, each cut-out having a conductive trace formed thereon;
a respective optical device within each housing being aligned with a corresponding optical communication opening for direct optical communication with at least one optical device of an adjacent optical module; and
at least one conductive trace formed at each opening of each optical module and connected to a conductive trace disposed on a respective coupled mounting post and extending upward inside the housing to connect to a conductive trace on a respective cut-out of the top wall, and a wire bond connected between the respective optical device within the housing and at least one conductive trace inside the housing.
