A connection module includes a module body and a module circuit board arrangement. The module body defines a first port and an open first end providing access to the first port. The module circuit board arrangement extends across the open first end within a peripheral boundary defined by the module body. The module circuit board arrangement includes at least a first contact set that extends into the first port of the module body; an electronic controller that is electrically connected to the first contact set; and a circuit board connector facing outwardly from the module board arrangement. Example connection modules include optical adapters and electrical jacks.
