The present invention provides a transceiver housing comprising: an opening at a proximal end thereof for receiving a optical receptacle; an electrical contact for engaging the optical receptacle and retaining the optical receptacle in the housing body; and a first side and a second side, each of the first side and the second side including mountings for mounting a printed wire assembly within the housing. In a preferred embodiment, the transceiver housing of the present invention has a uni-body construction. The present invention also provides transceiver cage comprising: a hollow cage body made of metal for mounting a transceiver within the transceiver cage and for preventing radiation from outside the cage body from entering the cage body and for preventing radiation from the transceiver from exiting the cage body; a plurality of mounting pins extending from the cage body for mounting the transceiver on a printed wiring board; and a plurality of internal contact fingers at a proximal open end of the hollow cage body for engaging a chassis through which the transceiver cage is inserted. In a preferred embodiment, the transceiver cage of the present invention includes a latch release mechanism for holding a transceiver in the transceiver cage and a hinged access door for providing access to a connector mounted within the transceiver cage. In addition, the present invention provides a transceiver system including a transceiver cage having radiation control openings with a longest dimension no greater than 1/4 of the wavelength of the electromagnetic radiation corresponding to ten times the highest signal frequency present in the transceiver cavity.
