Claim:
1. A fiber optic cable adapter assembly comprising: an adapter housing defining a first port, a second port, and a through-passage extending between the first port and the second port, the adapter housing configured to mount to an opening formed in a mounting wall of a pressurized enclosure such that the first port is open to an exterior of the enclosure to receive a first fiber optic connector from the exterior of the enclosure and the second port is arranged in the interior of the enclosure; an adapter module disposed within the through-passage and configured to couple the first fiber optic connector and a second fiber optic connector within the adapter housing, the second fiber optic connector being preassembled with the adapter module through the second port of the adapter housing before the adapter housing mounts to the opening of the mounting wall, the second fiber optic connector being fully received within the adapter housing; a mounting flange formed on the adapter housing and configured to abut one of an inner surface and an outer surface of the mounting wall of the pressurized enclosure when the adapter housing mounts to the opening of the mounting wall; a mounting nut engaging a portion of the adapter housing to sandwich the mounting wall of the pressurized enclosure between the mounting flange and the mounting nut; an enclosure seal element disposed around the opening of the mounting wall between the mounting flange and the mounting nut to seal the adapter housing around the opening of the enclosure; and a second port seal element disposed around a fiber optic cable of the second fiber optic connector at the second port to seal the adapter housing from the interior of the enclosure at the second port of the adapter housing, wherein the enclosure seal element and the second port seal element are configured to maintain a positive or negative pressure within the pressurized enclosure relative to atmospheric pressure.
