Abstract
An apparatus includes a cage structure and a cooling plate configured to contain a cooling liquid to cool the cage structure. The cage structure has a front end, a top surface adjacent to the front end, a first opening at the front end, and a second opening on the top surface. The first opening is configured to receive a pluggable optical module. The cooling plate is disposed on top of the second opening of the cage structure. The apparatus may further include a deformable pad disposed at the second opening of the cage structure and beneath the cooling plate.
