Abstract: A fiber distribution hub includes a set of carrier-specific and modular service provider housings in a scalable, stacked arrangement. Each service provider housing is associated with a dedicated carrier. The multiple service provider housing modules are individually selectively-integrated with one another to create a vertically-stacked distribution housing of the hub. The distribution housing functions as a common network resource shared by all of the service provider housings. In this shared distribution configuration, all of the service provider housings have access to the same distribution network servicing a subscriber population.
