Abstract
A fiber optic network includes a fiber distribution hub including at least one splitter and a termination field; a plurality of drop terminals optically connected to the fiber distribution hub by a plurality of distribution cables; and a distributed antenna system (DAS). The DAS includes a base station and a plurality of antenna nodes. The base station is optically connected to the fiber distribution hub and the antenna nodes are optically connected to the drop terminals. Example splitters include a passive optical power splitter and a passive optical wavelength splitter. Signals from a central office can be routed through the passive optical power splitter before being routed to subscriber locations optically connected to the drop terminals. Signals from the base station can be routed through the wavelength splitter before being routed to the antenna nodes.
