Abstract
The present invention is a fiber optic data network, such as a passive optical network (PON), which includes a primary sub-network and a secondary sub-network. The primary sub-network may include a primary optical line terminal communicatively coupled to a plurality of primary optical network units. The secondary sub-network may include a secondary optical line terminal communicatively coupled to a plurality of secondary optical network units and to an intermediate optical network unit. The secondary sub-network may be communicatively coupled to the primary sub-network via the intermediate optical network unit, thereby allowing the PON to be configured so that the primary optical line terminal and the secondary optical line terminal are cascaded.
