Abstract
The relatively recent push to deliver broadband services has led to deployment of various new access network architectures. Fiber-to-the-Premises (FTTP) brings fiber all the way to the customer premises to enable higher-bandwidth services. In most cases it is too costly to dedicate a fiber optic connection from each subscriber to an Optical Line Terminal at the central office, so one or two levels of concentration are implemented using splitters along the way. We describe FTTP access network models with one and two levels of concentration, and we describe optimization models for automated splitter location and customer assignment. The models automate decisions on the location, size, and number of splitter clusters, where the particular choice is driven by cost. By automating the design process, such optimization methods allow more thorough assessment of tradeoffs in less time.
