Many architectural realizations of the HFC network successfully support the services ranging from broadcast video (analog and digital), through pay per view and video on demand, to telephony and high-speed data. However, the HFC network and its architectural implementations continuously evolve to fulfill the increasing demand for reliability, high quality, and sufficient capacity to provide a broad array of services to an increasing number of customers.

This paper presents an analysis of various architectural implementations of the HFC network. These implementations range from a traditional Fiber-to-the-Serving-Area approach, through fiber overlay for digital services, to fully-passive coaxial networks fed by dedicated fibers.
