Abstract :
Demands that must be met if cable system network architectures in urban centers are to adequately meet the transmission requirements of the next decade and provide an infrastructure for new revenue-producing transmission services are addressed. An upgrade, using fiber-optic technology, to an initial architecture based on current coaxial technology, utilizing high-performance feedforward configured trunk-line amplifiers, multiple AM microwave links to distribution nodes (hubs), backup supertrunks, and other conventional approaches, is described. The architecture adopted is explained, focusing on hub deployment. The requisite very-high-capacity, high-reliability feeder design is discussed.<>
