The World Is Flat Capacity Optimization in a Coaxial Network, Constrained by Total RF Power (2016)

By Karl Moerder PhD, Futurewei Technologies Inc. and Fred Harris PhD, San Diego State University

As data traffic continues to grow, the cable industry is reaching the point where downstream capacity in a coaxial network is completely limited by the total integrated RF output power available from a node or amplifier. MSOs today are faced with the problem of increasing the peak network capacity to meet marketing and customer demand. Pushing fiber deeper into the network is one solution, but it is expensive. Working with the existing coaxial network and efficiently utilizing the RF power for maximum capacity can be a cost effective alternative.
