Examining The Future Evolution Of The Access Network (2013)

By Michael J. Emmendorfer and Tom Cloonan, ARRIS

The MSOs are facing a decade of unprecedented change, driven by competition and consumer demand, which will transform the cable network end-to-end. This paper will focus on the evolution of the cable access network through this decade and beyond. We will examine the evolution of Coax to the Home (CTTH) and Fiber to the Node (FTTN) networking technologies and architectures that will emerge this decade.

The MSOs are maximizing capacity and performance of their current networks.

However, MSOs are finding the improvements to operations can’t yield any more bits per second per hertz (b/s/Hz). This paper will examine the future evolution of the access network, to identify some of the problems and proposed solutions to maximize b/s/Hz and “widen the pipe” to increase the capacity of existing and future spectrum.
