(1) The document discusses moving beyond Moore's Law by leveraging photonic technologies to increase network capacity. (2) It describes a trial implementation of a mini fiber node (mFN) that uses wavelength division multiplexing and digital processing to segment an HFC network and quadruple capacity. (3) Looking ahead, the network architecture will transition to an all-IP platform utilizing a common infrastructure for both data and voice services.
