Influence of uplink limitation and broadcast traffic on power efficiency in long-reach optical access network

摘要

Different optical access technologies are studied with respect to their power efficiency. Considered networks provide long-reach optical access. A network model that includes various network and energy related parameters has been developed. The influence of uplink capacity limitation and the amount of broadcast downstream traffic on power efficiency is evaluated within the developed network model. Long-reach passive optical networks provide the best power efficiency.
