Battery reserve sizing for fibre-in-the-loop equipment based on AC outage data

Telstra Corporation is currently deploying fibre-in-the-loop (FITL) facilities in Australia for pay-TV, and the potential future requirements of video-on-demand and multimedia services. FITL equipment located at the curb or customer's premises is expected to be powered from a local AC line connection, and hence it will be subject to AC outages. This paper discusses the use of typical metropolitan outage data recorded by Australian electricity supply utilities to assist in the optimum design of curb located FITL equipment. A FITL powering availability model is used to determine the power outage contribution to unavailability for a given battery reserve time.<<ETX>>
