The development of our work is based on the planning and sizing of the broadband access network through FTTH, which will meet the needs of subscribers through services such as triple play (Internet, high definition television, Voip ...) For this it is therefore to better plan the architecture for a good repair of network equipment. To overcome these problems we have focused our study on planning with the help of Google Earth software, which will facilitate us through its tools of tracing and mapping for the sizing of links and locations of equipment for the collection and delivery of services in high speed.
