Energy consumption of telecommunication access networks

GPON GPON has a different network structure than Point-to- Point networks. It is based on a passive distribution network with optical splitters. The downstream signal from the PoP is passively separated into several subscriber signals by the splitter. The upstream signal is generated by merging the individual subscriber upstream signals. The location of the splitters can be very different. For example, they can be located somewhere in the field near to the subscriber, like the street cabinets in the copper twisted pair network, or they can be located directly at the PoP – a so called GPON over Point-to- Point structure. In this study the GPON over Point-to- Point structure is considered. This allows the same network structure as for the Point-to-Point network. This leads to two PoP sizes of 512 subscribers per PoP and 1,024 subscribers per PoP. To determine the number of PoPs, a georeferenced analysis of the individual municipalities is carried out. An attempt is made to keep the number of PoPs as low as possible. For this purpose, the respective municipal area is divided into quadrants so that the number of subscribers per PoP reaches as far as possible the maximum PoP size. The assignment of the customers to the respective quadrants begins in the densely populated inner cities and is then extended to the outer districts. 17
