SOFTWERSKI ALAT ZA PROCJENU ODRŽIVOG RAZVOJA FTTH PRISTUPNIH MREŽA
SOFTWARE TOOL FOR ASSESSMENT OF FTTH ACCESS NETWORKS

Summary/Abstract: In the paper is presented developed software tool intended for assessment of Fibre To The Home (FTTH) next generation optical access networks. The software tool CABE is based on mathematical models that comprise aspects of network Cost, Availability, Bandwidth and Energy. The models include specific requirements for analysis of access networks in urban, suburban and rural areas. Subscribers prediction is based on Gompretz model. The tool provides the following analyses: total cost of the network, the cost per subscriber, revenue, the payback period, sensitivity to cost changes of network elements, prediction of the power consumption and level of availability. In order to verify the tool, selected case studies of access network are assessed and compared: GPON, P2P and WDM. The results of analyses are presented in numerical and graphical form. By changing input parameters any specific local condition of FTTH access network can be taken in to account and assessment carried out.
