| English abstract | Passive optical networks (PONs) represent a promising solution for modern access telecommunication networks. These networks are able to meet the increasing demands on transmission rate for demanding multimedia services, while they can offer typical shared transmission speed of 1.25 or 2.5 Gbps. The major role in deploying optical distribution networks ODNs plays the maximum attenuable loss, which is caused mainly by passive optical splitters. This paper proposes an innovative application of passive optical networks with optimized bus topology especially for local backbone data networks. Due to using only passive components, it is necessary to optimize certain parameters, especially an overall attenuation balance. Considering the possibility of such optimization, the passive optical network with optimized bus topology provides several interesting opportunities for specific applications. This paper will present selected aspects of passive optical networks and splitters with asymmetric splitting ratio. The essential part is focused on the practical demonstration of their use to optimize the passive optical network with bus topology, which acts as a local backbone network for structured cabling systems, and for local data networks in large buildings |
