“…Power Budget up to 28 dB [14], [15]. The formula for power budget calculation [14], [16] is given by (1), where PB is the power budget, PT is the transmission power of the class B+, PSENS is the ONT sensitivity and LT the total loss for the building with the ID 11200121. This equation can also be used for class checking and disregarding safety margins [16].…”

“…The installation of optical fiber in the access network, to provide adequate bandwidth and quality of service for the different services, is an expensive process. While the consumer demand for bandwidth continues to grow, solutions for the development of access networks have been studied [1]. The Fiber-To-The x (FTTx) solution becomes the focus of Service Providers (SP) in the development of the network, aiming to bring the fiber as close as possible to customers and make the network compatible with future fiber optic technologies.…”

Fiber optic access networks have been considered a definitive solution to the constant need for increasingly higher bandwidths. For this reason, PON (Passive Optical Network) have grown enormously in the recent years, offering different solutions to the end customer, whether it is residential or business. However, the PON project is complex and a time-consuming process. This paper is focused on a tool design that, when combined with the schematic of the PON project, performs the survey of all equipment used in the projected cell. This tool provides also the attenuation calculations, as well as the techno-economic study of the network. Simulations were carried out to test the viability of the software, considering the network analysis in two cases: with one service provider using the network or with two service providers sharing it.

Communication Network Architectures Based on Ethernet Passive Optical Network for Offshore Wind Power Farms

et al. 2016

View full text Add to dashboard Cite

Nowadays, with large-scale offshore wind power farms (WPFs) becoming a reality, more efforts are needed to maintain a reliable communication network for WPF monitoring. Deployment topologies, redundancy, and network availability are the main items to enhance the communication reliability between wind turbines (WTs) and control centers. Traditional communication networks for monitoring and control (i.e., supervisory control and data acquisition (SCADA) systems) using switched gigabit Ethernet will not be sufficient for the huge amount of data passing through the network. In this paper, the optical power budget, optical path loss, reliability, and network cost of the proposed Ethernet Passive Optical Network (EPON)-based communication network for small-size offshore WPFs have been evaluated for five different network architectures. The proposed network model consists of an optical network unit device (ONU) deployed on the WT side for collecting data from different internal networks. All ONUs from different WTs are connected to a central optical line terminal (OLT), placed in the control center. There are no active electronic elements used between the ONUs and the OLT, which reduces the costs and complexity of maintenance and deployment. As fiber access networks without any protection are characterized by poor reliability, three different protection schemes have been configured, explained, and discussed. Considering the cost of network components, the total implementation expense of different architectures with, or without, protection have been calculated and compared. The proposed network model can significantly contribute to the communication network architecture for next generation WPFs.
