An ONU design for EPON-based access network

Abstract: Ethernet passive optical network (EPON) is an emerging access network technology that provides a low-cost method of deploying optical access lines between a carrier's central office (CO) and a customer site The EPON can provide more bandwidth than xDSLs which are most widely deployed broadband solutions In this paper, we propose a cost effective structure of optical network unit (ONU) for EPON The proposed ONU is suitable for apartment that is a typical residential model in Korea The ONU system can process layer 2 functions such as VLAN, bandwidth management, priority control, etc In addition to these layer 2 functions, other services, such as L2 IGMP snooping, can be deployed easily

Free space optical wireless network

Abstract: This talk explore an over the air optical wireless network and to create a network architecture for reliable high data rate free space optical networks that can interoperate with traditional wired and fiber networks. These networks will have significant impact for applications between ships, airborne vehicles, satellites and land-based cloud computing and data centres as an integrated high speed information system. Throughputs of well over Tbps can be supported by the network, which is compatible with next generations of Ethernet at 100 Gbps. The big challenge is to engineer the free space optical wireless network in the presence of atmospheric turbulence and weather, so it will behave properly when interfaced to other wire-line networks and for the protocols of the various network layers to interoperate end-to-end in a heterogeneous network setting.

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

Abstract: 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.

Protection scheme for passive optical networks shared between a fixed and a mobile operator

Abstract: A protection scheme for passive optical networks (PONs) is proposed. It supports partial protection, relevant when reusing existing PON infrastructure for LTE-Advanced mobile network backhaul. We provide a protection level and cost analysis.
