Does anyone have some simple project about Optical Access network based on PON? I need any project documentation on any topic related to PON, in OPNET, Matlab, or any other program. Please help. tnx

Optical access network
Optical access network.doc (Size: 452.5 KB / Downloads: 31) Introduction: The idea of using optical fiber to connect equipment at the customer premises to carries facilities has existed for at least a couple of decades. For the concept to become a reality, several enabling factors had to be addressed, including the following: • The availability of affordable multiplexing equipment • The deployment of fiber cables in sufficient quantity to create a critical mass for service offerings • The readiness of service providers to offer services In addition, a market had to be developed to make use of the optical fiber bandwidth capacity. Need for optical Access: Demand, ever-improving technology, and deregulation are significantly disrupting the telecommunications marketplace, presenting service providers with tremendous opportunities as well as precipitating huge changes in network alliances. The existing infrastructure has not kept pace with the exponential network growth new business applications such as e-commerce high-quality videoconferencing, telemedicine, large-file transfers, data mirroring, carrier hotels, and data-storage warehousing all are driving the need for ultrahigh bandwidth services. New species of service providers, such as Internet service exchanges (ISXs), application service providers (ASPs), and storage service providers (SSPs) are emerging, experiencing rapid growth in their businesses and scrambling for market-share. How Optical Access Fulfills the Need: Optical access platforms are designed to help new carriers leverage the current telecom market disruption for their own success. The market structure rewards products and solutions that have the inherent power to push optical networks beyond the domain of carriers backbones, providing fiber access for last-mile services-the crucial missing high-performance link in data networks. . Technology Workings: One of the challenges to be faced when structuring an optical access network is the very broad spectrum of potential applications and the multiplicity of solutions being developed to meet its needs. Various network topologies can be successfully used to meet the needs. Various network topologies can be successfully used to meet the needs of high-speed networking: hub and spoke, multi drop, ring, and mesh. The possibility of intermixing access network technologies within the network further complicates the situation. In the end, the performance and suitability of any combination of network configuration and technology depends on the bandwidth and scalability required as well as the nature of the current network, including any legacy systems, economic factors, and future expansion plans. Access Topologies and Applications: Various network topologies are used to meet the needs of high-speed traffic in the access network: hub and spoke, multidrop, ring, and mesh. In hub-and-spoke networks, data can be aggregated and sent point to point using either single-channel or multichannel techniques. Each method and its characteristics are presented here. |
