Download or read book Next-Generation FTTH Passive Optical Networks written by Josep Prat. This book was released on 2008-07-16. Available in PDF, EPUB and Kindle. Book excerpt: Fibre-to-the-Home networks constitute a fundamental telecom segment with the required potential to match the huge capacity of transport networks with the new user communication demands. Huge investments in access network infrastructure are expected for the next decade, with many initiatives already launched around the globe recently, driven by the new broadband service demands and the necessity by operators to deploy a future-proof infrastructure in the field. Dense FTTH Passive Optical Networks (PONs) is a cost-efficient way to build fibre access, and international standards (G/E-PON) have been already launched, leading to new set of telecom products for mass deployment. However, these systems only make use of less than 1% of the optical bandwidth; thus, relevant research is taking place to maximize the capacity of these systems, with the latest opto-electronic technologies, demonstrating that the huge bandwidth available through the fibre access can be exploited in a cost-efficient and reliable manner. Next-Generation FTTH Passive Optical Networks gathers and analyzes the most relevant techniques developed recently on technologies for the next generation FTTH networks, trying to answer the question: what’s after G/E-PONs?

Book Synopsis Media Access Control and Resource Allocation by : Nirwan Ansari

Download or read book Media Access Control and Resource Allocation written by Nirwan Ansari. This book was released on 2013-01-17. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on various Passive optical networks (PONs) types, including currently deployed Ethernet PON (EPON) and Gigabit PON (GPON) as well as next generation WDM PON and OFDM PON. Also this book examines the integrated optical and wireless access networks. Concentrating on two issues in these networks: media access control (MAC) and resource allocation. These two problems can greatly affect performances of PONs such as network resource utilization and QoS of end users. Finally this book will discuss various solutions to address the MAC and resource allocation issues in various PON networks.

Book Synopsis Analysis of the Performances and Tolerances of the 2nd Generation Passive Optical Networks (NGPON2) for FTTH Systems by : Juan Camilo Velásquez Micolta

Download or read book Analysis of the Performances and Tolerances of the 2nd Generation Passive Optical Networks (NGPON2) for FTTH Systems written by Juan Camilo Velásquez Micolta. This book was released on 2014. Available in PDF, EPUB and Kindle. Book excerpt: [ENGLISH] In a Fiber to the Home (FTTH) system, the fiber is connected until the household users. A passive optical network (PON) is a particular type of FTTH networks that uses P2MP (point-to-multipoint fiber premises) in which unpowered optical splitters are used to share part of the infrastructure enable a single optical fiber to serve multiple premises. The evolution of PON systems across the years can be associated with the evolution in multiplexing technologies. In the first years with the use of TDM the achieved upstream and downstream aggregate bandwidth was in the order of 155 Mbit/s until 10 GBit/s in XG-PON standard. But with the implementation of WDM the capacities have been increased significantly until get bandwidths of 250 GBit/s and 500 GBit/s using ud-WDM with coherent detection. This new standards use advanced modulation and codification formats. This project will evaluate the new international standard ITU-T G.989 for next generation optical fiber access to the home (FTTH) network operating at 4x 10GBit/s, that uses time multiplexing and dense wavelength multiplexing (TWDM). The key commercial devices for its implementation will be identified and modelled. Next, the access network will be built in a computer simulator, different tests will be run, and the system will be optimized. Tasks: · Study of the state of art of optical access networks comparing different technologies, devices, and architectures. · Analysis of the new international standard ITU-T G.989 to review the optical spectrum management, devices and subsystems proposed. · Use of VPI simulator in order to build an access network architecture and realize different tests, linking it with · MATLAB to analyze the achieved results. · Optimization of the network built.

Book Synopsis Gigabit-capable Passive Optical Networks by : D. Hood

Download or read book Gigabit-capable Passive Optical Networks written by D. Hood. This book was released on 2012-04-10. Available in PDF, EPUB and Kindle. Book excerpt: Gigabit-capable passive optical networks (G-PON) have a large and increasing base of support among telecommunications operators around the world. Written by two of the experts in the field, this book explains G-PON in detail, both the original 2.5 Gb/s version and XG-PON, the 10 Gb/s second generation. The foundation established by this book is also invaluable in understanding NG2 (next-generation 2) G-PON, which is built upon a number of XG-PON systems on parallel wavelengths. As well as a history that clarifies the reasons for many of the existing features, the book looks at current and evolving technology and discusses some of the alternatives for future access networks.
