Available in PDF, EPUB and Kindle. Book excerpt: Long reach passive optical networks (PONs) are currently emerging as one of the leading candidates for the next generation of telecommunications access networks, which will provide end customers with future high bandwidth interactive and video-rich services. In order to satisfy future bandwidth demand in an economic fashion it is likely that PON technology will need to evolve dramatically from that which is commercially available today. In particular the reach of these networks will need to increase fivefold to around 100km and the supported data rates will jump by nearly an order of magnitude to around 10Gb/s. In this thesis a hybrid dense wavelength division multiplexed- time division multiple access passive optical network (DWDM-TDMA PON) suitable for use in next generation optical access networks is proposed and studied. In order to implement such challenging architectures new types of high speed, burst mode optical transmission techniques are required, which enable bandwidth sharing between users on the network. This project has developed these new burst mode techniques and sub-systems required to enable these new networks. The main aim of the investigations in this thesis are in overcoming all the physical layer challenges due to 10Gb/s burst mode nature of transmission in these types of networks. A range of investigations, both of a theoretical and experimental nature, such as the dynamics of optical amplifiers, interferometric noise mitigation, suppression of crosstalk from multiple sources, maximum transmission distance, etc., are carried out to optimise the performance of individual components as well as the fully integrated system. The suitability of hybrid DWDM-TDMA architectures as a cost effective solution for use in future optical access networks is verified through full-scale network demonstrations in an experimental long reach PON laboratory test-bed.

Download or read book Performance Analysis and Centralised Optical Processing in Next Generation Access Networks written by B. Cao and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Next Generation Passive Optical Network (NG-PON) is currently being standardised and developed, with a goal to achieve higher bandwidth at 10Gb/s, greater capacity at thousands of users and longer backhaul reach at 60km or 100km. The aim is to provide cost effective solutions for telecom operators to vastly deploy optical access networks, enabling customers with the benefit of the greater bandwidth and wider range of services. This thesis presents research that has identified and addressed various design issues relating to next generation access networks. Interferometric noise may be present in future, ring based, access networks which utilise WDM and OADMs. Simulation and experiment results are presented which studies the performance tolerance to not-precisely-defined wavelength, in the presence of interferometric noise. The impact of receiver electrical filtering was also investigated. The next generation access network will, in the upstream direction, use burst transmission and are likely to need a large tolerance to wavelength drift due to the low cost equipment used at the customer's premises. A demonstration of optical burst equalisation was presented, based on SOAs. This study also explores the possibility of reducing the SOA saturation induced non-linear distortions through simulations and experiments. As an extension to the optical burst equaliser and to remedy the saturation induced distortions, an intermediate site optical processing system was proposed. This solution not only performs burst-mode wavelength conversion at 10 Gb/s, but also pre-chirps the signal to allow long-reach transmission and suppressed level fluctuation to ease the requirements on the burst-mode receiver. As a result, a proof of concept 10Gb/s Wavelength Converting Optical Access Network (WCOAN) with up to 62km DWDM backhaul is experimentally demonstrate. It is designed to consolidate drifting wavelengths, generated with an uncooled laser in the upstream direction, into a stable wavelength channel for DWDM long backhaul transmission.

This book was released on 2008-07-16 with total page 224 pages. 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?

Download or read book Optical Burst mode Transmission for Metropolitan Area Networks written by Jaedon Kim and published by . This book was released on 2007 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metropolitan Area Networks (MANs) interconnecting high-speed backbone and low speed access networks mostly rely on IP Router and SONET/SDH Transport layer. Although SONET/SDH combined with WDM technology has increased transmission capacity, the efficiency issue regarding data transmission over a circuit switched network is still present. In addition, IP Router is not scalable solution in terms of cost, size and power requirement. Recently, access networks starts to provide a large amount of bandwidth by employing advanced LAN technologies, such as xDSL, cable modems, passive optical network (PON), and wireless access. Consequently, metro networks are expected to suffer a lack of bandwidth to support access network traffic in the near future. Although optical network solutions would solve such a metro gap problem, it is not simple for service providers to deploy a new optical MAN solution over a legacy MAN. While high bandwidth and reliable service are in users' interests, the reduction of OPEX and CAPEX is an important consideration to the service provider. Optical burst mode transmission allows different senders to transmit through the same channel, and saves network deployment cost. Besides their resource sharing features, burst mode transmission is feasible to data transmission, because it can achieve on time bandwidth provisioning for the network traffic having bursty nature. Furthermore, Burst mode transmission can provide scalability with optical bypassing capability. In this talk, the author proposes new metro network architecture using burst mode transmission technology. Its performance analysis and implementation issues in reality are discussed. The solution is verified using experimental testbed as well as simulation model.
