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 Long Reach RSOA Based Passive Optical Networks written by Sourav Mondal and published by LAP Lambert Academic Publishing. This book was released on 2014-10-01 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present access services like video on demand, live streaming, online gaming etc. require enormous amount of bandwidth and traditional digital subscriber line technology fails to meet up this requirement. The next generation networks, in particular, hybrid WDM-TDM Long-Reach Passive Optical Networks provide the required bandwidth and reduce the operational expenditure. Laser sources used at the Optical Network Units increase the cost due the extra equipment required for stabilizing the operating wavelength. To overcome this, a centralized source is installed at the Optical Line Terminal and the signal is reflected and intensity-modulated at the ONU, by using a special optical device Reflective Semiconductor Amplifier (RSOA), thus making the end receiver unit "colourless." The analytical model for RSOA has been described in detailed in this book. The primary objective of this enitre work is to examine the feasibility of hybrid WDM-TDM LR-PON physical layer uplink setup consisting of reflective ONUs with due consideration to the BER performance in presence of realistic and non-ideal characteristics of optical and optoelectronic devices used in the setup.
Download or read book A Novel Multi band CO OFDM Based Long Reach Passive Optical Network Architecture written by Mohamed Ben Zeglam and published by . This book was released on 2017 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis investigates a new long-reach passive optical networks (LRPON) architecture based on multi-band coherent optical orthogonal frequency division multiplexing (CO-OFDM). The proposed CO-OFDM based LRPON system is characterized by a novel phase noise compensation mechanism aiming to deal with optical signal dispersion in long-range transmissions. By employing a dispersion compensating fiber (DCF) and local oscillator (LO) laser phase shifter for each end-to-end transmission between OLT and ONU, we will show the phase noise due to dispersion can be effectively mitigated. Simulation of the downlink traffic between one optical line terminal (OLT) and 12 optical network units (ONUs) is performed successfully at different fiber lengths, at the data rate of 10$Gbps$ per ONU. The required BER for the forward error correction (FEC) has been achieved for most ONUs, using a dispersion compensating fiber (DCF) and local oscillator (LO) laser phase shifter to compensate for the chromatic dispersion (CD) and the polarization mode dispersion (PMD), respectively.
