Abstract:
<p>A number of applications are growing day by day and so the traffic. The need for bandwidth is also increasing at a rapid rate. The bandwidth and speed with which data can be transferred was very less when compared to core networks. The access network which was once a bottleneck is no longer so because of use of optic fiber (FTTH networks). A number of variants of Passive Optical Network (PON) have been proposed like the WDM PON and the Hybrid PON. Hybrid PON is a combination of TDM PON and WDM PON and is advantageous over WDMPON. This paper focuses on high capacity networks that can provide high data rate and long reach in the access part of the network. NRZ modulation format is normally used for transmission. We consider the advantages provided by the advanced modulation formats like DPSK. This modulation format is used to here and its benefits are evaluated in Hybrid PON network to increase the capacity and the reach of the network. Parameters like the BER and the Q factors are analysed using Optisystem Software. Distortion and the phenomena of dispersion can limit the performance of such a system. Hence Dispersion compensation mechanisms like the Dispersion Compensation Fiber (DCF) are used in the system to transmit data over large distance.</p>

Abstract:
It is 21 years since the first passive optical network (PON) was standardized as an asynchronous transfer mode passive optical network (APON) with same optical distribution network scheme as we know in current networks. A lot of PON networks were standardized in the following years and became an important part of telecommunication. The general principles of these PON networks are described in many papers and books, but only a little information about used lasers is available. The aim of this tutorial is to describe lasers used in PON networks and principles of their operation. The paper describes the principles of single longitudinal mode (SLM), multi longitudinal mode (MLM), distributed-feedback (DFB), and Fabry–Pérot (FP) lasers. Furthermore, the lasers are compared by their usage in optical line termination (OLT) for passive optical networks. The second part of this tutorial deals with activation process of optical network unit. The described principle is the same for connection of a new customer or blackout scenario. The end unit is not able to communicate until reach the operational state; each state is defined with physical layer operation and administration and maintenance (PLOAM) messages sequence and their processing.

Abstract:
Abstract Optical fiber has the great advantages of capacity and reliability. That is why network providers started to deploy FTTx (Fiber-To-The-x) optical access using various PON (Passive Optical Network) architectures. The leading technology right now is Gigabit PON (GPON). However, with increasing amount of multimedia we need to further develop existing technologies to go on with these high demands. Fiber-To-The-Home (FTTH) using 10G-PON technology for broadband access application is effective solution for high speed networks with high capacity. In this paper, we look at the passive optical network in the city of Košice and based on the real network we created simulation model of downlink of 10G-PON based FTTH with triple-play service.

Abstract:
Recently, metropolitan and access communication networks have markedly developed by utilizing a variety of technologies. Their bearer communication infrastructures will be mostly exploiting the optical transmission medium where wavelength division multiplexing techniques will play an important role. This contribution discusses the symmetric sharing of common optical network resources in wavelength and time domains. Wavelength-Division Multiplexed Passive Optical Networks (WDM-PON) attract considerable attention regarding the next generation of optical metropolitan and access networks. The main purpose of this contribution is presented by the analysis of possible scheduling of wavelengths for our novel hybrid network topologies considered for WDM-PON networks. This contribution briefly deploys adequate Dynamic Wavelength Allocation (DWA) algorithms for selected WDM-PON network designs with the provision of traffic protection when only passive optical components in remote nodes are utilized. The main part of this study is focused on the use of wavelength scheduling methods for selected WDM-PON network designs. For evaluation of offline and online wavelength scheduling for novel hybrid network topologies, a simulation model realized in the Matlab programming environment allows to analyze interactions between various metropolitan and access parts in the Optical Distribution Network (ODN) related to advanced WDM-PON network designs. Finally, wavelength scheduling methods are compared from a viewpoint of utilization in advanced WDM-PON networks designs.

Abstract:
With growing number of applications and network traffic, optic fibers are extensively used in the access part of the network. Passive Optical Networks (PON) in particular, Ethernet PON (EPON) networks based on Time Division Multiple Access (TDMA) are more prominently used in many parts of the world. Though Wavelength Division Multiplexing (WDM) PON has its own advantages, considering the cost and utilisation of such networks in the access part makes it less useful. On the other hand, Hybrid PON network combines the advantages of both EPON and WDM PON Networks. The objective of this paper is to identify suitable electrical filters for a 16-channel Hybrid Passive Optical Network with a transmission rate of 10Gbps per channel, by analysing their performance in terms of Q factor and Bit Error Rate. Different filters like the Bessel filter, Gaussian filter, Raised Cosine Filter, Rectangular filter, Butterworth filter, Chebyshev Filter are compared and their performances are evaluated. DB Modulation format that provides a longer reach is used at the transmitter to evaluate the different scenarios and the simulation is carried out using Optisystem.

Abstract:
The evolution of broadband telecommunication technologies has enabled applications over networks, which, in turn, has enabled the emergence of novel network services and applications such as VoIP and video on demand in triggering demand for higher network bandwidth. Passive Optical Networking (PON) is suitable for eliminating bandwidth insufficiency, so national governments and communities are observing the emergence of Fiber-To-The-Home (FTTH) technologies. Ethernet-based Passive Optical Networks (EPON) and Gigabit-based PON (GPON) are two candidates for next-generation PON in bandwidth efficiency. To predict which is more suitable nationally, we define a foresight framework based on hybrid Multiple Criteria Decision Making (MCDM) methods for selecting the most suitable PON. The development of next-generation PON, including Ethernet PON (EPON) and Gigabit PON (GPON), is introduced and compared. Experts from industry and academia were invited to predict the most suitable next-generation PON for Japan and emerging economies such as Taiwan. Results showed that EPON is most suitable for Japan and GPON most suitable for Taiwan. Results for the technological foresight can serve as the basis for national telecommunication policy and business product definition.

Abstract:
The broadband access networks require suitable differential modulation techniques that can provide better performance in real-time fading channels. A heterogeneous optical access network adopting spectrally efficient DAPSK – Orthogonal Frequency Division Multiple (OFDMA) - Passive Optical Network (PON) is proposed and simulated. The performance of the proposed heterogeneous network is analyzed in terms of received Bit Error Rate (BER) and spectral efficiency. The results show that 64 DAPSK – OFDMA over the proposed architecture achieves a better spectral efficiency of about 1.062 bps/Hz than 64 QAM – OFDMA with less degradation in error performance.

Abstract:
Due to the increasing demands of individual users, Passive Optical Networks (PON) are a promising technology for future broadband access networks. Reliable access to network services is a very important feature, so the availability of the connection is becoming one of the most important requirements. Failure of the optical fiber occurring between the Optical Line Terminal (OLT) and the passive optical splitter can cause the services becoming unavailable for a large number of users, so it is necessary to prevent such an occurrence by providing backup resources – in this case a spare optical fiber. When constructing the spare path (protection fiber), it is important to keep in mind that, if possible, the working and the spare fiber should not be positioned within the same cable. Failure of the optical fiber between the passive splitter and the individual user also means a loss of service for that user. In that case, protection may be offered by adding spare fibers. The question is, however, whether such a solution is cost-effective, as it would lead to a significant cost increase in the construction of the access network. This paper presents the availability analysis conducted for different PON models.

Abstract:
Les réseaux optiques passifs (PON) semblent être la technologie gagnante et ultime du futur pour les "fibres jusqu'au domicile" ayant une haute capacité. L'écoute de contrôle de ce genre de système est nécessaire pour s'assurer un niveau de qualité de service prédéterminé pour chaque client. En outre, l'écoute de contrôle réduit considérablement les dépenses en capital et de fonctionnement (CAPEX et OPEX), tant pour le fournisseur du réseau que les clients. Alors que la capacité des PON est croissante, les gestionnaires de réseau ne disposent pas encore d'une technologie efficace et appropriée pour l'écoute de contrôle des réseaux de capacité aussi élevée. Une variété de solutions a été proposée. Toutes ces dernières solutions ne sont pas pratiques à cause de leur faible capacité (nombre de clients), d'une faible évolutivité, d'une grande complexité et des défis technologiques. Plus important encore, la technologie souhaitable pour l'écoute de contrôle devrait être rentable car le marché des PON est très sensible aux coûts. Dans cette thèse, nous considérons l'application de la technologie du codage optique passif (OC) comme une solution prometteuse pour l'écoute de contrôle centralisée d'un réseau optique ramifié tels que les réseaux PON. Dans la première étape, nous développons une expression pour le signal détecté par l'écoute de contrôle et étudions ses statistiques. Nous trouvons une nouvelle expression explicite pour le rapport signal utile/signal brouillé (SIR) comme outil de mesure métrique de performance. Nous considérons cinq distributions PON géographiques différentes et étudions leurs effets sur l'SIR pour l'écoute de contrôle d'OC. Dans la prochaine étape, nous généralisons notre modèle mathématique et ses expressions pour le contrôle des signaux détectés par un détecteur quadratique et des paramètres réalistes. Nous évaluons ensuite les performances théoriques de la technologie basée sur l'écoute de contrôle selon le rapport signal/bruit (SNR), le rapport signal/bruit plus coefficient d'interférence (SNIR), et la probabilité de fausse alarme. Nous élaborons l'effet de la puissance d'impulsion transmise, la taille du réseau et la cohérence de la source lumineuse sur le rendement des codes unidimensionnels (ID) et bidimensionnels (2D) de l'écoute de contrôle d'OC. Une conception optimale est également abordée. Enfin, nous appliquons les tests de Neyman-Pearson pour le récepteur de notre système d'écoute de contrôle et enquêtons sur la façon dont le codage et la taille du réseau affectent les dépenses de fonctionnement (OPEX) de notre système d'écoute de contrôle. Malgré le fait que les codes ID et 2D fournissent des performances acceptables, elles exigent des encodeurs avec un nombre élevé de composants optiques : ils sont encombrants, causent des pertes, et ils sont coûteux. Par conséquent, nous proposons un nouveau schéma de codage simple et plus approprié pour notre application de l'écoute de contrôle que nous appelons le codage périodique. Par simulation, nous évaluons l'efficacité de l'écoute de contrôle en terme de SNR pour un PON employant cette technologie. Ce système de codage est utilisé dans notre vérification expérimentale de l'écoute de contrôle d'OC. Nous étudions expérimentalement et par simulation, l'écoute de contrôle d'un PON utilisant la technologie de codage périodique. Nous discutons des problèmes de conception pour le codage périodique et les critères de détection optimale. Nous développons également un algorithme séquentiel pour le maximum de vraisemblance avec une complexité réduite. Nous menons des expériences pour valider notre algorithme de détection à l'aide de quatre encodeurs périodiques que nous avons conçus et fabriqués. Nous menons également des simulations de Monte-Carlo pour des distributions géographiques de PON réalistes, avec des clients situés au hasard. Nous étudions l'effet de la zone de couverture et la taille du réseau (nombre d'abonnés) sur l'efficacité de calcul de notre algorithme. Nous offrons une borne sur la probabilité pour un réseau donné d'entraîner l'algorithme vers un temps exorbitant de surveillance du réseau, c'est à dire le délai d'attente de probabilité. Enfin, nous soulignons l'importance du moyennage pour remédier aux restrictions budgétaires en puissance/perte dans notre système de surveillance afin de supporter de plus grandes tailles de réseaux et plus grandes portées de fibres. Ensuite, nous mettrons à niveau notre dispositif expérimental pour démontrer un m PON avec 16 clients. Nous utilisons un laser à modulation d'exploitation directement à 1 GHz pour générer les impulsions sonde. Les données mesurées par le dispositif expérimental est exploité par l'algorithme de MLSE à détecter et à localiser les clients. Trois déploiements PON différents sont réalisés. Nous démontrons une surveillance plus rigoureuse pour les réseaux ayant une répartition géographique à plusieurs niveaux. Nous étudions aussi le budget de la perte de notre dispositif de soutien plus élevés de capacités du réseau. Enfin, nous étudions le budget total admissible de la perte d'exploitation du système de surveillance dans la bande de fréquences à 1650 nm en fonction des spécifications de l'émetteur/récepteur. En particulier, la limite totale de la perte de budget est représentée en fonction du gain de l'amplicateure de transimpédance (TIA) et le résolution de la conversion analogique-numérique (ADC). Par ailleurs, nous enquêtons sur le compromis entre la distance portée et la capacité (taille de fractionnement au niveau du noeud distant) dans notre système de suivi.

As redes ópticas passivas de nova geração 2 (NG-PON2) estão estudando e considerando o WDM-PON (Wavelength-Division-Multiplexed Passive Optical Networks) como a nova arquitetura para as redes de acesso, é provável que esta arquitetura seja adotada num futuro como o padrão. No entanto, algumas instalações já foram realizadas em todo o mundo, a maior parte delas na Coréia do Sul. Com o objetivo de reduzir os custos de operação (OPEX) e garantir a qualidade do serviço (QoS) um sistema de supervisão e localização de falhas é necessário. Neste trabalho é proposto e demonstrado um OTDR sintonizável (Optical Time-Domain Reflectometer) para realizar o monitoramento de redes WDMPON em serviço. O método apresentado é provado para diferentes fontes laser sintonizáveis CW (Continuous Wave) e utiliza um amplificador óptico semicondutor (SOA) como comutador para o sinal de prova. O sistema de monitoramento é provado experimentalmente numa rede WDM-PON simulada no laboratório a qual utiliza um AWG (Arrayed Waveguide Grating) como distribuidor. Os resultados foram melhorados utilizando diferentes métodos para mitigar os efeitos de interferência.
The Next Generation Passive Optical Network 2 (NG-PON2) is considering and studying wavelength-division-multiplexed passive optical networks (WDM-PONs) as the new architecture for access networks, this architecture is likely to be adopted in near future as standard. However some deployments have been achieved worldwide, most of them in South Korea. In order to lower the operational expenditure (OPEX) and guarantee quality-of-service (QoS) an in-service monitoring and fault localization system is required. We propose and demonstrate a tunable optical time-domain reflectometer (T-OTDR) for in-service monitoring of (WDM-PONs). The proposed method is proved for different continuous wave tunable laser sources (CW TLS), and uses semiconductor optical amplifier (SOA) as a switch for the probe signal. This monitoring system is experimentally proved in a simulated WDMPON employing a cyclic AWG (Arrayed Waveguide Grating) as wavelength distributor. We improve the results using different methods to mitigate the interference effects.

Recentemente , as redes ópticas de nova geração têm sido motivo de acesa discussão nos meios científicos. Com o aumento verificado nos últimos anos do numero de utilizadores e o aparecimento de novos serviços disponibilizados através das redes de acesso, torna-se cada vez mais claro que a fibra óptica é a única solução para disponibilizar a largura de banda necessária. Neste trabalho é apresentado um novo método passivo capaz de aumentar os níveis de escalabilidade e reconfigurabilidade destas redes. O método consiste no controlo da quantidade de potência de bomba entregue a um amplificador ou conjunto de amplificadores remotos em série, permitindo o controlo independentemente do ganho fornecido por cada amplificador. Utilizando o método proposto consegue-se evitar o uso de componentes activos, ou mais complexos, para controlo da quantidade de potência de bomba a fornecer aos amplificadores remotos, tornando o processo de amplificação simultaneamente passivo e reconfigurável. Foi também desenvolvido, no âmbito deste trabalho, uma ferramenta de simulação baseada em algoritmos genéticos, capaz de simular e determinar a melhor solução para diversos cenários, optimizando os diversos parâmetros. Foi também realizada a caracterização de uma fibra óptica dopada com érbio, onde foi estudado o comportamento do ganho da fibra dopada quando bombeada por um sinal de bomba diferente dos comprimentos de onda nominais, 980nm e 1480nm. Ainda, o caso de bombeamentos com diferentes comprimentos de onda multiplexados foi motivo de estudo. ABSTRACT: Recently, the new generation optical networks are being the focus of several discussions in the scientific forums. With the observed increase of users in the last years, and the emergence of new services supplied through the access networks, it became even clearer that optical fiber is the best solution to provide the required bandwidth. In this work it is presented a new passive method capable to improve the scalability and reconfigurability of those networks. The method consist in controlling the amount of pump power to be supplied to one or various remotely pumped optical amplifiers disposed in series, and by this, adjust independently the gain of each. Using the proposed method, it is possible to dismiss the use of active or/and complex components, to control the remote amplifiers conditions, making all this amplification process passive and reconfigurable. It was also developed during this work, a simulation tool based in genetic algorithms, capable to simulate and reach the best solution for different network scenarios, optimizing the several parameters. A laboratory characterization of an erbium doped fiber amplifier it was also performed, where it was studied the gain behaviour of the doped fiber, when it is pumped by a signal which wavelength is different of the nominal wavelengths, 980nm and 1480nm. In this characterization it was also studied the gain behaviour when the amplifier is pumped with multiple multiplexed pump signals.

As redes ópticas passivas (PONs) prometem satisfazer os requisitos dos utilizadores e provedores de serviços de forma a obter débitos mais elevados, quando comparados com as tecnologias baseadas em cobre. Com este trabalho pretende-se estudar e apresentar as tecnologias PON correntes actualmente, as suas características principais e alguma interpretação de como estas conseguem satisfazer os requisitos impostos. Vários standards para PON têm vindo a ser desenvolvidos ao longo dos anos e, considerando que a necessidade de melhores características de serviço é contínua, surgiram as redes ópticas passivas de próxima geração. As NG-PONs prometem satisfazer as exigências dos novos serviços, garantindo melhor qualidade de serviço global que os seus antecessores. Neste trabalho as recomendações do ITU-T e do IEEE são estudadas e apresentadas em detalhe e, como corolário, são comparadas por forma a identificar as suas diferenças e semelhanças. Com base nos conhecimentos obtidos, e com o intuito de validar por simulação alguns dos limites impostos pelas normas são feitas várias simulações de uma rede PON, seguindo a norma 10G-EPON. São variados parâmetros como distância da fibra, número máximo de utilizadores e perdas máximas por inserção de forma a poder avaliar o seu efeito e enquadrar com a norma obtida.
Passive Optical networks (PONs) promise to overcome the requirements of users and service providers to achieve higher data rates than conventional cooper Technologies. This work study and present the actual PON technologies, their main features and how they can successfully fulfill the imposed requirements. Several PON recommendations have appeared all over the years and due to ever increasing demand of improved services, PON networks evolved to Next Generation Passive Optical Networks. NG-PONs come to respond to the new quality and demanding services, ensuring better global performance than their antecessors. The ITU-T and IEEE recommendations are studied and presented in detail, and by corollary are compared in order to easily comprehend the differences and similarities between them. Based on the knowledge obtained and with the aim of validate by simulation some of the boundaries imposed by the recommendations, several simulations of a PON network are performed, following the 10G-EPON standard. Parameters like, fiber distance, number of users and maximum insertion loss are changed to evaluate their impact in the PON performance and to frame them in the recommendation.

By adopting a ring topology and optical switches we propose a novel protection mechanism for time division multiplexed passive optical network (TDM-PON) that provides resilience against multiple network fails. Some protection schemes have been proposed in order to give resilience for passive optical network (PON) as defined at ITU-T Recommendation G983.1. However that recommendation defines the optical distribution network (ODN) and equipment duplication to protect it against multiple points of fail. We propose a ring topology with dual fibers paths capable to protect the network by switching these lines individually according to the local alarms detected by each optical network unit (ONU). According to our proposal neither equipment nor network should be duplicated to provide survivability to the system.

Muitos esquemas de proteção foram propostos para dar confiabilidade para as redes ópticas passivas como definido pela recomendação ITUT G.983.1. Para permitir proteção contra múltiplos pontos de falhas a recomendação ITU-T define a duplicação da rede óptica (ODN) e equipamento. Apresentamos, então, uma topologia em anel com dois caminhos ópticos distintos protegendo a rede pela comutação individual destas linhas de acordo com a detecção de alarmes locais por cada Optical Network Unit (ONU). Conforme nossa proposta, nem o equipamento ou a rede precisam ser duplicadas para prover proteção do sistema.

The bandwidth-intensive applications, such as interactive video and multimedia services, have further increased the demand of bandwidth. Thus wavelength division multiplexing passive optical network (WDM-PON) is viewed as a promising candidate to realize the next generation optical access networks due to its dedicated bandwidth for each subscriber and more flexible bandwidth management. The first half of this thesis will cover three technologies in a WDM-PON, including multicast overlay scheme, automatic protection switching scheme and tunable Fabry-Pérot laser diode (FP-LD) self-seeding scheme. In the second half of the thesis, WDM optical network is utilized as a virtual computing environment, which connects widely distributed computing resources to support large-scale scientific, engineering or commercial computing applications. It is so called "optical Grid" systems. Grid applications may range from the simple transfer of a large data set to the complex execution of a collection of interdependent tasks. However, for such a system involving many heterogeneous computing and network resources, faults seem to be inevitable. This thesis will also address the issue of maximizing grid application availability in real-time optical Grid systems through resource-fault-tolerant scheduling techniques.

Abstract:
Wavelength division multiplexing passive optical network (WDM-PON) can meet growing bandwidth demand in access network by providing high bandwidth to the end users. Failure in the access network is becoming critical as a large volume of traffic might be affected. Therefore, an effective supervision mechanism to detect and localize the fault is required to shorten the service interruption time. Meanwhile, open access provides a certain freedom for end users to choose the service and hence boosts competition among service/network providers. On the other hand, to offer open access in WDM-PON could result in a substantial change on architectural design, e.g., multiple feeder fibers (FFs) instead of a single one may be required to connect different service/network providers. Consequently, the traditional supervision mechanisms don’t work properly in open WDM-PON. To fill in this gap, several fault supervision mechanisms to support open access in WDMPON are proposed in this thesis. They can be applied to both disjoint and co-located FF layout where the choice of providers is done through wavelength selection. The feasibility of such solutions has been validated by evaluating transmission performance. We have carried out simulations in VPItransmissionMaker for different deployment scenarios. The results have confirmed that no significant degradation of the transmission performance is introduced by the proposed monitoring schemes compared to the benchmark, where no any fault supervision method is implemented.

Abstract:
This book presents an in-depth deliberation on optical networks in four parts, capturing the past, present, and ensuing developments in the field. Part I has two chapters presenting an overview of optical networks and the enabling technologies. Part II has three chapters dealing with the single-wavelength optical networks: optical LANs/MANs, optical access networks using passive optical network architecture, SONET/SDH, optical transport network and resilient packet ring. Part III consists of four chapters on WDM-based optical networks, including WDM-based local/metropolitan networks (LANs/MANs) using single and multihop architectures over passive-star couplers, WDM/TWDM access networks as an extension of PONs with WDM transmission, WDM metro ring networks covering circuit-switched (using point-to-point WDM and wavelength-routed transmission) plus packet-switched architectures and WDM long-haul backbone networks presenting the offline and online design methodologies using wavelength-routed transmission. Part IV deals with some selected topics in six chapters. The first deals with transmission impairments and power-consumption issues in optical networks, while the next three chapters deal with the survivable optical networks, network control and management techniques, including GMPLS, ASON, and SDN/SDON, and datacenter networks using electrical, optical, and hybrid switching techniques. The final two chapters present elastic optical networks using flexible grid for better utilization of the optical-fiber spectrum and optical packet and burst-switched networks. The three appendices present the basics of the linear programming techniques, noise processes encountered in the optical communication systems, and the fundamentals of queuing theory and its applications in telecommunication networks.

Abstract:
In this paper, the passive optical network (PON) evolution trend has been discussed. The literature of PON standards which are ATM PON (APON), Broadband PON (BPON), Gigabit PON (GPON), 10-Gigabit-capable passive optical networks (XG-PON) and next-generation PON2 (NG-PON2) has been reviewed extensively. From the literature review, a comparison of the PON technologies is made. The GPON, XG-PON and NG-PON2 are the most recent PON generations, and these are simulated to find the split per wavelength supported. The Q-factor below 6 is considered unacceptable in the analysis. The results show that the GPON can support 32 ONU when transmitted power set to 3dB. In the case of XG-PON, the Q-factor remains more than 6 for a split ratio up to 16. For the NG-PON2, the observed Q-factor is more than 6 for split up to 32. However, as the split increases above 32, the Q-factor falls below the acceptable level of 6.
