“…Fiber-to-the-home (FTTH) is the future-proof technology offering ultra-high bandwidth and long reach. Two main types of fiber access network architectures have been developed and deployed, namely Active Optical Network (AON) [1], and Passive Optical Network (PON) [2]- [11], both with different variants. Due to increased dependency on electronic services all over society and the growing importance of reliable service delivery the network reliability issues are becoming very significant.…”

SUMMARYFiber access network architectures such as active optical networks (AONs) and passive optical networks (PONs) have been developed to support the growing bandwidth demand. Whereas particularly Swedish operators prefer AON, this may not be the case for operators in other countries. The choice depends on a combination of technical requirements, practical constraints, business models, and cost. Due to the increasing importance of reliable access to the network services, connection availability is becoming one of the most crucial issues for access networks, which should be reflected in the network owner's architecture decision. In many cases protection against failures is realized by adding backup resources. However, there is a trade off between the cost of protection and the level of service reliability since improving reliability performance by duplication of network resources (and capital expenditures CAPEX) may be too expensive. In this paper we present the evolution of fiber access networks and compare reliability performance in relation to investment and management cost for some representative cases. We consider both standard and novel architectures for deployment in both sparsely and densely populated areas. While some recent works focused on PON protection schemes with reduced CAPEX the current and future effort should be put on minimizing the operational expenditures (OPEX) during the access network lifetime. key words: optical fiber LAN, protection, reliability, capital expenditures (CAPEX), operational expenditures (OPEX), fiber-to-the-home (FTTH), passive optical network (PON), active optical network (AON)

“…En general, el desarrollo de las redes PtMP WDM-PON tiene como 22 Capítulo 2. Integración de transmisiones radio en redes ópticas de acceso principales ventajas: (i) mayor régimen binario disponible en cada ONT mediante una sola longitud de onda, (ii) aumento de la seguridad al utilizar enlaces WDM, (iii) balance de potencia más favorable, ya que sólo introduce 9-12 dB de perdidas por cada 16-32 usuarios servidos, y (iv) posibilidad de dar servicio a más usuarios por cada longitud de onda, cuestión intrínseca al superponer una red PON, teniendo redes de 1 x N x M usuarios [Shu08], siendo N el número de redes PON y M el número de usuarios de cada red PON.…”

IVPersonal Area Network). L'objectiu d'aquest estudi és obtenir màrges de seguretat per a garantir la interoperatibilitat d'ambdues tecnologies ràdio, els quals es poden aplicar en el futur desenvolupament de tècniques avançades de mitigació de la interferència com detecció i exclusió (DAA, Detect-and-Avoid), dins de futures aplicacions com les anomenades cognitive radio.Després, s'estudia la coexistència de MB-OFDM UWB i WiMAX IEEE 802.16e en xarxes òptiques d'accés basades en sistemes RoF. S'avaluen dos escenaris experimentals: en el primer, s'avalua un sistema RoF amb fibra multimode, i el segon, un sistema RoF amb fibra monomode. Els resultats permeten obtenir màrges de seguretat i abast màxim per al desplegament de sistemes RoF segons els tipus de fibra. Al mateix temps, es demostra i avalua experimentalment una nova tècnica de multiplexació per divisió en polarització de la transmissió òptica, per a millorar la coexistència en sistemes RoF.Finalment, aquesta Tesi Doctoral presenta l'estudi del modulador electro-òptic Mach-Zehnder, com a peça clau que limita el marge dinàmic de les transmissions als sistemes RoF. Al mateix temps, es proposa i avalua experimentalment una tècnica òptica de linealització del modulador Mach-Zehnder que millora el marge dinàmic del sistema RoF. V AbstractCurrent network and telecommunication systems are required to provide higher data rates in access networks to an increasing number of users. This fact is mainly due to the increase in the Internet traffic data, which is related with the higher demand of online videogames and software, the increased complexity in the content of web pages, the joint distribution of audio-visual and added-value online content, and the introduction of high-definition services and contents such as video on demand, as a result of a society increasingly more interconnected. In order to satisfy these higher data rates requirements, new techniques for the joint distribution of several wireless communication systems are proposed in this Thesis. The aim of these techniques is to facilitate the deployment of an integrated access network at the customer premises, enabling the integration of optical transmission over an optical access network and radio-frequency transmission in the same infrastructure.Two main wireless communication systems are considered in this Thesis, WiMAX (Worldwide Interoperability for Microwave Access) and UWB (Ultra-Wide Band) according to WiMedia Alliance recommendation. Comparing the bit rate and expected range, WiMAX and UWB are complementary radio technologies expected to coexist in a near future in integrated access networks. The optical access network considered in this Thesis can be regarded as a FTTH network (Fibre-to-the-Home). The wireless signals are natively transmitted over optical network, that is, without frequency upconversion and remodulation stages, over one or several optical carriers. This technology, which is known as Radio-over-Fibre (RoF), is well suited for integrated access networks.First, the requirements for...
