“…As mentioned before, the most successful application of RoF technologies has been the transmission of wireless standards over optical fibre links in centralized architectures, also known as distributed antenna systems (DAS) for both indoor and outdoor applications. The broad bandwidth of the optical fibre facilitates standardindependent multiservice operation for cellular systems, such as GSM (Owaga et al, 1992), UMTS (Persson et al, 2006), wireless LAN (WiFi 802.11 a/b/g/n) (Chia et al, 2003;Niiho et al, 2004;Nkansah et al, 2006) and also for emerging technologies WiMAX (Pfrommer et al, 2006) and Ultra-wideband (UWB) (Llorente et al, 2007). Available commercial systems however are typically limited to frequency ranges between 800-2500 MHz.…”

“…Devices with bandwidth handling capabilities in excess of these required by near-term WIMAX deployments, in particular distributed feedback (DFB) lasers offering the required bandwidth and performances, exist commercially, but normally at a high cost taking into account the number of devices required for typical applications. Recently, a lot of research efforts have been devoted to the development of low-cost/high-performance transmitters, for instance uncooled lasers Hartmann et al, 2003) or vertical-cavity surface-emitting lasers (VCSEL) (Persson et al, 2006;Chia et al, 2003). Probably, the most restrictive requirement for wireless services provision over RoF systems is the SFDR.…”

“…The huge bandwidth of the optical fibre link and the availability of wireless commercial devices facilitate the standards-independent optical transmission and multiservice operation for existing cellular systems. Several transmissions of different wireless standards using radio-over-fibre techniques have been demonstrated so far, such as GSM [19], UMTS [20], wireless-LAN WiFi 802.11 a/b/g/n [21]- [23]), and WiMAX [24].…”

“…Recently, important research efforts have been carried out targeting the development of low-cost/high-performance transmitters, for instance uncooled lasers [36]- [37] or verticalcavity surface emitting lasers (VCSEL). In the last years, VCSELs have been proposed for low-cost direct modulation [20]- [21]. These VCSELs operate in a single longitudinal mode using of a very small cavity length (around 1 μm).…”

“…Existen dispositivos DFB comerciales con anchos de banda funcionales cercanos a 10 GHz, y de forma experimental, se ha conseguido hasta 37 GHz de ancho de banda en frecuencias ópticas de 1550 nm [Bac03]. Por otra parte, en sistemas RoF de bajo coste, se utiliza la tecnología láser de modulación directa VCSEL [Chi03], [Per06]. Esta tecnología se considera de bajo coste debido a sus reducidas dimensiones, puesto que se utilizan cavidades inferiores a 1 µm con buenas eficiencias de acoplo que permiten operar en una sola longitud de onda.…”

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...
