Book Description
The desire for high bandwidth multi-media reach content and the exponential growth of Internet traffic has led to the penetration of optical technologies into the access segment in the form of Fibre-To-The-x (FFT-x) topologies. Due to its cost effectiveness and low energy consumption, most FFT-x models have been based on Passive Optical Networks (PONs) where the employment of in-line active components has been discouraged. Next generation optical access networks are required to provide higher bandwidth-distance product and support wireless services in a cost effective manner. Through experimental and simulation work, this thesis examines the use of multicarrier modulation formats such as Orthogonal Frequency Division multiplexing (OFDM) and Filter Bank Multi Carrier (FBMC) as mans of helping to meet the bandwidth-distance requirements set for next generation optical access networks. OFDM and FBMC both exhibit high spectral efficiency and a tolerance to chromatic dispersion making them excellent candidates for use in next generation optical access networks. In order to promote cost efficiency these systems are also studied in conjunction with Direct Modulation of novel laser devices and direct detection. In this work, the accommodation of Long Term Evolution (LTE) services in hybrid wired/wireless optical access networks is also demonstrated using spectral notching either by deactivation of subcarriers in OFDM or line-coding techniques in OOK based wired services. The use of FBMC and OFDM is also studied in light of uplink transmission in optical access networks without the employment of spectral guard bands that is commonly used for the reduction of Multiple Access Interference (MAI).

Book Description
A cost effective, robust, and high capacity access network necessitated to meet the mounting customer demands for bandwidth-desirous services. A remarkable evolution of access networks is observed both in wired and wireless, predominantly driven by ever-changing bandwidth requirements. A wireless connection releases the end user from the restrictions of a physical link to a network that results in mobility, flexibleness, and ease of use. Whereas, optical networks offer immense amount of bandwidth that appease the most bandwidth voracious customers compared to bandwidth limited wireless networks. The integration of wired and wireless domains in the access landscape that presents a technical analysis of optical architectures suitable to support radio over fiber (RoF) is the objective of this chapter. Investigate the main trends that drive the merger of fiber and wireless technologies in access networks. Moreover, study the primary terms and the particular transmission features of integrated fiber-radio links to form a well-defined classification of hybrid systems and techniques. This work also recognizes the major problems for realization of RoF systems and examines the limitation, advantages, and diversity of integrated RoF-PON technology.

Book Description
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?

Book Description
A passive optical network (PON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 32-128. A PON consists of an optical line terminal (OLT) at the service provider's central office and a number of optical network units (ONUs) near end users. A PON configuration reduces the amount of fiber and central office equipment required compared with point to point architectures. A passive optical network is a form of fiber-optic access network.

Book Description
This handbook provides comprehensive knowledge on device and system technologies for seamlessly integrated networks of various types of transmission media such as optical fibers and millimeter and THz waves to offer super high-speed data link service everywhere. The seamless integration of the knowledge of radio and optical technologies is needed to construct wired and wireless seamless networks. High-frequency bands such as millimeter-wave and THz-wave bands where super wideband spectra are available can offer high-speed data transmission and high-resolution sensing. However, the expected coverage is limited due to large wave propagation loss. Thus, convergence of radio and optical links is indispensable to construct worldwide networks. The radio and optical technologies share the same physics and are closely related to each other but have been developed independently. Therefore, there is a big gap between these two fields. Bridging the two fields, this handbook is also intended as a common platform to design integrated networks consisting of wireless and wired links. Full coverage of wireless and wired convergence fields ranging from basics of device and transmission media to applications allows the reader to efficiently access all the important references in this single handbook. Further, it also showcases state-of-the-art technology and cases of its use.
