The emerging fifth-generation mobile communications are envisaged to support massive number of deployment scenarios based on the respective use case requirements. The requirements can be efficiently attended with ultradense small-cell cloud radio access network (C-RAN) approach. However, the C-RAN architecture imposes stringent requirements on the transport networks. This book chapter presents high-capacity and low-latency optical wired and wireless networking solutions that are capable of attending to the network demands. Meanwhile, with optical communication evolutions, there has been advent of enhanced photonic integrated circuits (PICs). The PICs are capable of offering advantages such as lowpower consumption, high-mechanical stability, low footprint, small dimension, enhanced functionalities, and ease of complex system architectures. Consequently, we exploit the PICs capabilities in designing and developing the physical layer architecture of the second standard of the next-generation passive optical network (NG-PON2) system. Apart from being capable of alleviating the associated losses of the transceiver, the proposed architectures aid in increasing the system power budget. Moreover, its implementation can significantly help in reducing the opticalelectrical-optical conversions issue and the required number of optical connections, which are part of the main problems being faced in the miniaturization of network elements. Additionally, we present simulation results for the model validation.Keywords: 5G, backhaul, centralized unit (CU), common public radio interface (CPRI), distributed unit (DU), fiber to the X (FTTX), fronthaul, functional split, optical wireless communication (OWC), passive optical network (PON), photonic integrated circuits (PICs), radio access network (RAN), radio over fiber (RoF) 1 mobile devices and applications in the networks. This is in an effort to enhance the user experience in delivering enhanced mobile broadband (eMBB) services and providing ultra-reliable low-latency communication (uRLLC) for critical communication and control services. In theory, IoT comprises universal existence of a collection of things like mobile PCs, tablets, smartphones, actuators, sensors, wireless routers, as well as radio-frequency identification (RFID) tags. It is remarkable that these devices are capable of cooperating not only with each other but also with their neighbors. By this approach, they are able to achieve common network goals by means of unique addressing scheme [1,2]. Furthermore, it has been predicted that massive number of mobile devices on which various bandwidth-intensive applications and services will be operating and will be Internet connected [3]. In actual fact, there is a tremendous demand for effective systems that are capable of delivering various services in a cost-effective manner while meeting the essential network demands. Consequently, in an effort to accomplish the next-generation mobile network technical demands, there have been intensive researches on viable solutions th...

“…Figure 5 shows a proposed migration path from the current AON PtP to WDM-PON. The considered WDM-PON implementation [9][20] has 80 wavelength channels with space of 50 GHz, which is beyond the standardized WDM-PON option in NG-PON2 [8]. Cyclic Arrayed Waveguide Gratings (AWGs) are used at the CO to aggregate 80 distribution fibers into one feeder fiber which uplinks to the OLT at the MAN.…”

“…TWDM is a hybrid technology of WDM and TDM, which is also used by ITU-T [6] as a primary technology for NG-PON2. In this paper, the considered TWDM-PON implementation [9][20] has 40 wavelength channels, which is beyond the 4 or 8 wavelength channels defined in the current NG-PON2 standard [8]. In the considered migration case, the active RNs are replaced by passive power splitters (1:32), while the Ethernet switches at the old COs are replaced by 40-channel AWGs (see Fig.…”

Abstract-Active Optical Network (AON) has been one of the most deployed fiber access solutions in Europe.However, with the increasing traffic demand, the capacity of the existing AONs is becoming insufficient. For the legacy AONs, there are two major variants of architectures, namely point-to-point and active star.Considering the different characteristics of these two AON architectures, this paper proposes and analyzes several migration paths towards Next Generation Optical Access (NGOA) networks offering a minimum 300Mbit/s sustainable bit rate and 1Gbit/s peak bit rate to every end-customer. Furthermore, this paper provides detailed descriptions of the network cost modeling and the processes for AON migration. The Total Cost of Ownership (TCO) for the proposed migration paths are evaluated taking into account different migration starting times, customer penetration, node consolidation and business roles in the fiber access networks. The migration from AON to NGOA can be economically feasible. The results indicate that a network provider plays a key business role and is responsible for the major part of TCO for AON migration.Moreover, performing node consolidation during AON migration can be beneficial from the cost point of view, especially in rural areas.

Passive optical networks (PONs) are telecommunication networks that provide services to users by no active elements. Only passive elements are used in the network to transmit the information and signals between users as well as between users and the companies operating the telecommunication networks.PONhave evolved from their infancy as fine and economical ideas, toward a long‐term, reliable, and cost‐effective technical solutions for providing access to most users to high‐speed Internet by Fiber‐to‐the‐Home (and similar) solutions.PONare still evolving, providing the base of multiple standardized networks and in combination with different technologies are growing into metropolitan networks and extensions of mobile communications.Herein, we overview the state of the art of passive optical networks as well as their basic concepts. This work is divided into four sections: In Section 1, we give a summary of the main concepts of passive optical networks. Sections 2 and 3 introduce the most important features ofITU‐TRecommendations andIEEEStandards for passive access networks, respectively. Finally, Section 4 concludes the article with an overview on the future trends ofPONsfor access networks.
