Broadband access network nowadays has obtained increasing attention among internet users. High bandwidth demands and the need on mobility of the network cause the network design and architectures to be part of the hot topics in the research area. Wireline optical and wireless networks are two different architectures of broadband access network which offer advantages over each other. High capacity optical network integrated with tetherless wireless network enables high-speed communications to mobile users at anytime and anywhere. This paper defines integrated optical wireless broadband access network, outlines the architectures of different network models, the features and key issues of the network.

: In the present scenario, increasing bandwidth demand and data-hungry applications require every network to be equipped with cloud services, as a huge amount of storages, processing power and miraculous speed available with it. Cloud integrated Wireless Optical Broadband Access Network (CIW) is one of the suitable choices to fulfil these requirements. CIW can be realized by deploying Cloud Components (CCs) or thin servers either at optical back-end or at wireless front-end of the (Wireless Optical Broadband Access Network) WOBAN. In the present work, we integrate cloud components at wireless front-end of the CIW. Integration of CCs at front-end offloads traffic associated with cloud services from wireless front-end and diverts it towards CCs, which results in a reduction in bandwidth usage of the wireless front-end of WOBAN. We introduce a novel approach known as cluster-based optimization of network components in CIW. The proposed algorithm eliminates redundant Optical Network Units (ONUs) and optimizes a number of CCs while ensuring network connectivity and cloud services to all users. Simulation results validate that the proposed algorithm offers suitable candidature to deploy cost-efficient CIW.

AbstractWavelength-division multiplexed-passive optical network (WDM-PON) is a revolutionary high-capacity and scalable broadband access network. This paper capitalizes on Laguerre–Gaussian (LG) modes to reduce modal dispersion and increase data capacity. A data rate of 25 Gbit/s is attained for a multimode fiber link by multiplexing five LG modes on five wavelengths centered at 1,550.12 nm for a distance up to 800 m.

Abstract In this paper, we have proposed and analyzed a novel cost-effective ultradense wavelength division multiplexed (UDWDM) passive optical network (PON) which uses phase modulation (PM) of the optical carriers in the optical line terminal (OLT) in order to achieve inherent noise immunity in the network. In the demodulation of the optical PM signal at the optical network unit (ONU), we have proposed to use a simple injection–locked Fabry–Perot (FP) laser diode (LD) for achieving PM to intensity modulation (IM) converter which is followed by a photodiode to recover the specific channel information. A detailed analysis of PM–IM conversion in an injection–locked FPLD has been carried out and the viability of the proposed scheme has been established. The proposed UDWDM–PON which is a broadband access network is cost-effective and long reach.

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.
