At present Optical fibre cable is used as media to design long/short network and it supports high bandwidth in Gigabits per second speed. Earlier OFC is used to connect the long distance places and called Optical transport network and presently used even in local/ Access network called Optical Access network. In present environment data to be transmitted is so high due to growth in internet. Successful transmission of such a huge bandwidth is big challenging job for long distance network designer. This paper aims to explain the design and planning of a Passive Optical Network (PON) based wireless fibre to the Home architecture. The purpose is to show the behaviour of links of optical fibre when the signal goes through all the elements such as optical fibre, splitters, multiplexers and the goal is to find a good quality of signal in all receivers. The final goal pursued with this paper is to evaluate the performance of the whole system. The steady increase in the demand for broadband services and the consequent increase in the volume of generated traffic in our communication networks have motivated the need to implement next generation access networks in our territories. To develop multimedia telecommunication networks as an infrastructure, it is necessary to install highly reliable optical fibre cable network architecture like PON based fibre to the Home Network. In a point-to-multipoint architecture, PON is an appropriate architecture to provide high bandwidth for many customers. For any Internet Service Providers, the biggest challenge is to design an efficient access network like PON to ensure the QoS and maintenance of that network that includes Identification and Rectification of cable faults in that access network within short time thus enabling efficiency and reputation of ISPs. So this work deals with design and & S. Mary Praveena

“…Some researches have focused on next-generation passive optical networks (NG-PONs), which aim to achieve higher bandwidth in optical networks. But the cost of deploying NG-PONs is very high due to the fact that existing optical network units (ONUs) and optical line terminals (OLTs) are not directly compatible with the technical requirements of NG-PONs [5], so ONUs and OLTs must be replaced or upgraded to support NG-PONs, which is a costly method at present. At the same time, there have been growing recent researches towards data caching as an approach for alleviating bandwidth pressure in fiber networks.…”

Fiber-Wireless (FiWi) access networks have been widely deployed due to the complementary advantages of high-capacity fiber backhaul and ubiquitous wireless front end. To meet the increasing demands for bandwidth-hungry applications, access points (APs) are densely deployed and new wireless network standards have been published for higher data rates. Hence, fiber backhaul in FiWi access networks is still facing the incoming bandwidth capacity crunch. In this paper, we involve caches in FiWi access networks to cope with fiber backhaul bottleneck and enhance the network throughput. On the other hand, power consumption is an important issue in wireless access networks. As both power budget in wireless access networks and bandwidth of fiber backhaul are constrained, it is challenging to properly leverage power for caching and that for wireless transmission to achieve optimal system performance. To address this challenge, we formulate the downlink wireless access throughput maximization problem by joint consideration of power allocation and caching strategy in FiWi access networks. To solve the problem, firstly, we propose a volume adjustable backhaul-constrained waterfilling method (VABWF) to derive the expression of optimal wireless transmission power allocation. Then, we reformulate the problem as a multiple-choice knapsack problem (MCKP) and propose a dynamic programming algorithm to find the optimal solution of the MCKP problem. Simulation results show that the proposed algorithm significantly outperforms existing algorithms in terms of system throughput under different FiWi access network scenarios.

“…The development of passive optical network (PON) systems has resulted in two families of standards being written by various groups [1][2][3][4][5]. The ITU-T PON systems are defined primarily in ITU-T recommendations, which cover the system, physical medium dependent (PMD), transmission convergence (TC), and management layers.…”
