Simulation and Performance Analysis of Passive Optical Networks (PONs)
The International Conference on Electrical Engineering, 2014
This paper aims to explain the design and planning of a passive optical networks (PON) which can build a fictitious environment allowing to study fiber to the home (FTTH) networks in depth and decide the optimal option for this environment. We design a network architecture based on FTTH systems with different bit rates (1.25 GB/s, 2 GB/s, 2.5Gb/s,5Gb/s and 10 GB/s). This architecture is targeted to deliver a very high speed data using optical communication between the edge nodes connecting the end users. This transmission allows the simultaneous delivery of triple play service (data, voice and video). In our design various data rates are studied. It has been observed that the proposed system is one of the most suitable methods concerning data rate. It is demonstrated that as we increase the data rate, the number of accommodated user's decreases due to high bit error rate. Also by increasing the distance of transmission, the system will be undesirable due to increasing the bit error rate.

SIMULATION AND PERFORMANCE EVALUATION OF PASSIVE OPTICAL NETWORK SYSTEM
PON provides virtually unlimited bandwidth to the users. It do not use electrically powered components to split the signal. Instead the signal is distributed using beam splitters. Each splitter typically splits a fiber into 16, 32, or 64 fibers, 55 km. BPON uses ATM as the protocol. The Broadband passive optical network (BPON) was the first attempt towards a PON standard. It is controlled by the ITU-T and is designated as ITU-T G.983. This paper provides an overview of PON and analyses network architecture, and evaluate the system performance in terms of BER and Q Factor of the PON system. The performance of PON System is evaluated using Opti system version 12.0.
The next generation of passive optical networks: A review
Journal of Network and Computer Applications, 2016
Passive O Q3 ptical Net Q4 works (PONs) have become a popular fiber access network solution because of its service transparency, cost effectiveness, energy savings, and higher security over other access networks. PON utilizes passive low-power components which removes the need for power-feeding in the fiber distribution network. This paper presents three different generations of PON that are based on the Ethernet PON and Gigabit PON standards. This article showcases the first generation of PON in terms of physical and data link layers and forms the basis for discussion about the different approaches being pursued for the next generation stage 1 PON (NG-PON1). Additionally, the main objective of this study is to review the technologies proposed for the next generation stage 2 PON (NG-PON2); highlighting the important contributions and limitations of the corresponding technologies. Hybrid approaches that combine multiple technologies are introduced as a solution to eliminate major limitations and to improve overall system-wise performance. However, NG-PON2 is still suffering from a number of challenges include cost, reach, capacity and power consumption are discussed at the end of this paper. Another purpose of this paper is to identify potential remedies that can be investigated in the future to improve the performance of the NG-PON2.
Passive Optical Access Networks: State of the Art and Future Evolution
Photonics, 2014
In the very last years, optical access networks are growing very rapidly, from both the network operators and the research interests points of view. Fiber To The Home (FTTH) is already a reality in plenty of real contexts and there has been a further stimulus to the proposal of new solutions and the investigation of new possibilities, in order to optimize network performance and reduce capital and operational expenditure. A complete and systematic overview of passive optical access networks is presented in this paper, concerning both the hot research topics and the main operative issues about the design guidelines and the deployment of Passive Optical Networks (PON) architectures, nowadays the most commonly implemented approach to realize optical fiber links in the access networks. A comparison of advantages and disadvantages of different multiplexing techniques is discussed, with specific reference to WDM-based networks, almost universally considered as the enabling technology for future proof bandwidth requirements. An exhaustive summary is also given about the-state-of-the-art of modulation and encoding techniques recently proposed by the scientific community, as well as the open challenges (such as colorless and coolerless ONUs) for telecom companies and international standardization compliance.
Passive-Optical-Network- (PON-) Based Converged Access Network [Invited]
Journal of Optical Communications and Networking, 2012
This paper describes an evolution of passive optical network (PON) technology deployment, which has primarily focused on residential markets, with triple play services consisting of voice, data and video, towards the support of a high value Ethernet and optical business services, with a vision of having a converged PON-based access network for all residential and business services. Business services, including wireless backhaul, are key components of a service provider portfolio, and use of the PON centric access network allows for more optimized deployment of these services. The paper also presents architectural approaches for supporting various types of business services over a PON-based fiber-to-the-premises network.
Design and Implementation of Gigabit Passive Optical Network
International Journal for Research in Applied Science and Engineering Technology IJRASET, 2020
The steady increase in the digitisation of every field created a desperate demand for broadband services and the consequent increase in the volume of generated traffic in our communication networks have motivated the need to make access networks in our rural territories too. This paper aims to explain the design and implementation of a passive optical network. The main idea of this paper is to build an optical fiber based access network for broadband connectivity to the rural areas. This will allow us to implement this network modal for expansion of reach of high speed broadband services in future.

INTRODUCTION The optical fiber is the most advanced transmission medium and the only one capable of supporting next generation networks and services. The main advantages of having a last mile of optical fiber are many: greater speed, higher bandwidth, and longer distance from the central to the subscriber, resistance to electromagnetic interference, higher security, and reduced signal attenuation. Moreover, the fact of using PON technology assumes the elimination of active components outside the plant such as repeaters and optical amplifiers and therefore decreasing the initial investment, reducing power consumption, lesser points of failure. Passive optical network (PON) access network is a point-to-multipoint, fiber to the home network architecture in which unpowered optical splitters are used to make a single optical fiber to serve multiple customers, typically 32-128 [1]. PON networks exploit the low attenuation of optical fiber cable (0.2-0.4 dB/km) and high bandwidth (>30,000 GHz) of single mode optical fibers [2]. These capabilities of PON give commonly more data transmission than as of now accessible networks with existing broadband advances. Also, PON based FTTH networks can give different communication services viz. voice, information and video from one platform [3]. Due to these advantages now most of the telecom operators use FTTH network as optical fiber access network. For a GPON based network maximum of 128 ONTs (Optical Network Terminal) can be included with maximum reachability of 60 km and maximum distance between two consecutive ONTs (Differential fiber distance) of 20 km as per G.984.6 ITU-T specification [4]. GPON uses data transmission speed of 2.44 Gbps in downstream and 1.24 Gbps in upstream. Broadcasting or continuous transmission for downstream and TDM technique for upstream are used as transmission method. In this paper, the approval of proposed design of network is done on the bas is of Link loss Budget and cost. The results shows that the continuity of newly laid optical fiber cable from OLT to ONTs and received power levels falls within optical power loss plan and the cost is lowest. This paper organized with different sections like Basic Components of GPON access network, design and Implementation with flowchart, results, and finally with the conclusion.
