Design and Implementation of 200 G Passive Optical Network

The explosive growth of Internet has led to a demand for high bit rates for home and office users and the increasing popularity of video-related services means that even higher bit rates will be required in the near future.Time Domain Multiplexed (TDM) PONs are a cost-efficient solution for providing high bandwidth to users.Combined with Wavelength Division Multiplexing (WDM), very scalable and flexible network architectures are possible.The main disadvantage of TDM PONs is that, since users share the available bandwidth, the total system bit rate is the sum of the bit rate guaranteed to each user. The increasing demand for higher user bit rates mean that the system bit rate will need to be very high, requiring expensive electronics and optoelectronics at the Central office (CO) and the Optical Network Unit (ONU)

Passive Optical Networks (PON) can be a better solution for the networks accessed in the future, due to their property of high bandwidth availability and energy saving. PON is a point to multipoint mechanism and provides applications like data transmission and reception (IP), video and voice (triple play). For the support of symmetric, high-speed and perfect bandwidths for future services like high definition TV quality and traffic patterns that include video and image services other than voice and text, we require passive optical networks. This paper presents the architecture, PON technologies and detailed discussion on scope of various passive optical networks.

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.

In this paper, a central power source architecture is applied to a realize power saving wavelength division multiplexing passive optical network (WDM-PON). Parametric study isevaluated to extend the transmission distance up to 60 and80 km. Optical launched power is optimized through the parametric study. A full duplex 16 optical channels WDM-PON system are experimentally simulated and analyzed. Successful transmission achieved maximum bit error rate (BER) of 10-13 .A return-to-zero differential phase shift keying (RZ-DPSK) modulation technique isutilized for downlink direction, and then the downlink signal is re-modulated for the uplink direction using intensity modulation technique of on-off keying (OOK) with a data rates of 5 and 1 Gbit/s per channel.

A number of applications are growing day by day and so the traffic. The need for bandwidth is also increasing at a rapid rate. The bandwidth and speed with which data can be transferred was very less when compared to core networks. The access network which was once a bottleneck is no longer so because of use of optic fiber (FTTH networks). A number of variants of Passive Optical Network (PON) have been proposed like the WDM PON and the Hybrid PON. Hybrid PON is a combination of TDM PON and WDM PON and is advantageous over WDMPON. This paper focuses on high capacity networks that can provide high data rate and long reach in the access part of the network. NRZ modulation format is normally used for transmission. We consider the advantages provided by the advanced modulation formats like DPSK. This modulation format is used to here and its benefits are evaluated in Hybrid PON network to increase the capacity and the reach of the network. Parameters like the BER and the Q factors are a...

Due to the rapid growth of Internet with new generation of services and applications, demand for faster and cheaper access network has been rising. To address the present and future demand, broadband fiber access technologies such as passive optical networks (PONs) are a potential solution. Mostly, time division multiplexed (TDM)-PON is deployed in all parts of the world. In order to mitigate the future demand, some next-generation PON systems have been investigated by the researchers. In this paper, we examine the current status of PONs and investigate the probable future PONs. We also explain the smooth migration process from the current status to the future technologies. Architecture of a self-restored tree-type hybrid wavelength division multiplexed/TDM-PON (WDM/TDM-PON) has been proposed, for migrating from TDM to WDM-PON. Due to the restorable capacity of the architecture, the availability of the system is increased. In addition, cost analysis of different PON architectures are performed and compared with the cost of the proposed architecture. It is found that, the proposed architecture provides more cost effective solution.

This paper summarizes the research and technical achievements done under the EU project GigaWaM. The goal of this project was to develop a cost-effective solution that can meet the increasing bandwidth demands in access networks. The approach was to use a novel wavelength division multiplexing passive optical network (WDM-PON) architecture that can deliver symmetric 1 Gb/s to 64 users over 20 km standard single mode fiber using the L and C bands for down and upstream, respectively. During the course of the project, a number of key enabling technologies were developed including tunable transceivers, athermal 50 GHz spaced arrayed waveguide grating multiplexer devices, novel hybridization technologies for integration of passive and active electro-optic devices, and system-level algorithms that ensure the quality of service. The outcome of the project proved a reliable, cost-effective, flexible, and upgradable WDM-PON solution, achieving per-user datarates of 2.5 and 10 Gb/s for up and downstream, respectively. The proposed solution is not only suitable for access networks, but also for metro aggregation and mobile backhaul.

Building on the Ethernet Passive Optical Network (EPON) and Gigabit PON (GPON) standards, Next-Generation (NG) PONs ( ) provide increased data rates, split ratios, wavelengths counts, and fiber lengths, as well as ( ) allow for all-optical integration of access and metro networks. In this paper we provide a comprehensive probabilistic analysis of the capacity (maximum mean packet throughput) and packet delay of subnetworks that can be used to form NG-PONs. Our analysis can cover a wide range of NG-PONs through taking the minimum capacity of the subnetworks forming the NG-PON and weighing the packet delays of the subnetworks.
