Analysis of Dispersion Compensation System for PON using Different Schemes
Abstract: In this paper, dispersion compensation techniques are discussed for better communication. Different schemes like pre-compensation, post- compensation and symmetrical compensation of DCF with NRZ and Manchester modulation format. To compensate the dispersion of fiber, DCF is used. Simulations have been analysed by using OptiSystem 7.0 simulator. Results are compared in terms of BER, Q-factor and total received power.Keywords: Dispersion Compensation, Dispersion Compensation Fiber (DCF), Passive Optical Network (PON), Q-factor, BER.Cite …

Past, Present and Future of Passive Optical Network
Abstract: ABSTRACTDemand for faster and cheaper access network has been rising due to the rapid growth of Internet with new generation of services and applications. Optical fiber has been envisioned for delivering broadband services for more than 30 years and becomes almost essential recently. To address the present and future bandwidth demand, broadband fiber access technologies such as Passive Optical Networks (PONs) are a potential solution. Mostly, Time Division Multiplexing (TDM) …

Performance of NRZ and Manchester DPSK Downstream and Upstream OOK for WDM-PON
Abstract: AbstractA novel data re-modulation scheme with downstream. Differential phase shift keying (DPSK) signals and on-off keying (OOK) upstream signal modulation format is proposed for wavelength-division multiplexing (WDM) – passive optical networks (PON) in the letter. A simulation on 5-Gb/s downstream optical DPSK signal and 5 Gb/s upstream optical OOK signal. 5Gb/S on DPSK OOK all are successfully demonstrated over 20-km single mode fiber without chromatic dispersion compensation.Keywords: Differential phase-shift keying …

ONU Placement and Restoration using Ant Colony Optimization Algorithm for Fiber Wireless Network
Abstract: AbstractFusion of optical domain and wireless domain makes a new promising technology called as Fiber Wireless (FiWi) access network, which actually integrates the features of both in it. FiWi consists of passive optical network (PON) as optical backend which serves high bandwidth, high data rates etc. and wireless mesh network (WMN) as wireless frontend which provides the self-healing nature, high mobility and low cost. Various optimizing schemes for Optical Network …
