Quadrature Amplitude Modulation All Optical Orthogonal Frequency Division Multiplexing-dense Wavelength Division Multiplexing-optical Wireless Communication System under Different Weather Conditions
This paper proposes an analytical model for evaluating the performance of dense wavelength division multiplexing (DWDM) for all optical orthogonal frequency division multiplexing (AO-OFDM) optical wireless channel. The investigated performance for proposed system is evaluated for the parameters bit error rate (BER) and Q factor .The constellation diagrams, and bit error rate (BER) of the recei...
متن کاملFault Tolerant Dense Wavelength Division Multiplexing Optical Transport Networks
Design of fault tolerant dense wavelength division multiplexing (DWDM) backbones is a major issue for service provision in the presence of failures. The problem is an NP-hard problem. This paper presents a genetic algorithm based approach for designing fault tolerant DWDM optical networks in the presence of a single link failure. The working and spare lightpaths are encoded into variable length...
متن کاملAnalytical Models for All-optical Networks Employing Wavelength Division Multiplexing and Wavelength Conversion
This work studies the e ect of wavelength converters at nodes of a wavelength division multiplexed all-optical network. We develop analytical tools to calculate blocking in a network with arbitrary converter placement and a general loading scheme. Exact and approximate models to calculate blocking on short paths are derived and used to build recursions for longer paths. A measure of the network...
متن کاملVariable neighbourhood search for resolving routing and wavelength assignment problem in optical wavelength-division multiplexing networks
Since the issue of finding optimal signal routes imposes itself as one of the main challenges within the framework of optimal networks, this paper aims at illustrating the development of a new, mixed-integer mathematical model for solving the static routing and wavelength assignment (RWA) problem in optical WDM networks and presents the comparison of results obtained by heuristics and CPLEX com...
متن کاملFiber-wireless networks incorporating wavelength division multiplexing
Broadband wireless access operating in the microwave and millimeter-wave frequency windows has been actively investigated for future ultra broadband communications. The drastic increase in the throughout of each base station in these systems necessitates the use of an optical fiber backbone to provide broadband interconnections between the central office and all the antenna base stations. With ...
