Objective: Optical networks exploit the Wavelength Division Multiplexing (WDM) to meet the ever-growing bandwidth demands of upcoming communication applications. This is achieved by dividing the enormous transmission bandwidth of fiber into smaller communication channels. The major problem with WDM network design is to find an optimal path between two end users and allocate an available wavelength to the chosen path for the successful data transmission.

Abstract With the rapid development of multi-source optical multicast application, the wavelength division multiplexing (WDM) with limited number of wavelength channels is facing with the new challenge of bandwidth shortage. Optical multicast adopting network coding can improve the bandwidth utilization, but optical network coding needs to increase optical storage and computation overhead in WDM optical network. For reducing the number of optical network-coded links, an improved adaptive genetic algorithm (IAGA) is proposed to minimize the number of network-coded links for multicast. By design

Abstract:

A high-capacity, flexible, cost, and energy efficient backhaul network based on the convergence of optical and wireless technologies is proposed this research work. The proposed backhaul network, which is deployed on wavelength-division multiplexing passive optical network (WDM-PON), supports three backhauling solutions including pure WDM-PON, hybrid WDM-PON/free-space optics (FSO), and hybrid WDM-PON/millimeter-wave (MMW) radio frequency (RF). We firstly have developed mathematical models for performance analysis of the downlink for three comparative backhaul solutions. We then theoretically

Abstract:

The issue of WDM network traffic grooming has been a hot in the field of research. The implementation of traffic grooming technology can improve the utilization of wavelength channels, reducing the link delay and the blocking rate of the network, which to improve network resource utilization and optimize network performance. This article mainly studies all-optical network routing algorithm utilizing WDM technology to achieve the dynamic traffic grooming and propose a optimization grooming policy -HaffmanGroom (M) algorithms which based on SONET / WDM ring network.

Abstract:

The advent of nodal elements, such as Optical Add/Drop Multiplexers (OADM) for Wavelength Division Multiplexed (WDM) networks, has led to a myriad of possible network architectures for the optical layer. In this project we design and simulate a WDM-OADM optical ring system of four nodes, two wavelengths on unidirectional single mode fiber at data rates of up to 10 Gbps. We use a continuous wave laser as a source for each channel with external modulation. The performance of the system is reported on the basis of eye diagram, Bit Error Rate (BER) and Q-factor. Optisystem software is used to simu

Abstract:

In this paper, we analyse the optical burst switched (OBS) network, discuss the OBS node architecture. In OBS network, to construct a good data structure is very important. The OBS incoming data are assembled into basic units, referred to as data bursts, which are then transported over the optical core network. As to the OBS signaling, it is performed out of band by control packets that carry information such as the length, the edge-node-destination address. OBS is a promising solution for the all-optical WDM networks.

Abstract:

We study the blocking probability and performance of single-fiber and multifiber optical networks with wavelength division multiplexing (WDM). We extend the well-known analytical blocking probability model by Barry and Humblet to the general model, which is proposed for both single-fiber and multifiber network paths with any kind of wavelength conversion (no, limited, or full wavelength conversion) and for uniform and nonuniform link loads. We investigate the effect of the link load, wavelength conversion degree, and the number of wavelengths, fibers, and hops on blocking probability. We also

Recently, wavelength division mulplexing (WDM) technology has been extensively studied, and various WDM-PON architectures have been proposed for next-generation passive optical network (PON). In this paper, we combine the TDM with WDM architecture to achieve high-speed, long-distance transmission. To reduce the cost of ONU, we achive the colorless ONU by placing a Reflective Semiconductor Optical Amplifier (RSOA) in the uplink transmission. We build the whole architecture to simulate the Hybrid WDM/TDM PON System in Optisystem and the experimental results prove that the architecture is feasibl

Abstract:

We address the problem of allocating optical bandwidth to a set of communication requests in a tree-shaped all-optical network that utilizes Wavelength Division Multiplexing (WDM) technology. WDM technology establishes communication between pairs of nodes of the network by establishing tranceiver–receiver paths and assigning wavelengths to each path so that no two paths going through the same link use the same wavelength. Optical bandwidth is the number of distinct wavelengths. The important engineering problem to be solved is to establish communication between pairs of nodes so that the total
