The Networked Enterprise

Networking The Organization
Telecommunications and network technologies are internetworking and revolutionizing business and society. The Internet, the Web, and intranets and extranets are networking business process and employees together; and connecting them to their customers, suppliers, and other business stakeholders.
Companies and workgroups can thus collaborate more compete successfully in a fast-changing global economy. The Concept Of A Network
The term network means an interconnected or interrelated chain, group, or system.
Examples of networks: a chain of hotels, the road system, the railroad system, the members of an organization, and computer networks, and so on.
The concept of networks can be expressed as a

    The telecommunication wireless industry is defined by its ability to operate and maintain switching and transmission facilities to provide direct communication through radio-based cellular networks. Services found in this industry include cellular mobile phone services, paging services, broad and personal communication services, and wireless public safety services. According to (IBIS World database), 52.2 percent of the products and services are segmented in cellular voice services. The telecommunication wireless is a 210.2 billion dollar revenue generating industry, with 43.7 billion in total profits. Over the past five years, this industry has experienced an annual growth rate of 2.6 percent and is forecasted to grow at 4.8 percent during the next five years (IBIS World database). The major players in this industry include the following: Verizon Wireless, AT&T Inc., Sprint Nextel Corporation, and Deutsche Telekom AG (see Appendix ? for graphical breakdown of percentage market share).…

    The notion of a network implies nodes and links. The nodes can be people, teams or even organizations - networks operate at many levels. Common examples are distributed geographic teams in large organizations, or small organizations operating as networks to compete against large corporations. The links are the various coordination and "agreement" mechanisms. In a network, high degrees of informal communications (both face-to-face and over electronic networks) achieve success where formal authority and communications in hierarchical organizations often fail. Two way links and reciprocity across the links are what makes networks work.…

    Key words: Fiber Bragg grating , dispersion compensation, apodization ABSTRACT A wideband chirped fiber Bragg grating (FBG) dispersion compensator operating in C band is designed theoretically by numerically solving the coupled mode equations. The power reflectivity spectrum and dispersion characteristics of the chirped fiber Bragg gratings are analysed. In order to achieve wideband dispersion compensation with a low insertion loss, grating length, average refractive index change, apodization profile and chirp parameter of the grating should be precisely optimized. The chirped FBG designs achieved in this study have resulted in a negative dispersion of 4.95 ps/nm for a grating length of L = 10 mm and a negative dispersion of 9.76 ps/nm for a grating length of L = 20 mm with 16 nm bandwidth at around 1550 nm. recognized as a perfect alternative do DCF. The most significant advantages of chirped FBGs are low insertion loss, nonlinear effects and cost. The idea of dispersion compensation using chirped fiber gratings was firstly proposed by Qulette [4] and later demonstrated experimentally by Williams et.al. [5]. A fiber Bragg grating is a reflective device composed of an optical fiber that contains a modulation of its core refractive index over a certain length. The grating reflects light propagating through the fiber when its wavelength corresponds to the modulation periodicity. In a chirped FBG, the periodicity of the induced index modulation varies along the grating’s length. As the grating period varies along the axis, the different wavelengths are reflected by different portions of the grating and accordingly are delayed by different amounts of time. The net effect is a compression of the input pulse that can be tailored to compensate for the chromatic dispersion accumulated…

    By all industry accounts, this statement is very accurate. In order to remain competitive in domestic and global markets, businesses have become very dependent on telecommunications technology in order to compete. This trend will increase even more so as we proceed through the 21century. Businesses are pushing and demanding for greater methods of access and efficiencies to communicate, transmit, collaborate, and access massive amounts of information. They want more efficient methods in telecommunications, networks, transmissions, speed, and flexibility to choose options that meet their needs. Technology are a critical tool that organizations are using to enable them to make crucial decision-making which can affect the viability of the organizations.…
