Improving the efficiency of light distribution in PON for service delivery in Fiber to the Home (FTTH) environments - Article Example This is true in wide area networks (WANs) that provide connectivity between cities and in metropolitan area networks (MANs) that connect telco operators’ nodes within cities. However, most local loop or the â€Å"last mile† that serve residential, small business or enterprise users, have not benefited from this. The local subscriber lines for telephone and Internet are still using twisted copper pairs while cable television subscribers are still using copper coaxial cable [1]. With the increasing users’ demands for services such as Internet applications, VoIP, interactive games, high-definition television (HDTV) and video on demand (VOD), the â€Å"last mile† connection has become a bandwidth bottleneck. Developments in xDSL and cable TV technologies has in some extent addressed this problem but still not enough to meet the continuously increasing bandwidth demand. A more effective solution is gradually being put in place especially in urban areas by extending the fiber to the user. This technology is called by many names depending on the termination mode – fiber to the home (FTTH), fiber to the curb (FTTC) or fiber to the building (FTTB). All of these FTTx solutions may utilize the Ethernet Passive Optical Network (EPON) distribution technology. This system utilizes bandwidth allocation algorithms to allow efficient sharing of limited upstream channel bandwidth [2]. Different methods of implementing this will be discussed in this art icle. An EPON system is a point-to-multipoint fiber optical network with no active elements in the transmission path from the source, an optical line terminal (OLT), to the destination, an optical network unit (ONU). It can use different multipoint topologies, such as bus, ring, and tree. The most typical architecture is based on a tree topology and consists of an OLT, a 1:N passive star coupler (or splitter/combiner), and multiple ONU. The OLT

Potential oppotunities n challenges wat doesthe company view as opportunties and minimize challenges - Essay Example The fast changing environment of technology has necessitated the Hewlett Packard to meet the challenges of emerging new technology in mobile. While HP has been a leader in the computer technology and related areas, it needed to be creative in its diversification and introduce new gadgets to compete with its rivals like Apple Inc, IBM, Sony and Nokia. Palm provided HP with the opportunity to gain a competitive edge against its rivals. The three major opportunities that Palm gained through its merger with HP can be described as below: Brand creation is a major marketing technique that has massive support within and outside the business community and management strategy. ‘Brand building is needed because products are the same’ (Kotler, 2005). The brand name ensures that the product maintains a high standard of excellence at a price that a customer is willing to pay for. Therefore, the brand provides the customer with a quality product which satisfies his needs, making it as one of the key reasons that brands still enjoy the popularity amongst its customers and at the same time, attract fresh clientele. HP is an established international brand and a leader in business computing. Palm is handheld computing device with multiple functions. It is an extremely useful device for executives who are constantly on move and who are looking for gizmos which are small enough to hold in their pockets but powerful enough to be used as computer, or phone or even as an entertainment device, as and when the need arises. Globalization has changed the dynamic of the business and today the professionals need to have all the information at their tip while following a hectic schedule. So the smaller the device which can pack such features, better are its chances of capturing this target group. Hence, Palm’s association with HP would greatly enhance its brand value. Financial considerations are strong motivating factors that promote strategic
