Advantages And Disadvantages Of Optical Fibers

Advantages And Disadvantages Of Optical Fibers A light travels in straight lines as we know it is highly impossible to make it follow a curved path to glimmer around corners. In 1970s there was a great improvement and faster growing in fibre optics communications. The main idea of light in communication system is evolved from simple signal fires and lamps. Claude chappe has a first modern attempt in optical telegraph built in the 1790s.The first problem was alleviated with the advent of semiconductor age, the semiconductor laser invented by Theodore maiman in 1962 LED(light emitted diode) is improved in optical fibre which solved the problem o0f passing light through air. The communications through optical fibre was proposed in 1966 by Charles Kao and Charles Hockham of the standard telecommunication laboratory in England. In the past few decades many technologies are introduced among them optical fibre communication is the best communication system. The main components of optical fibre are core, cladding and coating. The main duty of core is, it carries a light from transmitter to receiver. Core: It is a smallest part in optical fibre communication system. It is very delicate optical fibre cable Generally it is made up of plastic or glass. The core made up with glass is mixed with pure silicon dioxide other impurities like germanium or phosphorous. These impurities are added to improve the refractive index at certain conditions The range of glass core is from 3.7 µ to 200 µ. 1.48 is the refractive index of core The core made with plastic is larger than glass. Cladding: It is the protective and surrounded layer of core. It provides the low reflective index. In glass cladding the core and cladding is made with same material Different quantity of impurities is added to both core and cladding in order to make a difference in refractive index among them is about 1%. 1.46 is the refractive index of cladding 125 µ and 140 µ are the standard cladding diameters Coating: This is the main protective layer for the entire optical fibre. It protects the optical fibre from shocks and other external damages. Coating has an outside diameter of either 250 µ or 500 µ. Coating is colour less but to identify the coating in some applications it is coloured. 2) Advantages of Fiber optics: The band width of optical fibre is very high when compared with other communications. To increase band width in fibre optics is very easy. Data transmission is very fast in fibre optics. We can transmit data to longer distances without any noise. It is very difficult to tap the information because it is much secured. 3) Disadvantages of Fiber optics: Installation of fibre optics is very cost. When we face any problem with fibre optics we require special test equipment. Communication with fiber optic cable is more cost when compared with different broad band connection costs. In rural areas fiber optic communications are very less, in these days this is one of the main disadvantage of fiber optic. 4) Fibre Optic Losses: Due to bending and breaking of optical fibre cables losses are occurred in fibre optics. Mainly there are two types. Intrinsic losses. Extrinsic losses. 4.1) Intrinsic losses: A slight variation from one fibre to another fibre even manufactured with in specified tolerances. Losses are occurred by these variations. In Intrinsic losses there are four types of losses. They are NA (Numerical Aperture) mismatch losses. Core diameters mismatch losses. Concentric mismatch losses. Elliptical mismatch losses. Cladding diameter mismatch loss. 1) NA (Numerical Aperture) mismatches losses: If there are two optical fibres are repaired we are connecting them with splices during this connection mismatches are occurred because the cone of acceptance in the receiving fiber cannot gather the complete light emitted by the transmitting fiber. This means the light is not travelling completely. This mismatch loss is known as numerical aperture mismatch loss. 2) Core diameter mismatch losses: The difference between the core diameters is the reason of this loss. When the transmitting core greater than the receiving core or transmitting core is lesser than the receiving core light is not completely travelling. This type of mismatch is called as Core diameter mismatch losses. 3) Concentric mismatch losses: In ideal conditions the core the core and cladding are concentric, that means a single geometric centre is shared between them. The fibre core is likely to be offset by a slight amount from the cladding centre. In fiber cores when the transmitting and receiving are non concentric. They will not meet exactly and the light coming from the transmitting fiber is lost. 4) Elliptical mismatch losses: If the fiber cores not the perfectly circular and fiber cores and cladding are not perfectly concentric this types of losses are occurred. The transmitting optical fiber core is not match with receiver core. 5) Cladding diameter mismatch loss. If the diameter of the cladding are not same on the both fiber optics. This type of mismatch is occurred. This means the transmitter light is not completely sending to receiver core. 4.2) Extrinsic losses: Generally in an ideal optical fibre the cores are centred on each other they are placed at 90 degrees angle to their faces. The ends should be in firm contact. Any miss arrangement in these conditions can cause some loses in the signal. There are three types of extrinsic losses. Lateral displacement. End separation. Angular misalignment. 1) Lateral displacement: If the centres of core of two optical fibers are do not match this loss may occur. If the displacement increases less light from the transmitting fiber makes its way into the receiving fibre. A little amount of displacement is acceptable in larger fibers because the majority of the core s surface area is still in contact. In smaller fibers a slight offset can place the centre of the transmitting core entirely outside of the receiver core. 2) End Separation: The end separation loss is due to Fresnel reflection, it takes place when the light passes from fiber refractive index into the air and vice versa. In refractive index each and every change causes an amount of reflected light and therefore the loss is occurred. 3) Angular Misalignment: The optical signal will suffer from these losses when the fibers meet an angle. The solution for this loss is to arrange the fibre end properly that the both ends are in the same line during splicing. 4.3) Major causes of losses: Absorption loss. Scattering loss. Linear scattering losses. Non Linear scattering losses. Coupler losses. Insertion losses. Reflection losses. Impurity losses. Macro bending and micro bending losses. Packing fraction loss. Absorption loss : Absorption loss is occurred by the impurities in the fiber it self such as water and metals. Material absorption losses: Material absorption losses are occurred by absorption of photons within the fiber these losses represent a fundamental minimum to the attainable loss. Intrinsic absorption losses: Interaction with more than one component with glass leads to the intrinsic absorption loss. Scattering loss: I couples energy guided to radiation modes which causes the energy losses from the fiber. If there is a core diameter irregularity in fiber access direction also a reason of scattering losses. Linear Scattering loss: The quantity of light power is transferred from wave is directly proportional to the power in the wave it also causes by inhomogeneties in the glass when the size of it smaller than wave length. Non linear scattering loss: If the electric field with in the fiber has high values then it leads to the presence of non linear scattering ,it also causes when significant power is scattered in all the directions. Coupler loss: The fiber optics coupler are active or passive devices the coupling loss in optical fiber is defined as, = output power =inputpower Connection losses increased by fiber to fiber connection due to the following sources of intrinsic and extrinsic. Mainly we have four types coupling losses 1.Reflectionlosses. 2.Fiber separation. 3.Fiber misalignment. 4.Fiber mismatch Insertion losses: Insertion losses are combination of coupling loss and additional fibre losses. If joints of fiber can increased the attenuation of fibre this is done in multimode operation. Fiber joints can leads to the second order mode in single mode fiber. Reflection losses: Light waves of reflection and transmission occur because frequency do not match the natural resonant frequencies of vibration of object. Impurity losses: The first source of impurities material in glass fibre is metallic ions, the loss due to this reduces the contribution below 1DB/KM. Macro and microbending losses: These loss may occur due to sharp bend in fibre, to produce high losses a short length of optical fibre is to be bend, as tight as the fibre optic the losses are worst. The major problem in macro losses is in the hands of the installer.The losses in micro bends is same as the macro bands but it just differs in the size and cause. The radius is equal or less then the diameter the outer layer will shrink and get shorter when the fibre is too cold, fibre optic cables are available with a range of temperatures from C to C. Macrobend Microbend Packing fractin losses: Single emitter sometimes uses a bundle of fibres, if claddings are in contacts many fibres are packed together. Large area source can match a large bundle in order to eliminate area mismatch loss. Small sources can emit less like than the larger once , in single fibre larger one has more power to couple into a bundle than into a single fibre. Fibre optic as a sensor: Sensor provide link to interface between the electronic units and physical world the sensor can detect physical and chemical qualities such as temperature, pressure, vibration, flow , acceleration, proximity,and chemical concentrations. A basic sensor is made upof a light source(laser or led), a length of fibre and optical detector. Fibre optic itself acts as a sensor by varying he intensity of light these measurements are done. Only the source and the detector is required in the sensors hence it is very simpler. Based on the performance characteristics there are four different types of sensors they are 1. Extrinsic sensors. 2. Intrinsic sensors. 3. Fibre bragg grating (FBG sensors). 4. Long period grating sensor. Extrinsic sensor: In extrinsic sensors the outside part of the fibre undergoes to the sensing effect. The fibre acts as a collection system in light delivery. For example a chemical sensor utilizes a sensitive material on the tip, light is passà © through the fibre and reflected back. In the chemical solution as the concentration changes the tip properties may change and the reflection of the light also changes which gives the measure of chemical concentration. Intrinsic sensor: In intrinsic sensor the changes takes place within the fibre. The change is outside the fibre and the fibre remains unchanged when the intrinsic sensor is in contract to extrinsic sensors. For example when a fibre with ruff surfaces is placed between two plates, the fibre is pressed by the plates when the pressure increases the attenuation of the fibre increases due to this. Bend and micro bend sensor: Bent in a optical fibre leads to a portion of propagating light beam along the bend is incident at angles must be smaller than the critical angle by which attenuation, this can be used for sensing measure load and stream are found by this mechanism, lose of power occurs if any load lead to a bending of fibre. This measure gives the distribution of strain and load with the use of lost power. A series of random bends and small bends along the fibre is known a micro bending. It acts as a coupling between cladding and core modes in a single mode fibre and between multimode fibre. Fibre bragg grating(FBG Sensor): TO MEASURE TEMPERATURE AND STRAIN: To measure sensing mechanical strain, temperature and acceleration we use FBG sensors. Parameters that changes any of these results in a change in reflected wavelength, these changes when measured, sensing or external perturbations can be done. Long period grating sensor: Periodic perturbations along the length of the fibre with periods greater than hundred micro meters which includes coupling between the light propagating in core and cladding is long period grating. Cladding code influence the power transmitter through the fibre used to find the refractive index when there is any change in the medium around the fibre. Interferometric sensors: # In this the light is transmitted through to fibres. one of them (reference arm) isolated from environment and its properties are constant. And another fibre (measure arm) is exposed to parameter during sensing. The face of the light is changed by the parameters. The interferometric sensors has the greatest sensitivity and it has highest performance capabilities. The Interferometric sensor. ( John F.R, 1997, pp-543). ADVANTAGES OF FIBRE OPTICS SENSORS: It allows an access to normally inaccessible areas of interest. It is an non-electrical. Due to small size and less weight of the sensors it effective in cost. It has high sensitivity. It has high reliability. It is very easy to install. Transmitter: Transmitter converts electrical signal into light signal. It has two functions Light emitter Regulator Light emitter: It works as a soirce of light coupled into optical cable. Regulator: It modulates the light to represent the binary data. Light emitting diode: The transmitter are directly modulate when the drive current passed through the LED is varied. The power is directly proportional to the current flowing in the LED. According to the applications the drive currents is measured. The drive current is switched on and off in digital applications. And the current is varied in Analog application. The LED transmitter is packed with the receiver since the space is reduced and simplifies the circuit designing which reduces the cost. Characteristics of the LED: Recommended operating conditions. Electrical characteristics Optical characteristics Data rate Recommended operating conditions: It describe the temperature and voltage ranges that device can operate in without damage. Without any fluctuations the maximum and minimum operating temperatures can be measured. Electrical characteristics: It describes.. the required supply current Data output voltages Signal detect output voltages Rise fall times Optical characteristics: It includes Minimum optical input power Maxcimum optical input power Operating wavelength

Attention getter: Have you watched the news lately? Even if you haven’t, you still probably have heard something about the disputes in and around Jerusalem. These disputes have been going on for centuries. Many different groups of people have fought to control Jerusalem over the years but we are going to focus on the current majority parties from today. From the information I found on CNN.com and the Jerusalem Post, I concluded that the Israelis and the Palestinians are currently fighting over who should control Jerusalem and how it should be run. The major problems between these to groups started in 1948 when the British Mandate partitioned Palestine into separate Muslim and Jewish states. Now, Palestine is majority Muslim while Israel is mostly Jewish. Well, under the Mandate, Jerusalem was given to the Jews to control by the UN as a reimbursement for what their people went through during WWII. This made the Palestinians mad because their third holiest mosque is now in a fo reign run state. The Jews are mad because now they control the land but cant do what they want. They want to build a new Hebrew Temple of Solomon to replace the one that was destroyed a very long time ago. The big problem is is that the exact location of where they want to put the temple is in the exact location where the Muslim’s mosque is located. That’s not all they are fighting about however. They are also fighting about how Jerusalem should be governed. Israelis want to keep it free for all religion...

The call centre is a central information point, which the rest of the company can use to gather data about the relationship between companies, products and customers. Murphy Brewery has 9,000 customers base. The problem with them is that their customers were presented with various points of contact within our organization without any one individual taking responsibility for a specific order, query, or request. Customers found that their requests and queries often went unresolved. This information was derived through conducting a self-commissioned survey. The solution was to establish a Customer Care service, i.e. a call centre, that would integrate all concerned information for any agent dealing with a customer. By understanding how customer trends are moving, a company can control the bases of their existence, their customers, and thus maintain a competitive edge over their rivals like Murphy Brewers. This relates to CRM because it is providing the best customer service possible by knowing the customer needs. Activity 2: A Power Analysis of your position Activity 3: Research Enterprise Resource Planning (ERP) and Benchmarking. The definition of ERP is an attempt to integrate all departments and functions across a company onto a single computer system that can serve all those different departments' particular needs. It facilitates communication and enables information to be shared more easily. In the business sense for example, if an order is made, it can be done with all the information about the product or service being ordered available and by eliminating the need to go into different departments, it saves time. Benchmarking involves setting a baseline against what a company should have done or being doing to remain competitive. This follows certain criteria such as portability, flexibility, geographical application, facility of integration and facility of implementation. PeopleSoft run a client server architecture supporting Windows, cell phone technology (WAP), Unix, Linux and Macintosh. They are able to cater for industries, the federal government, Healthcare, manufacturing, Higher Education, Retail and Utilities. This shows an ability to tailor packages for almost any given enterprise. PeopleSoft can implement applications that can handle enterprises on a world wide basis.Facility of integration They offer an open integration platform to connect your enterprise to almost any form of enterprise which links to their application on worldwide basis.

Facility of integration All major departments can be integrated into a large software solution. Facility of implementation Support provided after the software package has been purchased by a company. Activity 4: Profiling a Strategic team: Executive EQ test The company mission statement appears to be the best British garden magazine. They aspire to become the leading focus of expertise in garden designing, house decoration and culinary worldwide. For example, the service of providing gardening lessons through the Internet could be offered, and eventually they would expand into other educational areas. They seek to explore other medium attaining international coverage. A means of doing this could be by using SPY IN THE SKY services enabling HiMAC to take aerial photos of any garden and sell specialised tours. This would serve as a means to provide course over the Internet. This involved aligning financial activities and reports for all titles. In terms of business change, they proposed to have a team solely devoted to dealing with customer queries. They recognised the need for the customer base to expand in order to deal with a greater diversity of customers. They noted some supplier that could help the primary set up of computer based courses as a support if HiMAC took up more educational courses for other organisations. There was a recognition for the need of some departments to receive training for these new technologies. The accounting functions needed to be integrated into one single report. The decision to copy the model of an Internet based course from SurferTeaching Company was both good and bad. It was good in the sense that by copying, it reduced labour content with less work being involved than if one was innovative. It also provided less work by speeding up processes. It was bad in the sense that by copying another practice, it might not have been tailored for HiMAC as a specific company and thus caused problems like internal division. By not being specifically tailored for their company, its design would not cater for their CSF, goals and objectives. Secondly, the practice may carry inherent imperfections which HiMAC might not recognise and breed into their companies thus bringing new issues to consider.

The Technological Disaster of the Titanic essays

The Technological Disaster of the Titanic essays The sinking of the Titanic was the first major technological disaster of the twentieth century. What went wrong? Could this tragedy have been avoided? Today, in the 21st century with ever-advancing technologies, we've been able to solve many of the mysteries of the sinking of the Titanic. With newly discovered information, we can explore the specifics of why the world's most famous "unsinkable" ship helplessly sank below the surface of the freezing cold Atlantic Ocean in April of 1912. Human neglect had to play a huge role in this event. And in that case, why? I will be analyzing these ideas about articles read in class throughout the paper. In the article, Technological Momentum, Hughes suggests that technology is shaped by society. I believe this stands true in the case of the Titanic. The fact that an inadequate number of lifeboats road on the Titanic because of the desire for glass-enclosed observation lounges, suites, and palm courts for wealthy travelers is an example of this. The technology for more lifeboats was there but was not used because of society's desire not to use them. The boat itself (technology) was designed to hold the riches people on the planet (society). Its grand facilities included a swimming pool, a squash court, and a Turkish bath, among other things. This shows how technology (Titanic) is shaped by society. Society was then shaped by technology when the technology failed. If anyone of the numerous actions that could've saved the ship would have taken place, then part of society wouldn't have perished that day, and the rest of society wouldn't have mourned that next morning and there on out. We would've then never learned the invaluable things we did because of this tragedy. In response to Berry's question, "even if we can build it, should we build it," in my opinion. Generally, the answer to this is yes. Granted, there are times when the consequences of creating something out-weigh the benef...

Unemployment Essay

Unemployment Essay Free Online Research Papers Each society has some factors that hinder its improvement. Unemployment is one of them that can prevent a society to be perfect or somehow a utopia. Unemployment can cause two major negative effects on society, which are poverty and crime. These two factors can make fundamental problems for society. When unemployment is widespread in a society, there would be no money gained, so the people of that society would be poor and poorer. Not only they get poor, but also they will face some other difficulties. For example, an unemployed, married man cannot afford his family expenses, so that would be the beginning of a depression, quarrel, and other disorders in the family. Poverty gives them a feeling of being inferior to others, so they will lose their self-esteem, which is more dangerous than the hunger they tolerate. The unemployed person will come to the conclusion that he is a nonentity in the world! This poverty itself is a cause itself; it can cause people to commit a crime. Crime is sometimes is done because or the poorness of a person who wants something which he cannot afford. When the pocket is empty and living in a megapolis is costly, those who are not virtuous resort to a way of gaining money, which is not righteous, such as stealing others’ possessions, murdering others for being paid, or even having a hostage in order to have ransom. Some others start smuggling gas, drugs, or other things which are illegal in a country. Poverty and crime are considered as major effects of unemployment in society. We can regard it as a very beginning cause of disorders in a society in different forms. It can make the unemployment of a society depressed, having a lack of self-esteem, and useless. Malnutrition, divorce, crime are other effects of this devilish phenomenon which is called unemployment.

Literature Review Essay Example | Topics and Well Written Essays - 2500 words

Literature Review - Essay Example After a thorough review of primary and secondary sources, their investigation revealed a difference between the decisions of budget cutback and information technology. Cost effectiveness was found to be an important criterion for making the decisions of budget cutback. These decisions took lesser time to be made and were quite volatile in their nature i.e. may alter with time. Here, number of participants was not affected by the content of decision. Contrary to this, cost effectiveness was found unimportant in the decisions of information technology, time consumed in decision making was longer and once made, decisions were generally permanent. This tells that the content of decision can have a great impact on the significance of various criteria, time consumed in the decision making process and the stability of decision. This finding contradicts the conventional understanding that cultivates in the minds of people regarding the factors that affect the process of decision making. In t he conventional understanding, the process of decision making is only controlled by the contingencies originating in the environment and the organization. 2. In his research, Nutt (2005) compared the decision making in the public sector with that in the private sector with the help of an experiment. To achieve this, decision making in a business company was compared with that in a governmental agency that was supported with tax. Practices and preferences of mid level managers were captured with the simulation in the public and private sectors. Managers involved in the study were required by simulation to estimate the risks and opportunities of acquiring budgets for the two sectors. In order to design the budget that would be sufficient for an organization functioning in a public and private sector, a cognitive culture was used which placed emphasis on the estimation and bargaining. A controversial and otherwise amount of budget was used for both the cases. Results of their research suggested that managers in public sector make use of networking and bargaining while those in the private sector make use of estimation and assumption. These results were consistent with the hypothesis that public sector managers prefer group decision making whereas private sector managers believe in individualistic capabilities. The research concluded that managers go for budgets that suit their individualistic cognitive style. The difference in the support of budget decisions in the public and private sector managers essentially speaks of the work culture that dwells in the two types of settings. Most works in public sector are done through networking and bargaining, whereas in the private sector, one has to rely on one’s ability and assessment to make the rational decisions. 3. In his research, Al Yahya (2008) studied an integrative multiple links model among three traits, namely the sharing of power-influence in making the decisions, work-related outcomes (WRO) and cultur e of Saudi Arabian organizations belonging to the public sector. These conceptual associations have not been explored much in the public sector organizations conventionally. Traits of competence as knowledge, ability and skill are used effectively in the participative practices as shown by the model of structural equation. This influences individuals’ thoughts about WRO that include but are not limited to

Country project - Term Paper Example Further, its poor political dynasty with dominant interest groups and shifting policies to cater for the politically dominant interest groups is reflected on investor’s behavior. At microeconomic level, investors portray a pervasive conduct on both exogenous and policy generated economic risks in relation to income and property. The political-economic has multiple structural vulnerabilities and weakness in their governance (Praeg 86). From time immemorial, Ethiopian economy is controlled by elite kings, usually described as slavery in modern world (Clarke 97-101). Private ownership of lands had never been heard of until 1970’s, with inequitable land holdings of the country under the slogan, ‘Land to The Tiller† where the state ended up owning lands itself instead of giving it to the people. Though the state controls land ownership, rural peasants and pastoralists are guaranteed a lifetime of â€Å"holding right†, while urban residents are guaranteed the right to get land for residence for 99 years lease based; these rights gives all rights to the people of Ethiopia except sale and mortgage right. However, from 1974 during the fall of emperor Hailesilassie, land remained public property despite earlier socialist oriented military government to make land property of the people and not the state. At the moment, Ethiopian economic growth is estimated to remain strong in year 2015 under the Growth and Transformation Plan. This plan aims at boosting agriculture as the heart of the country economic growth, promoting industrial development and aiding development of quality infrastructure. However, corruption is a key issue in Ethiopia. Historical background of economic policies reflects centuries of internal conflicts and external threats. Internally, varying customs, religions, and ethnicity served as focal points in the contest for power and control of economic resources (Adejumobi 187). Externally, regardless the fact that the country has
