INTRODUCTON

Development of Dietary fiber Optic

In the late 1800s, the first studies of fibre optic were made. Alexander Graham Bell is the one who arrived with the idea of carry optical marketing communications sign by using wine glass fiber. The sensible development begins in the first 1960s and strongly produces until today. In the first 1960s, laser was developed and used for fibers optic. It really is followed by the introduction of low damage optical fibre in 1970s. The creation of the first very clean glass of fibers optic in 1970's has spurred the development of fiber optic. Fiber optics is developed swiftly in the 1980s where optical fiber content amplifier was invented. In 1990s, in-fiber Bragg grating was invented.

Characteristic of Fibre Optic

Fiber optic is long, transparent, flexible fibres of glass or clear plastic. Optical cables are developed when hundreds or a large number of fiber content optics are organized in bundles. By using optical cable, light signals can be sent over long distances. Fiber optics which made of very pure goblet are able to bring light over long distances which range from a few centimeters to more than 160km with little dimming. Some methods of fibres are less than 0. 004mm in diameter; they are simply even slimmer than human mane.

Besides, fibre optic bundles can be either coherent or incoherent. Within a coherent bundle, materials are organized so that images and illumination can be transmitted. Whereas, in incoherent bundles, the fibers are not set up in virtually any particular way in support of lighting can be sent.

Structure of Dietary fiber Optic

The structure of a fiber optic contains main, cladding and buffer finish. The main is the slim glass centre of the fiber where in fact the light moves. Cladding is the outer optical material bordering the main which demonstrates the light back into the core to avoid light from leaking from the main. There is a plastic layer that helps to protect the fiber from destruction and moisture called buffer finish. A coat which is the cable's outer covering gets the function of safeguarding the bundles of dietary fiber optics.

1. 4 Types of Fibers Optic

There are two classifications of fibre optics which are single-mode materials and multi-mode fibers. In single-mode fibres, light follows an individual way through the main and is suitable for high-speed transmission long-distances transmission. They allow light only across the axis of the fibers. They have got smaller cores and transmit infrared laser light. In multi-mode fibres, the light takes many pathways through the core. They have larger cores and transmit infrared light from light-emitting diodes (LEDs). Normally, the multi-mode materials are being used for short-distances communication.

1. 5 Fiber content Optic Communication System

Fiber optic communication is a way which sending pulses of light to transmit information by using a fiber optic in one spot to another. In dietary fiber optic communication system, the light propagates through the fibre predicated on the laws of optics. First of all, source information is fed so that information transmission such as words or video recording is converted into a form compatible with the communication medium. A coder or analog-to-digital converter (ADC) is utilized to convert suggestions signals from continuous analog signals into some digital pulses which are used to flash a powerful light source off and on very rapidly. The light-beam pulses are made and fed into a fiber content optic wire for transmission. After the light pulses coming into one end of the fibers, the boundary of the dietary fiber is stroked and mirrored inward. When light pulses travelling through the fiber content by means of zigzag reflections until they reach the other end of the fiber content. To identify the light pulses, a photocell or light detector is employed at the recipient which in turn will convert the light pulses into electrical power signal. The electric pulses are amplified and reshaped back to digital form which then will give food to to a decoder or digital-to-analog converter (DAC) to recuperate the original speech or training video.

Applications

Fiber optic is widely used in a number of of fields. It really is most popular found in communication system for data transmitting purpose. For instance, the telephone moving over in office is associated with optical-fiber cable. Besides that, in order to provide information worldwide, many communication companies have installed large systems of fiber-optic cables over the continents and under the oceans.

In medicine, medical doctors may work out with very small incisions to look and work inside your body of patients instead of needing to perform surgery. Endoscopes devices which have fiber optic are being used for viewing the hollow organs in the body. Normally, there are two collections of fibres in endoscopes where the outer ring of incoherent materials work as light supply as the inner coherent bundle transmit the image. For instance, an arthroscope is used by physicians to look at shoulder blades, knees, and other joints. There's a third set of fibers which are found in some models which used to avoid bleeding or even to burn away diseased tissue by transmitting a laser beam. Another example is the fact fiber optic can be used to measure body conditions. Besides, an instant and accurate evaluation of blood vessels chemistry also can

Fiber optic also plays an important role in medical research and making establishments. Optical-fiber coils used as sensing device in some instruments. It can measure the guidelines such as pressure, heat range, acceleration, and voltage. When the parameter changes during the transmitting of light above the fiber, it'll cause a measurable change in the properties of the light. Fibers optic devices also helpful in transmitting light to or from places where individual difficult to attain or dangerous, for case, unsafe areas, vacuum chambers, and restricted places within machines.

Advantages of Fibers Optic

There are lots of benefits of fiber content optic communication system. To begin with, it offers wider bandwidth because fiber content optic cables have higher information-carrying ability. Next, fibre optic exhibits low attenuation, thus, alerts can be transmitted over long distances. For instance, in subsea communications, signal can be transmitted ranges up to 280km without the requirement for repeater or boosters. Another gain is that fibre optic is a lot lighter, it is well suited for use in those areas where low weight is crucial such as plane.

With the benefit of smaller in proportions or diameter of dietary fiber optic cables than electric cables, so that more can be within an inferior space. Dietary fiber optic cable can also support more weight than electronic cables. Besides, fibre optic is highly secure in data transmission by reason of fibre optic cables do not radiate any signal which means that the optical signal is completely contained in the midsection of the fiber. Military and authorities communications are suitable to use fibers optic for communication goal due to enhance data security.

In addition, fibers optic communications cable connection does not bring electricity and also not susceptible to lightning due to its non-metallic cables. It also has better immunity to external affects and interferences. Finally, fiber optics is environmentally friendly. Because of the lightweight, compact characteristics of dietary fiber optic, there is certainly little use of resource in manufacturing, moving, and installing fibers optic cables.

Disadvantages of Fiber Optic

On the other side, there are also shortages of fiber optic. Specialist skills are necessary for installing fibers optic, especially in the testing and terminating phase. High cost of fibre optic cable is because of the issue of manufacturing it and installation. Therefore, costs will decline as methods improve.

Furthermore, if compare to mailing an electrical sign down a copper cable, the costs for converting an electrical indication into an optical sign for transmitting down a fiber and converting transmission back into a power sign is higher. Besides, data transmitting via fibers optic is susceptible because of a sizable quantity of information hauling capacity of the fiber. This might lead to catastrophic lack of communication. The disadvantage of cannot bring electrical energy by fibers optic has significant implications to the subscriber where electricity is need to help make the mobile phone work so that wire is needed for power supply.

ENVIRONMENTAL FRIENDLY APPLICATIONS OF Dietary fiber OPTIC COMMUNICATION

2. 1 Submarine Fiber-Optic Communication Cable

The reseach on the environmental impact of submarine fiber-optic communication cables was carried out by Craig Denovan. From his review, he found that only fewer resources needed to install per unit duration than the underground terrestrial.

The benefits of employing this optic cable are the data can be transmitting within an effective manner and it has small environmental impact per unit of data directed.

This optical cable is an environmentally friendly since it was only release 7g of carbon dioxide equivalents for each gigabit of data directed along 10, 000 kilometres in an average 13 many years of commercial lifespan. The upgrade terminal equipment will be increased the data capacity of the modern cable while the existing cable television can still be use.

The 10Gbps of transmission data will be replaced by the 40Gbps data transmission. Thus, increase the environment performance and the amount of possible contacts per transmission increased. It is also would reduces its potential environmental impact as well as more data can be dispatched by stretching 13 years of cable life time.

Fiber Optic Sensor

There is lots of applications utilize distant sensors, coaxial cable, transducers and other communication devices that subject matter electronic to high RF, EMI or magnetic domains high voltage levels. It can cause a misuse energy power and not environment friendly using the tranditional communication system. However, almost all engineering make an effort to increasing the use of renewable learning resource materials while lessening reliance on petroleum - founded materials in new structure is a major concern of todays. To be able using the right ways of enhancing energy efficiency, minimizing CO2 emissions, increasing interior environmental quality and safeguarding the natural resources of the world. There are a few internationally recognized qualification organizations coping with these issues because it becomes so important in development. Besides that, architects are constantly looking for opportunities to reduce electrical and petrol consumption, increase air quality and use more eco-friendly materials in building construction to handle these concern. Through the use of Motorola's Passive Optical LAN, an all-fiber LAN solution that performs on the gigabit passive optical network is a respected alternative to the traditional LAN network that enables architects and design designers to improve the use of eco-friendly materials while significantly lowering energy use and significant costs associated with traditional LAN architectures.

Passive Optical LAN

Motorola offers another choice for LAN treatment for copper-based systems. This technique was known as Passive Optical Lan. It based on proven Passive Optical Networking technology that is expanded by leading provides across the world. It play important role to give better service to customers. This system also provides enterprises with fibre optic connection to any Ethernet end point such as person devices, access points and cellular controllers, application serves and printers. It makes great updating copper - established cables and device in the traditional LAN setting up with fibre optic equipment. The Passive Optical LAN network includes a higher density aggregation device in the primary telecommunication room that provides converged service over a Gigabit Passive Optical Network. It reaches the desktop terminates at a Work Group Terminal. The Work Group Terminal provides 10/100/1000 Base Ethernet connection equipment such as desktop computer or laptop computers. Passive Optical Lan provides small unaggressive dietary fiber optic splitters which can be allocated in a building. It require no electricity, produce not high temperature has typically 2 to 4 cubic feet in size. The POL system also reduces overall electric power and chilling requirements and reduces the need for structure materials that are not environmentally friendly. This enables design engineer to reduced cost on framework and interior with extra advantages to both customer and environment. For cases, research facility using POL system will results in a reduction of 8, 000 pounds less plastic versus category 6 copper infrastructure and 28, 000 pounds less plastic to a category 6A copper infrastructure. Therefore, design engineers enables to create a building with a 50% decrease in power ingestion for the entire computer network using POL system. This POL system will advantage to architects to create a building with lower set up cables, maintenance and equipment cost.

Meanwhile, fiber content optic sensors is was an improved choice replacement for existing sensors where in fact the fibre sensor offer higher performance, safeness and cost benefits to the end consumer. The fiber content optic sensor has huge demand in new market whereby it still in development and deployment new technology to displace older technology. For instance, fiber sensors were developed to support process control in developing field. The selling details of advantages having these sensors are improvements in environmental ruggedness and safeness, especially in areas where electronic discharges could be dangerous. In other way, fiber optic sensors are being mass-produced in the field of medicine where they can be used to measure blood vessels gas parameters and medication dosage levels. Patient protection is assured as they'll not expose from electrical power shock treat credited to fiber optic sensor is unaggressive to electricity. Therefore, dietary fiber optic sensor technology was not applied in the automotive industry, engineering industry and other relative users of sensors because of cost concerns. This can be expected to change as the improvements in optoelectronics and fibre optic communication continue steadily to expand along with the continuing introduction of new fibers optic sensors.

CONCLUSION

The primary reason on using fibre optic communication could it be is may be used to copy data in a long distances. The fiber optic cable is way better than conventional cable television in conditions of wider bandwidth, lower damage, light-weight, small size, power, security, interference immunity and safety. It is also have a weakness which is hard to work with because it's small size and brittleness. Additionally, fiber content optic cables are produced from glass which includes the lowest reduction but is brittle and also made from vinyl which is cheaper and even more flexible, but has high attenuation.

Due to the reasons of fibers optic has more advantages over standard cable connection in data transmitting; copper cable communication has been basically replaced by fibers optic in network.

For future technology, there exists one new machine created by Fraunhofer Institute for Development Technology in Germany that can produce dietary fiber optic film sheets. This fibers optic film bed linens can be apply extensively including exhibits, architectural light, and vehicle interior lighting.

Further development of fibre optic wire in communication should be continuing since it is more environmental friendly compare to the traditional communication cable. Apart from having greater bandwidth of information transmission, we can also reduce impacts to the surroundings.
