Fiber optic history essays for kids

Low loss attenuation optical fibers together with optical so- urces led the efforts for enhancing the fiber-optic communication systems [6]. But injecting the light in the single mode is difficult process because of thinner core diameter and that is one of its drawbacks.

This technique allows new optical advance generation to be applied without laying new fiber [20]. Each optical node may act as a transceiver unit with multifunction. It weakens light in two ways.

Fiber optics are also used in the field of medicine, all of the wire- cameras and lights are forms of fiber optic cable. It is chosen for transporting very large amounts of data traffic over long distances in the telecommunication system.

From the bust of the dot-com bubble throughhowever, the main trend in the industry has been consolidation of firms and offshoring of manufacturing to reduce costs.

What are Fiber Optics?

Essay UK - http: The optical spread amount depends on the length of fiber and the bite rate [1] Over adequately long fiber the dispersion may cause intersymbol interference ISI whereas in high bit rate, two consecutive pulses are adjacent to each other causing difficulty in detecting the pulses and that means increasing in bit error rate BER.

This region is divided into 3 regions: Pulses need boosting, about every 6. Application layer is the top of this model which contains voice, video, and data services.

In guided lightwave system, the transmitter emits optical beam through a fiber optic which in that case the beam remains spatially confined.

Massive amounts of data is sent and received over networks of fiber optic cables for various industries such as cable television, phones, and the internet. But if the wavelength of the isolated signal is changed before routing to the output port, then router is known wavelength converting router and in other case is wavelength routing switch optical switch in case of switching the wavelength to the complaint signal wavelength [29].

Usually, they are installed in a multi wavelength fiber span [7]. Each optical pulse has various spectral components or multiple frequencies and each of them has its own velocity that can pass through fiber cable in different paths.

Optical multiplexers are used to combine transmit optical signals that have different wavelengths into a composite signal which have boosts by optical amplifier if need to amplify before sending onto single optical amplifier.

Each of us is qualified to a high level in our area of expertise, and we can write you a fully researched, fully referenced complete original answer to your essay question. This first-generation system operated at a bit rate of 45 Mbps with repeater spacing of up to 10 km.

The information transmitted is typically digital information generated by computers, telephone systems, and cable television companies.

In past before EDFA deployment, individual wavelength through fiber had regenerated one time each 40 km long by using expensive electronic device and increased to km long when use more recent EDFA system [7].

All of this seems to be a very "modern" concept, and the technology we use is. Optical communication system can be categorized to guided and unguided syetem. A message may have to pass through multiple optical regenerators along its path. However dispersion problem can be lessen by decreasing the number of modes which can be reduced by diminishing the core radius, reducing numerical aperture, and increasing the light wavelength and that can be seen in the following equation: Physics yrs Animation, Video 4 You may have heard about fiber optics but the name itself does not say much about this fascinating technology.

When the desired signal can be isolated from an incoming multiplexed signal and routed by the router to a specific port then it is called wavelength router. Finally the ray of light, with the message imprinted on it, arrives at the optical receiver.

Optical amplifiers can be used by these lasers to amplify the signal strength to extend the transmission distance [24] [14]. Computers at the transmitting end convert data or voice into "bits" of information. Mode numbers decrease with decreasing fiber diameter and with a decreasing difference in refractive index between the fiber core and the surrounding area.

There is other network architecture based on three-layer as in figure 1. In the beginning offirst terrestrial optical system became available commercially with less than 0. The newest systems operate at more than two billion bits per second per fiber pair.

Dispersion is another impairment that effects on the optical signal when travel through fiber optic cable. So, all of the data is sent light pulses. During the s optical fiber technology is expected to extend to include both residential telephone and cable television service.

Bell South has been placing fiber cables in the Orlando area since the early s, and currently has hundreds of miles in service to business and residential customers.

History of Fiber Optics

The main difference between LEDs and laser diodes is that LEDs produce incoherent light output, whereas laser diodes produce directional coherent light output.

Optical Fiber Structure [10]. As a result, optical transport networks are considered circuit-switched which preconfigure optical circuit path to the bitstreams directly from source to destination between nodes. Using a semiconductor LASER or a light-emitting diode LED as the light source, a transmitter codes the audio or visual input into a series of light pulses, called bits.HOME Free Essays History of Fiber Optics.
