Fiber optic history essays for kids

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.

These types make use of an adapted semi-conductor laser. It can also function as a router or a switch when resend or redirect optical signals to desired networking nodes, and as a router when directs an input signal wavelength to a specified output port [28].

It is also used for imaging in hard to reach areas or places with extreme conditions such as deep underground, under the sea or inside the body. The diameter of the core dictates how much information can be sent and received at one time.

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]. Bell considered it his most important invention.

Fiber-optic Communication - History

During the s optical fiber technology is expected to extend to include both residential telephone and cable television service. The design of the laser systems should be: This difference also leads to what is known birefringence whereby a fiber with birefringence causes a propagating pulse to lose the balance between the polarization components.

Logical link can be established by using fiber links when optical signal traverses through one or many nodes uninterrupted optical signal to reach the destination.

Essay/Term paper: Fiber optics

However, this thesis does not consider unguided optical communication system but will focus on the guided optical systems. Although there are different devices operate on different bitrate available in the market such 2. Internal reflection can take place at any angle greater than the critical angle but optical light may not propagate through the fiber on all angles and that because some of incident angles result in destructive interference and that leads to prohibit light propagation, in contrast with other angles that cause constructive interferences which allows the light to propagate.

Third-generation fiber-optic systems operated at 1. Since glass is optically transparent, we are able to send information-laden rays of light over long distances.

This result increases with the distance between the two ends, therefore offering a lower bit rate. Low loss attenuation optical fibers together with optical so- urces led the efforts for enhancing the fiber-optic communication systems [6].

Moving up the hierarchy, metro-core tier aggregates the traffic from thousands of customers that relate to access networks and interconnects number of central offices of telecommunication or cable distribution head-end office by passing 10s tos of kilometers. Is named group velocity dispersion GVD and occurs in single mode type because of frequency dependence of the group velocity.

These channels were now apart at an interval of about GHz in the nm window.

Fiber Optics Essays (Examples)

Single mode and multimode fiber optic. A message may have to pass through multiple optical regenerators along its path. The term is used to refer to the technology where the energy of light is harnessed to transmit data, much like you would use an electric impulse in a copper wire.In this paper I will be telling you what a fiber optic cable is made of, how a fiber optic system works and a history of fiber optics from the 's to today.

Lets take a look at the optical fibers, what these fiber do is carry the light which is transmitted to the destination. Fun Facts About Fiber Internet Fiber-Optic Internet: How It Works and Why It's Important Fun Facts About Fiber Internet; Table of Contents. What is fiber optic Internet?
