Advantages And Disadvantages Of Optical Fiber Communication

The medium comes in the form of a salvific complex of fiber optic cable and ROM,

Fiber: A fiber cable is either multiple strands of fiber optic surrounded by insulation, or a single fiber strand surrounded by insulation.

The base of the light triangle, b, was measured first. Then, the light positions, a, were measured f=or the first order (m=1) and second order (m=2) light beams to determine the angle Ɵ for each. This data was organized in an Excel table and used to find the wavelength, λ, of the laser through Equation 1. This value was then compared to the theoretical value for wavelength of the laser, which was 6.328x〖10〗^(-7)m, and the percent error was calculated between the two.

1. In your opinion, what is the purpose of our dropping the transmit power to such a low level?

Attenuation misfortune can be as low as 0.2 dB/km in optical fiber cables, permitting transmission over long distances without the requirement for repeaters.

Lasers can accomplish lithotripsy by having a photoacoustical/photomechanical effect (laser-induced shockwave lithotripsy) or a predominantly photothermal effect. Laser beams have a number of other useful functions, for instance, the production of compact discs (CDs). Lasers etch information onto a surface, and because of the light beam's qualities, can record far more information in much less space than the old-fashioned ways of producing phonograph records. Before the advent of fiber-optic communications, telephone calls were relayed on thick bundles of copper wire; with the appearance of this new technology, a glass wire no thicker than a human hair now carries thousands of conversations.

In order to operate in the fundamental 10 TM mode, the length of the patch must be slightly less than λ / 2 where λ is the wavelength in the dielectric medium and is equal to λ0 / ε ff where λ is the free space wavelength. The 10 TM modes implies that the field varies one

For the lowest temperature, 3°C, we used ice. The highest light transmission is 97% and the lowest is 77%. This large range could be because as th experiment went on the temperature of the ice increased.

Use tools and materials to design and build a device that uses light or sound to solve the problem of communicating over a distance.* [Clarification Statement: Examples of devices could include a light source to send signals, paper cup and string “telephones,” and a pattern of drum beats.] [Assessment Boundary: Assessment does not include technological details for how communication devices work.]

Laser technology has proven to be very useful and widely needed. In the 1950’s scientists began looking for a way to have a coherent light source unlike candle lights and lamp lights that are brighter towards the source and dims out when it’s farther away. After a few years, lasers were created. They all have the same wavelength therefore they can travel a larger distance. Sixty years later, lasers have become important in scientific research, industry, medicine, and

Fiber Lasers were invented in 1963 and since the 1990's they have been advanced almost entirely by IPG Photonics Company. The fiber lasers are compact and can be rolled in coils and take in sunlight which increases its brightness and power by over 30%. This fiber laser is twice as strong as the solid state lasers (Extance). The High Energy Laser Mobile Demonstrator is a prototype mechanism that is placed in top of camouflaged trucks and shoots an invisible infrared laser at the enemy planes or weapons. Inside the truck an engineer sits in front of a computer and aims and shoots the invisible laser at the enemy. This laser is one of the best forms of defense because it only takes two cups of fuel and an outside energy source such as a generator, whereas a conventional inexpensive missile costs around 100,00 dollars per shot (Extance). The fiber laser only costs less than 10 dollars per shot. This makes the fiber lasers a very effective line of defense against flying targets. Other prototypes such as the LaWS laser systems have been designed to be placed on United States boats and are able to target smaller enemy boats. Direct Energy weapons use lasers and microwaves as a weapon. Although not many of these weapons

In 1960 a breakthrough came forth. The invention of the laser had pure and intense light that was well suited for the making of holograms. Emmett Leith and Juris Upatnieks

One of the most interesting developments in recent years in the field of telecommunication is the use of laser light to carry information over large distances. It has been proved in

Light enters one end of the fiber from a light bulb, laser, or some other source, and travels essentially unimpeded all the way to the length of the fiber where it is intercepted by a photosensitive detector such as an electronic device or even the human eye. The distance of travel varies according to the use to anywhere from just a few inches to over one-hundred and fifty miles. Fiber optic cable can transmit large amounts of information over one-hundred and fifty miles almost instantaneously. “While it takes five hours to transmit the contents of an encyclopedia over copper wires, the entire work can be transmitted in less than a minute over fiber optics” (Yawn PG).
