ORGANIZATIONAL CULTURE

There are many desirable properties of optical fibers for carrying this information. They have enormous information-carrying capacity, are low cost, and possess immunity from the many disturbances that can afflict electrical wires and wireless communication links.

The superiority of optical fibers for carrying information from place to place is leading to their rapidly replacing older technologies. Optical fibers have played a key role in making possible the extraordinary growth in world-wide communications that has occurred in the last 25 years, and are vital in enabling the proliferating use of the Internet.

Of key importance in the course of these developments in information technology have been a few basic, but vitally significant, events.

Principal among these are the invention and development of the laser, the growing appreciation that this might make optical communications practically useful, the production of very pure glass, which was sufficiently transparent that long distance transmission of light through glass fibers became practical, and the digital revolution.

We will examine the role that each of these has played in creating the "Information Age.

This laser, which used a special ruby crystal, produced intense flashes of red light, a light with properties quite different from that emitted by conventional sources. A laser emits light in a very narrow beam— much like a searchlight.

Laser light is very spectrally pure -- it is of a very pure, well-defined color -- and is very bright. These properties make a laser ideal for shining light from place to place over long distances, and it was soon proposed that this provided new opportunities to expand the usefulness of optical communication links.

Over the last almost forty years, developments in the laser field have occurred at a rapid pace. Many new lasers have been discovered, each with its own special properties and applications, and their cost, performance, and practicality have all shown dramatic improvement.

Although the laser was first described as "a solution looking for a problem," this is no longer the case. These devices affect our lives in many ways, every day. At the supermarket checkout a laser illuminates the bar code on each purchase, allowing its rapid identification and pricing.

Every compact disk player contains a low-cost, semiconductor laser, whose beam illuminates the pattern of information encoded into the surface of the CD and allows its rapid re-translation into music or computer data.

The most widely used type of laser is the semiconductor laser, which has much in its technology in common with the semiconductor devices that we use in modern electronic devices.

The principal difference between these two semiconductor technologies is that conventional electronic semiconductors are almost exclusively based on the element silicon, whereas semiconductors used in lasers and related so-called optoelectronic devices are based primarily on mixed semiconductors made up from gallium Ga and arsenic Asand often aluminum Al as well.

Ancient man signalled with smoke and fire, often relaying messages from mountain top to mountain top. However, this optical communication scheme had limited transmission capacity.

They could serve as a warning, as Queen Elizabeth the First of England planned when she had a network of bonfires erected to be set in the event of a seaborne invasion from Spain. The smoke signals transmitted by native Americans had the capacity to transmit various messages. Since the end of the eighteenth century messages have been passed by semaphore — the use of flags to indicate the transmission of one letter at a time.

This form of communication could transmit information at a rate of about one letter per second over a direct line of sight, although messages could be relayed over long distances. Such means of communication were not very secure: The message could also be intercepted and altered during the relay process as the Count of Monte Cristo did to his advantage.

This technique was widely used by the US Cavalry in the desert south-west of the United States until the early part of the twentieth century. For optical communication to progress past these early efforts, an information carrying channel had to be developed that was reliable, inexpensive, and that could be used over long distances, preferably at high rates of data transmission.

The fundamental physical phenomenon that makes this possible is called total internal reflection. This phenomenon causes light to reflect, rather than refract, when it attempts to cross the boundary from one transparent optical medium to another of lower optical density, at a sufficiently large angle.

As early asin London, John Tyndall demonstrated that light could be guided inside a transparent medium with such a density discontinuity with its surroundings.

He did this by showing light being guided along a stream of water flowing from a container. His simple demonstration proves that in the right circumstances light need not travel in straight lines. This phenomenon is well known: The quantities n1 and n2 are the refractive indices of the media on opposite sides of the boundary.Fiber optics technology enables data, including voices captured in digital form, to be converted into tiny pulses of light and then transmitted at high speeds through glass fibers wrapped into large capacity telecommunication cables.

The Impact of Fibre Optics Technology Early Developments in Light Communication rapidly develop new advancements in technology.

Our proposed network will probably be based on Passive Optical Network (PON) technology. Current PON equipment is capable of speeds of around two gigabits per second (i.e. 20 times faster than the best consumer broadband technology available in the world today), and that remains the same whether it is deployed in Korea, Sweden or Australia. Impact Of Fibre Optics On Our Society. Fibre Optics Technology over the past century has advanced greatly. friends, or colleagues is how the economy is affecting our daily activities of living. Nanotechnology impacts our lives today in many ways, such as economically, socially, environmentally, ethically, and more. Nanotechnology is. Fibre optics is plastic material center that transmits digital impulses in the form of light pulses. That is a weakness for MTN because Globacom communications which is its great competition has begun implementing the use of fibre optics because of its communication.

The systems offer many advantages over the traditional metal (copper) wire form of fibre optics go well beyond the communication or data transmittance sectors. The fibre optic cable has. The consumption of such enormous chunks of data has led to recent advancements in cloud computing and Big Data-processing technology, resulting in a requirement for highcapacity networks.

Worldwide Internet traffic is about 1 Terabit per second, and could therefore, in principle, be carried on a single optical fiber. A typical optical fiber cable containing 8 distinct fibers will carry 8 Terabits per second, or 20 million Terabits per month. Today fiber optics are used by the Military, NASA, in the medical field, and more.

But did you know the first uses of fiber optics began in Roman times? The History of Fiber Optics.
