One of the most interesting developments in telecommunication is the rapid progress of optical communication where optical fibers are replacing conventional telephone wires and cables. Just as digital technologies greatly improved the telephone system, optical communication promises a considerable increase in capacity, quality, performance and reliability of the global telecommunication network. New technologies such as optical fibers will increase the speed of telecommunication and provide new, specialized information service. Voice, computer data, even video images, will be increasingly integrated into a single
digital communication network capable to process and transmit virtually any kind of information.
The advent of the laser in the early 1960 set in motion a train of events that is steadily changing the outlook for optical communication. The past few years have been made three important advances. One was the invention of the semiconductor-diode laser, which satisfied the need for a cheap, efficient and long-lived source of coherent light waves to serve as the carrier waves for encoded signals. Another noteworthy advance was the development of ultra-thin, low-loss optical fibers, which are well suited for the long-range transmission of light waves, and, finally, an entire new generation of compact optical devices based on the precise guiding of laser light is being devised. Two technologies were combined: the laser, first demonstrated in 1960, and the fabrication 10 years later of ultra-thin silicon fibers which can serve as light wave conductors. With the further development of very efficient lasers plus continually improved techniques to produce thin silica fibers of incredible transparency, optical systems can transmit pulses of light as far as 135 kilometers without the need for amplification or regeneration.
At present high-capacity optical transmission systems are being installed between many major cities at a rapid rate. This system has a number of basic constituents. First, there must be an oscillator of some kind to generate the “carrier waves “in a highly coherent form (that is, with the all in step at the same frequency). Next, the waves must be modulated to carry information by varying either their frequency or their amplitude. The modulated microwave beam is then transmitted either by channeling it through a metallic waveguide or by propagating it through the atmosphere. The system most widely used now operates at 147 megabits (thousand bits) per second and accommodates 6 000 circuits over a single pair of glass fibers (one for each direction of transmission). This system will soon be improved to operate at 1.7 gigabits (thousand million bits) per second and handle 24 000 telephone channels simultaneously.
A revolution in information storage is underway with optical disk technology. The first optical disks appeared in the early 1970-s. They were and are used to record video films, but in a continuous spiral rather than digitally. The first digital optical disks were produced in 1982 as compact disks for music. They were further developed as a storage medium for computers. The disks are made of plastics coated with aluminium. The information is recorded by using a powerful laser to imprint bubbles on the surface of the disk. A less powerful laser reads back
the pictures, sound or information. An optical disk is almost indestructible and can store about 1 000 times more information than a plastic disk of the same sizе.
The latest optical disk development is a system which enables computer users to record their own information on a glass or plastic disk coated with a thin film of tellurium. Such a disk can store 200 megabytes (200 million characters).Besides, it is reported that an optical equivalent of a transistor has been produced and intensive research on optical electronic computers is under way at a number of US companies as well as in countries around the world. It is found that optical technology is cost-effective and versatile. It finds new application every day – from connecting communication equipment or computers within the same building or room to long distance transcontinental, transoceanic and space communications.
