Laser Optic Fiber
It is reliable, it is fast, it is easier to maintain and it is one of the greatest engineering achievements of all time. Laser is recognized today as the high class and 7 star way of signals transmission.
Mostly because of its reliability, this highly sophisticated layer of fibers is used in many advanced telecommunications systems throughout the world. Because of its very high bandwidth and higher resistance to many environmental obstacles such as electromagnetic noises, laser can be used to transmit data to higher distances than with its counterpart copper wires. They do not require any amplifier or any other way of refreshing and re-grading the signals. Another prominent factor that keeps laser in a higher grade than the conventional way of networking is its higher speed. These attractive cables measure speed in gigabits per second.
Educational institutes, universities, television services providers and also cable services providers and many other industries that require a reliable and high quality networking are opting for a laser network.
In simple how laser work sounds very similar to all the other methods of
data transmission. It will have three major components namely the transmitter, data cable and the receiver. Transmitter will receive an electrical pulse of a signal and translate it to a light pulse. This light pulse will then be emitted by a light emitting diode or another method of light emission. Once the light pulse is received from the other end it will then be translated back in to an electrical pulse and be read by the receiver. In other words these laser are used to help electrical pulses be transferred at a much higher speed.
Because of the 100% reflection of the glass fibers in the core, these laser will almost wont waste any energy used for its purpose. This is where they will score more compared to copper wires where energy is wasted for heat as well.
However in todays world laser are only used in big industries and companies where it is essentially required and havent still been introduced for personal usage for homes and individuals mainly due to the higher cost in installation. But in times to come this could well be no more a problem with scientists finding newer ways of manufacturing this modern marvel of engineering.
