Copper vs. Fiber Modern telecommunication networks rely primarily on two types of cable. Older copper cables have been replaced in many cases by fiber optic "light pipes‚" first in undersea cables and major intercity trunks‚ and later directly to many homes and businesses. Principles Copper cables carry information as an electrical signal‚ which may be digital‚ as in phone lines‚ or analogue‚ as in audio speaker cable. In optical fibers‚ however‚ data is carried digitally by light from a laser

there have been numerous inventions and discoveries. The latest one has been that of Fiber optic cables‚ which have gained more respect in the market than the copper cables. These cables are widely used in offices or residential areas. Copper cables transmit information through electrical signals. It has been used as a speaker system wire‚ telephone wire‚ computer cable wire etc. for over years now. Optical fiber comprises of plastic or glass strands to transmit data or information digitally with

What I have read about face the fats sections it has talked about the healthy andf the healthy fats for example the trans fats are junk food and the unhealthy things that we eat and the fats that have been blamed for. One of them are weight gian or clogged arteries and so on forth. On the other hand there are good fats for example monounsatutated fats‚ or even polyunsatutated Fats‚ lets not forget the omega-3 which has the effect of the opposite. Did you know that‚ the healthy fats that is in our

Highlighting the strands of hair can be acquired naturally or chemically. To change the hair naturally‚ sunlight can brighten the hair depending on the color. This process takes a couple of weeks to notice a change in the color of the hair. Those with darker hair such as medium brown tend to turn to hydrogen peroxide or a hair lightener cream. When using these chemicals the artificial color pigments is removed from the hair strands‚ this is referred to as “stripping.” To fully understand the process

Influences of Fiber Optics Introduction: People have been trying to improve communications over the centuries. Communication plays a very important role in everyday life. The advancement of the world mostly depends on how we share the information with the rest of the world. Fiber optics is making this task easier and quicker. It is currently the fastest internet technology. Fiber optic is a technology of transmitting light through very thin flexible glass or plastic fibers. It is one of the fastest

HISTORY OF FIBER OPTICS * In 1840‚ Daniel Colladon and Jacques Babinet demonstrated the principle of guiding light by refraction. * It was followed by a public demonstration by John Tyndal in 1852. In 1870‚ Tyndal wrote about the property of total internal reflection in his book about the nature of light. * In 1880‚ Alexander Graham Bell and Sumner Tainter invented the Photophone‚ a device capable of transmitting sound waves over beam of light. This is considered as mankind’s first attempt

Trace Evidence Trace evidence is an important part of a team in solving crimes in forensic investigations. According to Edmond Locard‚ there is specific that no matter wherever people interact with their environment or is physically involved in a crime often leaves something at or something away from the scene. Those in this category of evidence include many diverse types of macroscopic or microscopic materials that certain examples are easily visible to our “naked eye”. The subject is broad and
