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

Particularly‚ optical fiber communication plays a vital role in the development of high quality and high-speed telecommunication systems. Today‚ optical fibers are not only used in telecommunication links but also used in the Internet and Local area networks (LAN) to achieve high signaling rates. What is fiber optic communication? Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. The light forms an electromagnetic

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

Carbohydrates have two major functions in plants and animals: they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose‚ and since glucose is a major cellular fuel‚ starch represents stored energy. The sugar can later be withdrawn by hydrolysis‚ which breaks the bonds between monomers. Animals‚ in turn‚ have enzymes that

Synthetic Fibers Industry Synthetic fibers are the result of extensive research by scientists to improve on naturally occurring animal and plant fibers. In general‚ syntheticfibers are created by forcing‚ usually through extrusion‚ fiber forming materials through holes (called spinnerets) into the air‚ forming a thread. Before synthetic fibers were developed‚ artificially manufactured fibers were made from cellulose‚ which comes from plants. These fibers are called cellulose fibers. Raw materials:

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

Understanding the functions of the body systems associated with energy metabolism Energy is used for many of the bodily functions including the ability to ventilate‚ respire‚ move‚ grow and repair. The first law of thermo dynamics states that energy can be transformed from one state to another but cannot be lost. Energy comes in many forms‚ some of these are as follows:- Light Sound Kinetic Heat Chemical In accordance with the First Law an example of how energy can transform is when the sun creates

Understand Your Fats and Fibers Name here teacher SCI/241 Date here Understand Your Fats and Fibers According to “Face the Fats” (2013)‚ the unhealthy fats are‚ saturated and trans fats‚ tend to be more solid at room temperature (like a stick of butter). The healthy fats are monounsaturated and polyunsaturated fats and they tend to be more liquid (like liquid vegetable oil). Saturated fat is found mostly in foods from animals and some plants. Polyunsaturated and monounsaturated fats are
