“ FIBER OPTICS BASED COMPUTER NETWORK”

INTRODUCTION The use of light for the transmission of information is far from a new idea. Fiber optics is a relatively new technology that uses rays of light to send information over hair- thin fibers at blinding speeds. These fibers are used as an alternative to conventional copper wire in a variety of applications such as those associated with security, telecommunications, instrumentation and control, broadcast or audio/visual systems.

WHAT IS AN OPTICAL FIBER An optical fiber is a wave guide for light consists of : coreinner part where wave propagates cladding outer part used to keep wave in core bufferprotective coating jacketouter protective shield can have a connector too

ADVANTAGES OF OPTICAL FIBER Small Size Light Weight High Bandwidth No Short Circuits Fewer Repeaters Noise Immunity Transmission Security

OPTICAL COMPUTING An optical computer is a device that uses visible light or infrared beams, rather than electric current, to perform digital computations. Optical computers promise speeds, which will be thousands, even millions of times faster than those of today's most efficient supercomputers. The optical computer could revolutionize computing in much the same way that the semiconductor chip revolutionized electronics 30 years ago. An electric current flows at only about 10 percent of the speed of light.

BRIEF IDEA ABOUT CONNECTORS Connectors are used to join two fibers together, or to connect a fiber to a piece of equipment There are two main ways of describing optical connectors - by the family or type of connector, and by the type of end finish that they have. Main types of connectors include 1.Epoxy & polish 2. Pre-loaded epoxy or no-epoxy & polish 3. No-epoxy & no-polish

CONNECTOR CLEANING Connector damage can occur if foreign particles are caught in the end face area of mated connectors. Connector cleaning is simply completed by wiping the connector ferrule and end face with some isopropyl alcohol and a lint free tissue. Another option for connector cleaning is the cassette type cleaners which use a dry tape system where the tape is advanced every time the cassette is opened ensuring the clean section of tape is used each time.

CONCLUSION The applications of the fiber optics field are still emerging and developing so rapidly that, it is impossible to keep track each and every innovations and inventions. All the above compilations gives idea about the tremendous potential associated with this field. The future is not so distant when scientists and researchers will come up with more and more futuristic products and applications using optical fibers.
