INTRODUCTION
The use of light for the transmission ofinformation 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 toconventional copper wire in a variety of
applications such as those associated withsecurity, telecommunications, instrumentationand control, broadcast or audio/visual systems.

OPTICAL COMPUTING
An optical computer is a device that uses visiblelight or infrared beams, rather than electriccurrent, to perform digital computations.
Optical computers promise speeds, which will bethousands, even millions of times faster thanthose of today's most efficient supercomputers.
The optical computer could revolutionizecomputing in much the same way that thesemiconductor chip revolutionized electronics 30
years ago.An electric current flows at only about 10 percentof 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 opticalconnectors - by the family or type of connector,and by the type of end finish that they have.
Main types of connectors include
1. Epoxy & polish2.preloaded epoxy or no-epoxy & polish
3. No-epoxy & no-polish
