Abstract:
Communication is the basic need of humans. First they had used signals of fire, smoke as transmission mediums to transfer information or to communicate with each others, but with. the passage of time the communication medium improved and becomes more reliable and faster, now a days we have many mediums for transferring the information and for communication like satellite, microwaves, fibers and many more. Emphasizes in this report has been on fiber optics, Fiber optics uses light to send information (data). More formally, fiber optics is the branch of optical technology concerned with the transmission of radiant power (light energy) through fibers. Fiber-optic communications is based on the principle that light in a glass medium can carry more information over longer distances than electrical signals can carry in a copper or coaxial medium. The purity of today's glass fiber, combined with improved system electronics, enables fiber to transmit digitized light signals well beyond 100 km ( 60 miles) without amplification. With few transmission losses, low interference, and high bandwidth potential, optical fiber is an almost ideal transmission medium. In this report effort has been made to discuss all the areas related to the fiber optic, from its basic concepts to it~ manufactures moor pa·ocia~oly memento\touring of fiber optics in Pakistan. Fiber optics manufacturing is a very high technology industry and Pakistan is a developing country, but it's pleasing to hear that Pakistan is manufacturing fiber and fiber optics cable.
