Fiber optic communication systems are light wave systems that employ optical fibers for transmitting information from one point to other through an optical fiber. The driving force behind the widespread use of fiber optic communications is the demand for economic, reliable transmission media that can transmit required information capacity. The transmission capacity of optical fibers has drastically improved over the years. Today, optical communications up to 100 gb/s for several kilometers have been introduced and research is still going on to enhance its capacity to terabits per second. This paper gives an overview of fiber optic communications – structure of optical fibers, different types of optical fibers, principle, fiber optic communications,

Communication is defined as the transmission of information from one place to another and there are two basic modes of communication; Broad casting and point-to-point communication. Broad casting involves use of a powerful transmitter and numerous receivers and information flows in one direction. In Point-to-point communications, communication takes place over a link between transmitter and receiver and in this mode of communication, flow of information is usually bidirectional. Information is often carried by an electromagnetic waves whose frequency varies from few meghahertz – several hundred terahertz and every communication system usually consist of three basic elements – transmitter, channel and receiver.
Information is communicated by converting it into electromagnetic signal and then transmitting it over a medium. Most commonly used transmission media include twisted -pair lines, optical fiber cable, terrestrial and satellite microwave. The field of fiber optic communications has exploded since its inception in 1980 and it has revolutionized the technology behind communications.

Core is the innermost section within very thin fibers made up of glass /plastic. Diameter of core ranges from 8 to 50 µm. Each fiber is surrounded by its own cladding – a glass/plastic coating containing optical properties with a diameter of 125 µm. Interface between core and cladding acts as a reflector and confines the light waves within that region. Jacket is the outermost layer that surrounds one or a bundle of cladded fibers and its composed of plastic and other material that protects the optical fibers from moisture, crushing, abrasion and any other damages.
Principle:
Principle behind optical fiber communication is internal reflection i.e.., light waves are reflected in such a way that it propagates down the core of fiber without leaving the material. When light enters between two materials of different indices of refraction, depending on the angle of entering light will either entirely get reflected or a portion of it gets refracted or bent. If the light is kept at an angle where its entirely reflected, it gets trapped inside core and cladding and gets transmitted down the length of
