Fiber Optics – Physics Research Assignment by Nathan S
Fiber optics is a technology that uses glass fibers to transmit data. A fiber optic cable consists of a bundle of glass threads each which is capable of transmitting messages modulated into light waves. ...
Examining a fibre optic cable more closely u can find three parts:
the core: the thin glass centre of the fiber where the light travels. ...
the buffer coating: Plastic coating that protects the fiber from damage and moisture
and all of these insides are protected by the cables outer covering, called a jacket.
Fiber optic cable transmits data in a different way. ... The core of fiber optic wire, its thin, glass centre is lined with mirrors that will reflect light around corners and keep it moving onwards.
The light in a fiber-optic cable travels through the core by constantly bouncing from the cladding (mirror-lined walls), a principle called total internal reflection. ... Still, some of the light signal degrades within the fiber, mostly because of impurities in the glass. ...
The Transmitting process
Transmitter - Produces and encodes the light signals
Optical fiber - Conducts the light signals over a distance
Optical regenerator - May be necessary to boost the light signal over long distances
Optical receiver - Receives and decodes the light signals
The first attempts at guiding light on the basis of total internal reflection in a medium dates to 1841 by Daniel Colladon.
