INTRODUCTION
Fiber Optic technology is simply the use of light to transmit the data
The general use of fiber optics did not begin until the 1970s
Robert Maurer developed a fiber with a loss of 20 dB / km
Since that time the use of fiber optics has increased drastically
What is Fiber optics ?
Transmitting communication signals over hair thin strands of glass or optics
Fiber Optics Overview
Telephone companies initially used fiber to transport high volumes of voice traffic.
During the 1980s telephone companies began to deploy fiber throughout their networks.
Applications
IN SENSOR SYSTEMS
In sensing a physical parameter, a fiber itself acts as a modulator in response to influences
with the help of fiber we can measure temperature , stress , strain displacement etc..,
CHEMICAL MEASUREMENT
Measurement of chemicals and or component species of chemicals is usually done in laboratories using mass spectrometer , gas chromatographs , IR and NMR spectrometers etc..
In the case of hydrocarbons , fiber optic wire is being used to monitor buried tanks ,lines and structures for leakage in to the surrounding soil.
The sensor comprises of a fiber optic cable and Optical Time Domain Reflectometer (OTDR).
The OTDR measures the distribution of optical power loss with distance along the entire length of the cable up to a maximum of 2.5 km.
Hydrocarbons in contact with the cable induce a local power loss
