Fiber Optic

Fiber Optic Technology.

 Today we talking about fiber optic..  Have Fun...

-- A fiber-optic system is similar to the copper wire system that fiber-optics is 
    replacing.

-- Difference – fiber-optics use light pulses to transmit information down fiber 
    lines(electronic pulses in copper lines).

-- There are generally five elements that make up the construction of a fiber-
    opticstrand, or cable:

1. the optic core

2.optic cladding,

3. a buffer material,

4.a strength material 

5.the outer jacket

--  The International standard for the cladding diameter of optical fibers is 125 
     microns (um).

--  The compatibility is important - it allows fibers to fit into standard connectors 
     and splices, and allows standard tools to be used throughout the industry.

--  The differences among fibers lie in their core sizes – the light carrying region
     of the fiber.

--  Standard Single-Mode fibers – are manufactured with the smallest core size, 

     approximately 8­10 um in diameter. 

--  With its greater information-carrying capacity,

 -- Single­mode fiber typically is used for :-

•           longer distance and
•           higher bandwidth applications.     

  -- Multi-Mode fibers are available in several core sizes

       - The most widely used sizes are 50 um and 62.5 um. Larger core sizes generally have greater bandwidth and are easier to couple and interconnect.

Picture show the sizes single mode and multimode.
