Optical fiber
INTRODUCTION
CAUSES FOR THE CREATION OF THE OPTICAL FIBER----- Man’s HUNGER
Smoke Horse riders Telephone & Telegraph that used copper wire
Coaxial cable VHF and UHF Radios, Satellite still UNSTISFIED .
Lastly optical fiber’s were invented to satisfy the Man’s hunger for communication
What are optical fibers?
Fiber optics = Fiber + optics
in essence = Light is guided in optical fiber.
Fiber = Extremely pure glass(silica) or plastic
Speed= current record
15.5tbps
Total internal reflection
Structure of optical fiber
Extremely pure fused silica – very low loss for long distance transmission
Core – higher refractive index
Cladding – lower Refractive index
Buffer coating – mechanical protection
Working of optical fiber
Light Transmission
Advantages of optical fiber
The optical fiber has following advantages over twisted -pair and coaxial cable.
• Resistance to noise
• Huge bandwidth
• Higher signal carrying capacity
Along with all disadvantages that it offers, optical fiber also has some disadvantages, as summarized below.
• Fragility
• Cost
• Maintenance overhead
Disadvantages
ApplicationsOptical fiber have wider range of application in almost all field, i.e. in medical, electronics, military etc .some are been specified below
• Medical
• Military
• Electronics
IBM microprocessors
• Conclusion: This is the greatest discovery that man have done in the field of communication
