Brief Flow of the Presentation. Introduction What are Optical Fibers? Structure of optical fiber Workings Advantages / Disadvantages of Optical fiber Applications of Optical fiber JSS, K.H.KABBUR INSTITUTE OF ENGINEERING Topic : Optical fibers By Nisarg Y Bhagavantanavar

Optical fiber:

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?:

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:

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:

Working of optical fiber Light Transmission

Advantages of optical fiber :

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

Applications:

Applications Optical 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 :
