    Optical fiber Optical fiber Presentation Transcript

    • JSS, K.H.KABBUR INSTITUTE OF ENGINEERINGTopic : Optical fibers By Nisarg Y Bhagavantanavar Brief Flow of the Presentation. 1. Introduction 2. What are Optical Fibers? 3. Structure of optical fiber 4. Workings 5. Advantages / Disadvantages of Optical fiber 6. Applications of 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? 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 fiberExtremely pure fused silica – very low loss for long distance transmissionCore – higher refractive indexCladding – lower Refractive indexBuffer coating – mechanical protection
    • Working of optical fiber Light Transmission
    • Advantages of optical fiber The optical fiber has following advantages over twisted -pair and coaxialcable.• Resistance to noise• Huge bandwidth• Higher signal carrying capacityDisadvantages Along with all disadvantages that it offers, optical fiber also has somedisadvantages, as summarized below.• Fragility• Cost• Maintenance overhead
    • 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• Reference:• Data communications and networks – by Achyuts godbole.• Digital communication – by K.Shashider.• Wikipedia – Internet. THANK YOU
