OPTICAL FIBERCAUSES FOR THE CREATION OF THE OPTICAL FIBER----- Man’s HUNGER Lastly optical fiber’s were invented to satisfy the Man’s hunger for communication
CONSTRUCTION OF OPTICAL FIBER Core Cladding Buffer coating
TOTAL INTERNAL REFLECTION When light travelling in an opticallydense medium hits a boundary at an anglelarger than the "critical angle" for themedia, the light will be completelyreflected. This is called total internalreflection. Fiber optic cables use total internalreflection inside the optical fiber.
ADVANTAGES Much higher bandwidth Thousands of channels can be multiplexed together over one strand of fiber Less expensive Higher carrying capacity Less signal degradation Light signals Digital signals Safety Non-flammable Lightweight Flexible
ADVANTAGES The optical fiber hasfollowing advantages overtwisted -pair and coaxialcable.• Resistance to noise• Huge bandwidth• Higher signal carryingcapacity
APPLICATIONS• Medical• Military• Electronics IBM microprocessors
