BACKGROUND OF FATHER OF FIBER OPTICS

• Charles Kuen. Kao, born on 4 November 1933
• Studied English and French in ShangHai
• Moved to HK in1948
• The residence in China,HK,UK and US
• Studied the environmental of the land reclamation

INVENTION PROCESS

• Raised a glass to send the message
• Studied in the glass matter
• Find a kind of glass which without impurity
• Discovered a quartz glass
• Invented pure optical glass fibers and glass fibers effectively

INVENTION PROCESS

• Take a long as its long-distance lines of communication
• 1981 , the first fiber optic system has finally arrived
• Dubbed the glorious title of " Father of Fiber Optics "

THE FUNCTION OF FIBER OPTICS

• Medium for telecommunication
• Computer networking
• Advantageous for long-distance communication
• Light propagates through the fiber with little attenuation compared
• Long distances to be spanned with few repeaters

THE HISTORY OF FIBER OPTICS

• 1870 John Tyndall discovered "electromagnetic wave"
• 1880 Alexander Graham Bell invented the telephone1870
• 1960 American physicist Theodore Harold Maiman Produce "laser."
• 1966, scientist Charles Kao discovered a quartz glass and invented fiber optic.
• 1977, USA developed the first grade Corning fiber optic reflectance

THE CHANGES/IMPROVEMENT OF FIBER OPTICS

• Used in endoscopy
• Used in audio,movies,video telephony, online gaming, etc.
• More convenient and widespread use of wireless networks
• Higher efficiency of network operations.
