  3. 3.  Optical communication systems date backto the 1790s, to the optical semaphoretelegraph invented by French inventorClaude Chappe. By 1970 Corning Glass invented fibre-opticwire or "optical waveguide fibres" whichwas capable of carrying 65,000 times moreinformation than copper wire. In April 1977,General Telephone andElectronics tested and deployed the worldsfirst live telephone traffic through a fibre-optic system running at 6 Mbps, in LongBeach, California.HISTORY
  4. 4.  SPEED: Fibre optic networks operate at high speeds -up into the gigabits. BANDWIDTH: Large carrying capacity. DISTANCE: Signals can be transmitted further withoutneeding to be "refreshed" or strengthened. RESISTANCE: Greater resistance to electromagneticnoise such as radios, motors or other nearby cables. MAINTENANCE: Fibre optic cables costs much less tomaintain.WHY FIBER OPTICS?
