4.  Optical communication systems date back
to the 1790s, to the optical semaphore
telegraph invented by French inventor
Claude Chappe.
 By 1970 Corning Glass invented fibre-optic
wire or "optical waveguide fibres" which
was capable of carrying 65,000 times more
information than copper wire.
 In April 1977,General Telephone and
Electronics tested and deployed the world's
first live telephone traffic through a fibre-
optic system running at 6 Mbps, in Long
Beach, California.
HISTORY

5.  SPEED: Fibre optic networks operate at high speeds -
up into the gigabits.
 BANDWIDTH: Large carrying capacity.
 DISTANCE: Signals can be transmitted further without
needing to be "refreshed" or strengthened.
 RESISTANCE: Greater resistance to electromagnetic
noise such as radios, motors or other nearby cables.
 MAINTENANCE: Fibre optic cables costs much less to
maintain.
