History Need OFC Layers Types Principle Parameters Transmission Splicing Applications
CONTENTS
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
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.
