Glass purifying and fiber drawing techniques were fully developed by the year 1977

The light traveling in a strand of fiber-optic cable is prevented from escaping the fiber by total reflection.

Fiber optics was used in intercity applications by 1985.

Fiber optics was transoceanic by 1990.

A single glass fiber measuring .013 cm in diameter can replace 10,000 telephone wires.

Fiber optics greatest impact has been in the field of telecommunications.

L.E.D. stands for Light Emitting Diode.

Another name for stray electrical fields is interference.

Fiber optic glass fibers are made of ultrapure fused silica.

50 million of bits per second can travel along a fiber.

photo-diode detector amplifies, decodes, and regenerates the original information that travels along fiber.

Fiber optic cable can be used to help measure temperature, rotation, fluid flow, electric current.

Fields which uses fiber optic cable: imaging, robotics, surgical and dental.

An endoscope can view inacessible areas.

The auto and aviation areas use fiber optic cable to illuminate instrument panels.

In 1962, Bell Labs launched the Telstar satellite, the first that could transmit and receive signals.

Fiber optic systems needed less signal repeaters to correct for signal distortion than coaxial, didn't have the delay of
satellite transmission, and had a higher capacity than both.
