How to shove an elephant through a thread of copper or fiber-optic light that is the dilemma facing the managers of Siam Cement these days.
Corning (nyse: GLW - news - people), the fiber-optic firm, announced layoffs in its photonic devices unit, which makes devices that send light impulses over fiber-optic cables.
The light itself comes out of four LEDs that pass through a fiber optic glass designed to distribute the light evenly throughout the screen.
Perhaps most important, digital wireless is prying open the biggest bottleneck in tech--that "last mile" between speed-of-light fiber-optic networks and the zippy insides of your PC.
One company might own the fiber-optic cables, while another operates the light signals pulsing over that fiber, and a third owns (or more likely rents) the bandwidth encoded in that light.
Implicit in this vision is the Utopian fantasy that underlies most high-tech futurism: once Africa puts this infrastructure in place, all of its problems--tribalism, racism, poverty and disease--will disappear in the purifying light of a fiber optic cable.
When a pulse of light is sent into the tumor using fiber optic cable that is threaded into a tumor using a biopsy needle, the molecule absorbs the light energy, converts it electrical energy that then causes tumor cells to self destruct.
That information leaves the phone traveling as a light beam moving through fiber optic networks.
They are the fingers and eyes and noses of the computer, bringing the world (be it a car crash, pressure in a fuel line, or light in a fiber-optic network) into the boxed, insular space that sits quietly on desktops.
Some trading firms measure their competitiveness by the speed in which they can connect to financial exchanges and complete transactions, and even at the speed of light that data travels along the glass of fiber optic lines, locating even a few miles closer to the exchange could provide an edge.
The new single-laser fiber-optic speed record was set using a technique called fast Fourier transform that pulses light at an incredibly high rate with data encoded in 325 distinct colors across the spectrum.
Apple has embedded a fiber-optic lighting system to illuminate the keyboard and bolstered it with sensors that can tell when the ambient light in the room begins to dim.
