How Does Fiber Optics Trasmit Messages With Light
Fiber optics are widely used in fiber optic telecommunication systems which allows the transmission of data over longer distances since it carries a higher bandwidth to homes and offices. The information is sent through thread-like glass fibers using ultra-fast pulses of light. Although fibers can be made out of transparent plastic, glass, or a combination of the two, the fiber used in long-distance telecommunications applications are always glass, because of the lower optical attenuation.
Cable TV shows, phone calls, or Internet files normally travel through copper wire cables in the form of electrical signals. But in a fiber optic system, a transmitter converts these electrical signals into pulses of light which travel along the length of the fiber optic cable until they reach the end of the line. The receiving end then re-converts the light pulses to electrical signals to turn them back into voice, video, and data files.
But how does an ultra-thin thread of glass hold so much information? Unlike ordinary glass which is not pure enough to permit light to travel very far, fiber optic glass is so pure that almost nothing deforms the light pulses traveling down its length. So, fiber optic technology can carry so much information for very long distances - 60 miles or more - before the light signals have to be boosted.
Fiber optics is particularly created to keep the light signals from being lost out of the fiber by including a layer of a different material around the inner core of pure glass. Called the cladding, this layer, mirrors the light back toward the center and prevents it from [escaping]. Further layers of coatings shield the fiber frombends, cracks, etc. that could weaken the light signals.
The light pulses have to be strong enough and keep their shape long enough so that they don't lose too much data while the travel along the path to transfer data through fiber optics. Through fiber optic light sources, that are laser diodes and light-emitting diodes, or LEDs, this is feasible.
The laser diodes utilized in fiber optic technology are like the ones used in CD and DVD players. Lasers send out coherent light, meaning all the light particles, or photons, have exactly the same wavelength. Clear light pulses keep their shape longer, which means they can work at quicker data speeds with less information loss. Moreover, laser diodes keep the signal traveling farther before it loses strength. However, LEDs are less powerful than lasers but cheaper to make. For short-distance fiber optic networks, they work well enough.
Fiber optic telecommunication systems promise clearer phone calls, faster Internet connections, and many more standard and HDTV cable channels. Currently, a number of multinational companies have transformed their communication infrastructure to fiber optics. It's high time that you do too. Whether you need a gigabit converter or SFP transceiver for your networks, just make sure they come from a reputable fiber optics provider.
cam corder question dvd transfer?
i have some movies i would like to put on to disk but dont know which ones to use the videos are recorded on to a mini disk in the camcorder wich is -r so do i get the same dvds to transfer to or do i get +rw
It doesn't matter - whatever your DVD player can handle is fine. Most modern players are very tolerant but if you have a cheap supermarket player it'll probably play anything! I know that sounds counterintuitive, but the cheaper players use generic PC components and ignore the DVD standards.

# The Charge
Madame Anais: "I have an idea. Would you like to be called 'Belle de Jour'
(Beauty by day)?"
Severine Serizy: "Belle de Jour?"
Madame Anais: "Since you only come in the afternoons."
Severine Serizy: "If you wish."
# Opening Statement
**Belle de Jour** is a 1967 masterpiece from surrealist artist Luis Buñuel
that looms large in film history as a sexy, off-kilter, iconic work. It stars
a very young Catherine Deneuve (**The Hunger**) embodying a frigid housewife
who becomes a prostitute only during the day. She's the picture perfect
dutiful wife by night, and a scandalous woman of ill repute in the broad
daylight. The basis for the story came from a popular 1928 novel by French
author Joseph Kessel, but Buñuel found a way to insert his own stamp on the
proceedings by creating erotic fantasy sequences that explain the housewife's
inner life. Buñuel took a linear narrative and spruced it up with vivid dreams
that turned the lead character's world inside out. It is the director's most
celebrated work, and one of the best roles for one of France's most
recognizable stars.
