With the advent of fiber optic cables, and Googles plan to install fiber optic cables strait to the house holds of america; the need for a computer run on fiber optics, over the groggy copper wire is greater than ever. Luckily within the next few years computers with fiber optic cables will become available, read the story below:
Last week, Paniccia’s team demonstrated the first complete photonic communications system made from components fully integrated into silicon chips. Electronic data piped into one chip is converted into laser light that travels down an optical fiber and is transferred back into electrical signals a few fractions of a second later. The system can carry data at a rate of 50 gigabytes per second, enough to transfer a full-length HD movie in less than a second.
The silicon photonic chips could replace the electronic connections between a computer’s key components, such as its processors and memory. Copper wiring used today can carry data signals at little more than 10 gigabytes per second. That means critical components like the central processing unit and the memory in a server cannot be too far apart, which restricts how computers can be built.
The new Intel setup has four lasers built into its transmitter chip that shine data into a single optical fiber at slightly different wavelengths, or “colors.” Chips with even more lasers should make it possible to communicate at 1,000 gigabytes per second.
