Optical amplifier could quadruple the range of fiber optic signals

As the amount of information being electronically shuttled around the planet continues to grow, so does the need for effective means of relaying it. The use of optical fibers has definitely helped in that regard, although thanks to a recent breakthrough at Sweden’s Chalmers University of Technology, optical fiber signals may soon be able to travel four times farther than they are presently able to. Researchers there have created an optical amplifier, capable of amplifying light while maintaining a relatively noise-free signal.
