Fiber transmission range leaps to 2,500 miles, and capacity increases | Virtual Reality

transmission could be more efficient, go farther, carry more traffic and be cheaper to implement if the work of scientists in Sweden and Estonia is successful.

In a recent demonstration, researchers at Chalmers University of Technology, Sweden, and Tallinn University of Technology, Estonia, used new, ultra-low-noise amplifiers to increase the normal fiber-optic transmission link six-fold.

And in a separate experiment, researchers at DTU Fotonik, Technical University of Denmark used a unique frequency comb to push more than the total of all internet traffic down one solitary fiber link.

Fiber transmission limits

Signal noise and distortion have always been behind the limits to traditional (and pretty inefficient) fiber transmission. They’re the main reason data-send distance and capacity are restricted using the technology. Experts believe, however, that if the noise that’s found in the amplifiers used for gaining distance could be cleaned up and the signal distortion inherent in the fiber itself could be eliminated, fiber could become more efficient and less costly to implement.
