A breakthrough technology will make the Internet fast and cheaper. Researchers have successfully raised the power and distance of sending optical signals over optical fibers. According to a report in The Economic Times of India on June 29, researchers at the Qualcomm Institute at the University of California San Diego have increased the transmission rate of optical fiber and cable data and made the Internet Fast, because fiber optic cable is the backbone of the Internet, wireless and wireline networks. Efforts by researchers to increase the fiber data rate have long been unsuccessful because excess power only distorts fiber optic cable transmission. Nikola Alic, a research fellow at Qualcomm Research, said today's fiber optic systems are a bit like quicksand, and beyond a certain limit, as More and more signals are in the fiber, the more serious the distortion is and can not be achieved Farther distance. "We took the approach of removing this power limit, and as a result the signals that are traveling through the fiber can be extended without the need for a repeater," he said. In laboratory experiments, when the signal was transmitted 12,000 km in fiber, researchers successfully deciphered the message by simply using a fiber optic cable and a general amplifier, without the use of a repeater, Electronic Regenerator. " This new discovery effectively removes the need for "electronic regeneration" that is periodically placed on fiber links. The breakthrough of the research lies in the broadband "Frequency Combs" developed by researchers. The frequency comb ensures that the "crosstalk" that distorts the signal is predicted and then transformed to be received at the end of the fiber. "Crosstalk" refers to the phenomenon of coupling between signals that interfere with each other. The researchers said: "We have come up with a way to use crosstalk to remove the power horsepower from the fiber." The study has been published in the internationally renowned academic journal Science.
