Frequency Combs Reverse Crosstalk, Extend Range of Fiber Transmission
SAN DIEGO, June 25, 2015 — Frequency combs could eliminate the need for repeaters, which are necessary for maintaining signals over long distances in today's fiber-optic networks. Developed at the University of California, San Diego, a patent-pending approach using frequency combs presents a potential solution to a long-standing roadblock to increasing fiber transmission rates: Beyond a threshold power level, additional power irreparably distorts the information. A wideband frequency comb ensures that...
