OPTICAL FIBERS
Optical fi bers carry a dizzying amount of data each second, but a great deal of communication still gets beamed, via slower microwaves, from one dish antenna to another. Engineers didn’t think there was any improvement to tease out of this technology, but researchers at the University of Paris recently reported in the journal Science that they’d found a way of focusing microwaves into a narrow beam, tripling the data rate.
