Researchers say they achieved fiber-optic data transfer speeds of 301 Tbps by using the E-band, a spectral band that has never been used in commercial systems  —  The researchers hit a rate of 301 terabits per second — equivalent to transferring 1,800 4K movies over the internet in one second — using existing fiber-optic cables.
