DSL Pioneer and Marconi Fellow, John Cioffi, Describes Terabit Future

By Rick Merritt

SAN JOSE, Calif. – At a time when carriers are pondering an expensive shift from copper cables to optical fibers, a pioneer of digital subscriber lines is proposing a novel upgrade that someday could deliver terabit data rates.

In a keynote at the G.fast Summit in Paris Tuesday (May 9), John Cioffi will unveil ideas behind what he calls Terabit DSL (TDSL). They include carrying 50-600 GHz wireless signals through the tiny spaces between individual twisted pairs or the cables that bundle a hundred of them.
