Intel believes the days of using copper wires for data transfers, both between computers and inside of them, are numbered because optical communications are on the horizon.
The chipmaker has started shipping silicon photonics modules, which use light and lasers to speed up data transfers between computers.
The silicon photonics components will initially allow for optical communications between servers and data centers, stretching over long distances, said Diane Bryant, executive vice president and general manager of Intel's Data Center Group.
Over time, Intel will put optical communications at the chip level, Bryant said during a keynote at Intel Developer Forum on Wednesday. That means light will drive communications inside computers.
