AT&T; Bell Labs Sets Laser Pulse Record

MURRAY HILL, N.J. —
AT&T; Bell Laboratories has claimed a laser “traffic flow” record.
The laboratory’s scientists have designed a laser that generates 350 billion light pulses per second, each pulse lasting less than a trillionth of a second. That is the highest number of laser-generated light pulses ever to flow over a fiber optic cable.
The fastest commercial light-wave systems send light signals down a fiber optic cable at a rate of 2.5 billion pulses a second.
Telephone systems use lasers to send voice and data communication over glass fiber cables.
