In September 2009, Bell Labs set a new world record for data transmission. The research laboratory created an optical system capable of transmitting 100 petabits of data per second per kilometer (0.6 miles). One petabit is equal to one billion megabits. At that speed, you could transmit the data saved on 400 DVDs in just one second [source: PhysOrg]. In the future, everyone might be able to send and receive data at similar speeds.
