Blistering data transmission record clocks over 1 petabit per second

Researchers in Japan have clocked a new speed record for data transmission – a blistering 1.02 petabits per second (Pb/s). Better yet, the breakthrough was achieved using optical fiber cables that should be compatible with existing infrastructure….
The new breakthrough is not only faster, but it only transmits data in one mode per core, meaning it can be read by technology already in wide use. To top it all off, the four-core optical fiber cable has the same 0.125-mm diameter as a standard cable, meaning it should be compatible with existing infrastructure and manufacturing processes.
