🌐 Japan breaks 1 petabit/second fiber speed record

Japanese engineers just pushed the limits of data transmission: over 1 petabit per second across 1,800 km of fiber — using cables compatible with today’s internet infrastructure.

  • That’s 10¹⁵ bits/sec — a quadrillion
  • Enough to stream the entire Netflix library in one second (allegedly)

  • Compatible with existing transmission systems
  • Reinforces that internet infra can handle surging global demand
