About Petabits per second

Petabit per second (Pbit/s) = 10¹⁵ bit/s (SI). Research-scale only: NTT (2024) achieved 1.53 Pbit/s over a single fibre using space + wavelength division multiplexing. The combined peak of the world's largest internet exchange points (DE-CIX, AMS-IX) is multi-Tbit/s. Global IP traffic ≈ 1.8 Pbit/s sustained average in 2030 forecast. 1 Pbit/s = 10¹⁵ bit/s = 125 TB/s.

About Kilobytes per second

Kilobyte per second (KB/s) = 1,000 B/s = 8,000 bit/s (SI). Legacy modem throughput: 56 kbit/s dial-up ≈ 7 KB/s; ISDN 128 kbit/s = 16 KB/s. RS-232 at 115,200 baud (8N1) = 11.52 KB/s. CD-ROM 1× = 150 KB/s; 52× = 7,800 KB/s. Bluetooth 2.1 EDR ≈ 300 KB/s; USB 1.1 Full Speed = 1,500 KB/s. 1 KB/s = 1,000 B/s = 8 kbit/s.
