About Petabits

A petabit (Pbit) = 10¹⁵ bits (SI). Major internet exchange points (DE-CIX, AMS-IX) handle peak traffic of multi-Tbit/s, accumulating Pbits per hour. Bell Labs (2022) achieved 1.02 Pbit/s over a single fibre pair. CERN LHC distributes ≈ 720 Pbit/year through the WLCG computing grid. 100 wavelengths at 800 Gbit/s each = 80 Tbit/s per fibre; ≈13 such fibres = 1 Pbit/s. 1 Pbit = 10¹⁵ bits = 125 TB.

About Petabytes

A petabyte (PB) = 10¹⁵ bytes (SI). Major platforms operate at PB scale: Meta ingests > 4 PB/day; YouTube adds several PB of video content daily. CERN Run 3 produced ≈ 90 PB in 2022. 1,000-genome cohort (WGS at 30×) ≈ 0.4 PB. English Wikipedia with media ≈ 10 PB. A rack of Blu-ray cold storage (Facebook Project Amber) holds 1 PB. 1 PB = 10¹⁵ bytes = 1,000 TB.
