        We don’t. The measure is bits/s, which is a speed because it’s measured relative to time. 1 TB is a volume/amount, 1TB/s is a speed.

      Nope, if we are talking about the actual speed of the signal optical fiber is relatively slow at ~1/3 c, compared to air or copper where it’s almost c. They’re using ‘speed’ meaning bandwidth. A van full of sd cards would have a massive bandwidth, but a very slow actual speed

        Actually it’s about 2/3 c, the refractive index of normal telco fibers (G.652 and G.655) is around 1.47
