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
Cool information, thanks!
