optical fiber speed record
Isn't that simply the speed of light, always? ;-)
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!
It is pretty confusing that we refer to the volume of data as speed in networks.
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.
