but not only that, but you'll put not just one wavelength of light through one of the fibers, but you'll put maybe 50 or 60 or 70 different wavelengths or colors of light through a single fiber, and then you'll have maybe eight fibers in a cable, four going in each direction.
Mai mult de atât, nu-i doar o lungime de undă a luminii ce trece printr-o fibră, ci poate 50, 60 sau 70 lungimi de undă sau culori de lumină printr-o singură fibră și, poate, opt fibre într-un cablu, câte patru în fiecare direcție.
