I have the same question. Why is Corning uses 80 mm fiber? From what I briefly read, the smaller size fiber actually allows faster communications over longer distances. "50 micron multimode fiber offers nearly three times more bandwidth (500 MHz·km) than FDDI-grade 62.5 micron fiber (160 MHz·km) at a wavelength of 850 nm [nanometers]." I assume this means 80 micron fiber would provide even less bandwidth.
