It is a lower cost alternative to using 100BASE-FX, because it uses short wavelength optics which are significantly less expensive than the long wavelength optics used in 100BASE-FX.
See on madalama hinnaga alternatiiv 100BASE-FX-le, sest see kasutab lühema lainepikkuse optikat, mis on palju odavam kui pika lainepikkusega optika, mida kasutatakse 100BASE-FX-is.
