      Ukuhlaziywa okuningiliziwe kwe-EPON vs GPON yikuphi okungcono?

      I-EPON ne-GPON banokufaneleka kwabo. Kusukela kunkomba yokusebenza, i-GPON iphakeme kune-EPON, kodwa i-EPON inezinzuzo zesikhathi nezindleko. I-GPON iyabamba. Uma sibheke phambili emakethe yokufinyelela ye-broadband yesikhathi esizayo, kungase kungabi ukuthi ubani othatha indawo kabani, kufanele kuhlalisane futhi kuhambisane. Okwe-bandw...
