Muka Aratau Kotahi- G.657A2 Muka Aratau Kotahi Wasin Fujikura
He pai ake te piko o te muka aratau kotahi o Nanjing Wasin Fujikura o G.657A2, e whakamahia ana i roto i te whatunga FTTH. I hangaia kia rite ki te paerewa tino pai, he pai ake te mahi i te paerewa hou o ITU-T\GB/T9771. Ka taea e Wasin Fujikura te whakarato i te diameter o te muka 180um, 200um, 400um, e whakaae ana ki te diameter ritenga kia rite ki ngā hiahia o te kiritaki.
