ʻO ke kaula uila hoʻokahi- G.657A2 ʻO ke kaula uila hoʻokahi Fujikura
ʻOi aku ka maikaʻi o ke kūlou ʻana o ka Nanjing Wasin Fujikura o G.657A2 single mode fiber, hoʻohana nui ʻia ma ka pūnaewele FTTH. Hana ʻia e like me ke kūlana kiʻekiʻe loa, ʻoi aku ka maikaʻi o ka hana ma mua o ITU-T\GB/T9771 i ke kūlana hou loa. Hiki iā Wasin Fujikura ke hāʻawi i ke anawaena o 180um, 200um, 400um fiber, e ʻae ana i ke anawaena i hana ʻia e like me nā koi o ka mea kūʻai aku.
