ʻO Aipu-waton GJYXCH a me GJYXFCH uwea optical he FTTH kakaka-ʻano hāʻule waho. Aia ka uwea optical 1 ~ 4 silica optical fibers me ka uhi, hiki iā G657A1 a i ʻole G652D. E hoʻohana ʻia nā fiber optical i hana ʻia e ka hoʻolālā like, nā mea a me nā kaʻina hana i loko o ka pūʻulu o nā huahana like, a e kau ʻia nā fibers optical i waenakonu o ke kaula optical. Hiki ke waihoʻoluʻu i ka papa uhi uhi fiber optical. ʻO ka waihoʻoluʻu o ka papa waihoʻoluʻu he uliuli, ʻalani, ʻōmaʻomaʻo, ʻeleʻele, hina, keʻokeʻo, ʻulaʻula, ʻeleʻele, melemele, poni, ʻulaʻula a cyan paha e like me GB 6995.2, a hiki i ka fiber hoʻokahi ke kala maoli.
