E masani lava, e tolu ituaiga o uaea i luga o le ulu e tolu, GYFTY, GYFTS, GYFTA tolu ituaiga o uaea opitika, pe afai e le o le u'amea e aunoa ma se ofutau, o lona uiga o le GYFTY, o le lapisi milo le uamea e le o le uamea, e talafeagai mo mana, e fai ma ta'iala, e ta'ita'i i le uaea opitika. O le GYFTA o se fa'amaufa'ailoga e le fa'amalosia, alumini fa'aofuofu fiber optic cable. O le GYFTS ose fa'amalosi e le fa'ameamea, uaea fa'aofuofu uamea.
O le uaea opitika GYFTY e faʻaaogaina se fausaga milo faʻapipiʻi, ma o loʻo faʻapipiʻiina le alava mata i totonu o se paipa faʻapipiʻi e faia i mea polyester maualuga-modulus, ma faʻatumu le paipa i se mea e le susu. O le paipa matala (ma le maea faʻatumu) e milo faataamilo i se faʻamalosi totonugalemu e le o ni uʻamea (FRP) i totonu o se uaea faʻapipiʻi, ma o va i totonu o le uaea o loʻo faʻatumuina i le gaʻo poloka vai. Fa'alava polyethylene fa'alava i fafo o le uaea.
O le GYFTA opitika uaea faʻaaogaina se faʻapipiʻi faʻapipiʻiina. O le alava opitika o lo'o fa'apipi'iina i totonu o se fa'agaau fa'agasolo e faia i mea polyester maualuga-modulus, ma o lo'o fa'atumuina le fa'agaau i se mea e le susu. O le paipa matala (ma le maea faʻatumu) e milo faataamilo i se faʻamalosi totonugalemu e le o ni uʻamea (FRP) i totonu o se uaea faʻapipiʻi, ma o va i totonu o le uaea o loʻo faʻatumuina i le gaʻo poloka vai. O le ofutau alumini pito i fafo o le uaea autu o loʻo afifi umi, ona faʻapipiʻi lea o le polyethylene sheath. O le GYFTS o le fausaga tutusa e pei o le GYFTA, lea e suitulaga i le ofutau alumini faʻatasi ma faʻapipiʻi uʻamea lua.
E leai se mea uʻamea i totonu o le fausaga o le GYFTY, lea e talafeagai mo le uila, nofoaga maualuga eletise, ma nofoaga e iai le faʻalavelave faʻafefe eletise. E masani lava, GYFTA ma GYFTS uaea opitika e mafai foi ona faʻaogaina mo le eletise, i nofoaga e maualalo le siosiomaga. Non-metallic FRP faʻamalosia totonugalemu, faʻatinoga lelei faʻamalosi, uaea opitika anti-conductive Faiga o oloa: faʻamalosia e le faʻaogaina (FRP), talafeagai mo le uila, nofoaga maualuga-voltage, puipuiga uila; anti-faʻaloaloa, faʻafefeteina, faʻafefeteina, faʻafefe- Teʻi, e mafai ona faʻapipiʻi soo, mimilo, mimilo, punou (faʻapipiʻi tulimanu e le sili atu i le 90 °), fana, ma isi, faʻatasi ai ma mea faʻainisinia lelei; mautu le taamilosaga o le vevela, faaofuofu atoatoa, anti-seepage tafetafea, mumu mumu ma isi siosiomaga lelei Faatinoga; Sa'o pulea alava umi sili atu ma uaea stranding pitch mautinoa o le fiber optic uaea e sili ona lelei le faatinoga tensile ma uiga vevela; ole fa'amoemoe ole olaga e sili atu ile 30 tausaga. Mamafa mama, umi uaea laititi, ma uta laʻititi i luga o olo.
