Ua kapa ʻia ke kaula hoʻoheheʻe ʻo ke kaula hoʻoheheʻe ʻano kīʻaha kīʻaha (no ka wili o loko), ʻo ia ka mea e kau ai i ka ʻāpana kamaʻilio optical (fiber optika) i waenakonu, a kau i ʻelua mau lālā hoʻoikaika ʻole metala (FRP) a i ʻole nā lālā hoʻoikaika metala. ma na aoao elua. ʻO ka hope, hoʻokuʻu ʻia ʻeleʻele a keʻokeʻo paha , hina polyvinyl chloride (PVC) a i ʻole mea haʻahaʻa halogen-ʻole (LSZH, uahi haʻahaʻa, halogen-free, flame retardant) sheathed. ʻO ka uwea hāʻule waho i loaʻa i kahi uwea e kau ana iā ia iho ma ke ʻano kiʻi-8.
Hoʻokaʻawale ʻia ke kaula kulu i 1 core, 2 cores a me 4 cores single-mode fiber optic cable. ʻO ka maʻamau, hoʻohana ʻia kahi kumu hoʻokahi no ka lawe ʻana i ka ʻikepili home, a hoʻohana ʻia nā cores 2 no ka lekiō, televise, kelepona TV a me ka broadband.
ʻO ka hāʻule ʻana o ka uwea optical fibers maʻamau ka G657A2 fiber optical, G657A1 optical fibers, a me G652D optical fibers. ʻElua ʻano o nā mea hoʻoikaika kikowaena, nā mea hoʻoikaika metala a me nā mea hoʻoikaika FRP non-metallic. ʻO nā mea hoʻoikaika metala ʻo ① phosphating uea kila ② keleawe plated steel wire ③ galvanized steel wire ④ glued steel wire (me ka phosphated steel wire and galvanized steel wire with glue). Loaʻa i nā mea hoʻoikaika ʻole me ①GFRP②KFRP③QFRP.
He keʻokeʻo, ʻeleʻele, a hinahina ka puʻu o ke kaula kulu. Hoʻohana maʻamau ke keʻokeʻo i loko o ka hale, a hoʻohana ʻia ka ʻeleʻele ma waho, ʻo ia ka UV-pale a me ka ua. Aia i loko o ka waihona ka PVC polyvinyl chloride a me ka LSZH haʻahaʻa halogen-free flame retardant sheath material. ʻO ka mea maʻamau, hoʻokaʻawale nā mea hana i ka LSZH haʻahaʻa halogen-free flame retardant standard i ʻekolu ʻano: non-flame retardant, single vertical combustion flame retardant, a me ka puʻupuʻu ahi retardant.
Hiki i nā laina hoʻokuʻu ʻana i waho ke kākoʻo iā ia iho i 30-50 mika. Phosphating kila uea adopts 0.8-1.0MM, galvanized kila uwea, glued kila uea.
ʻO nā hiʻohiʻona o ke kaula hoʻoheheʻe: nā fiber optical kūwaho kūʻokoʻa, hāʻawi i ka bandwidth nui a hoʻonui i ka hana hoʻoili pūnaewele; ʻelua FRP a i ʻole nā mea hoʻoikaika metala e hana maikaʻi i ke kaula optical a pale i ka fiber optical; ʻO ka uwea optical he ʻano maʻalahi, ke kaumaha māmā, a me ka hoʻomaʻamaʻa ikaika; hoʻolālā groove kū hoʻokahi, maʻalahi e ʻili, pili pono, hoʻonohonoho maʻalahi a mālama; ʻO ka uahi haʻahaʻa halogen free flame retardant polyethylene sheath or flame retardant PVC sheath, pale kaiapuni. Hiki ke hoʻohālikelike ʻia me nā mea hoʻohui kahua like ʻole a hiki ke hoʻopau ʻia ke kahua.
Ma muli o kona palupalu a me ka māmā, hoʻohana nui ʻia ke kaula hāʻule i ka pūnaewele komo; ka inoa ʻepekema o ke kaula kulu: ʻano pepeke ke alakaʻi i loko o ke kelepona no ke komo pūnaewele; ma muli o kona ʻano pepeke, ua kapa ʻia ʻo ia ʻo butterfly cable, Figure 8 cable. Hoʻohana ʻia ka huahana i: hoʻohana ʻia no ka wili o loko, ke kaula pololei i hoʻohana ʻia e nā mea hoʻohana hope; hoʻohana ʻia no ka hoʻokomo ʻana i nā kaula optical i nā hale; hoʻohana ʻia no ka wili o loko o nā mea hoʻohana ma FTTH.
