Ngokuvamile, kunezinhlobo ezintathu zeizintambo ezingezona ezensimbi ezingaphezulu kwe-fiber optic, GYFTY, GYFTS, kanye ne-GYFTA. I-GYFTA iwumgogodla ongaqinisiwe, i-aluminium armored fibre optic cable. I-GYFTS iwumgogodla ongaqinisiwe ongeyona eyensimbi, intambo yensimbi ye-armored fibre optic.
Ikhebula le-GYFTY fibre optic lithatha isakhiwo esisontekile se-loose-layer, futhi i-optical fibre imbozwe eshubhuni elixegayo elenziwe ngezinto ze-high-modulus polyester, futhi ishubhu ligcwaliswa ngenhlanganisela engangeni manzi. Ishubhu elixegayo (kanye nentambo yokugcwalisa) lisontekile lizungeze i-non-metallic central reinforcement (FRP) libe yinkambo yekhebula elihlangene, futhi izikhala kunkambo yekhebula zigcwaliswa ngamafutha avimba amanzi. Extri-polyethylenee sheath ngaphandle tyena ikhebulaumnyombo.
Ikhebula le-GYFTA le-fiber optic lamukela isakhiwo esisontekile se-loose-layer, futhi i-optical fiber imbozwe eshubhuni elixegayo elenziwe ngezinto ezisezingeni eliphakeme ze-polyester, futhi ishubhu ligcwaliswa ngenhlanganisela engangeni manzi. Ishubhu elixegayo (kanye nentambo yokugcwalisa) lisontekile lizungeze i-non-metallic central reinforcement (FRP) libe yinkambo yekhebula elihlangene, futhi izikhala kunkambo yekhebula zigcwaliswa ngamafutha avimba amanzi. Izikhali ze-aluminium zangaphandle ze-cable core zigoqwe ngobude, bese i-polyethylene sheath ikhishwa. I-GYFTS iyisakhiwo esifanayo ne-GYFTA, efaka esikhundleni sezivikelo ze-aluminium ngeteyipu yensimbi eboshwe kabili.
Ayikho into yensimbi esakhiweni se-GYFTY, elungele izindawo zombani, izindawo zamandla kagesi aphezulu, nezindawo ezinokuphazamiseka okunamandla kazibuthe kagesi. Ngokuvamile, izintambo ze-GYFTA ne-GYFTS fibre optic nazo zingasetshenziselwa ugesi, ezindaweni ezinezidingo eziphansi zemvelo. I-non-metallic FRP central reinforcing core, ukusebenza kahle kwe-tensile, intambo ye-fiber optic elwa ne-anti-conductive Izici zomkhiqizo: ukuqinisa okungezona ezensimbi (FRP), ezifanele izindawo zombani, izindawo ezinamandla kagesi, ezimelene nombani; Ukushaqeka, kungagotshwa ngokuphindaphindiwe, kusontwe, ukusonteka, ukugoba (i-angle yokugoba engeqi ku-90 °), ukudubula kwesibhamu, njll., ngezakhiwo ezinhle zemishini; umjikelezo wokushisa ozinzile, igobolondo eliphelele, ukuconsa okunqanda ukubola, ukubuyiswa komlilo nezinye izindawo ezinhle Ukusebenza; Ifayibha elawulwa ngokunembile ubude obudlulele kanye nephimbo lokuxhuma ikhebula kuqinisekisa ukuthi ikhebula le-fiber optic linokusebenza okuhle kakhulu okuqinile kanye nezici zokushisa; iminyaka yokuphila ingaphezu kweminyaka engama-30. Isisindo esincane, ubude bekhebula elincane, nomthwalo omncane emibhoshongweni.
