Intambo ye-optical yangaphandle, ebizwa ngokuba yintambo ye-outdoor-grade, luhlobo lwentambo ye-optical. Ibizwa ngokuba yintambo ye-optical yangaphandle kuba yenzelwe ngokukodwa ukusetyenziswa ngaphandle. Ihlala ixesha elide, iyakwazi ukumelana nomoya, ilanga, ingqele, kunye neqabaka, kwaye inesigqubuthelo sangaphandle esityebileyo. Ikwanazo neempawu zoomatshini kunye nokusingqongileyo ezifana nokumelana noxinzelelo, ukumelana nokugqwala, kunye namandla okutsalwa.
Iintambo ze-optical zangaphandle ezisetyenziswa rhoqo zahlulwe zibe zizakhiwo ezimbini: uhlobo lwetyhubhu ephakathi kunye nentambo ye-optical ejijekileyo.
① Intambo ye-optical yohlobo lwetyhubhu ephakathi: Umbindi wentambo ye-optical yityhubhu ekhululekileyo, kwaye ilungu lokuqinisa libekwe kufutshane netyhubhu ekhululekileyo. Umzekelo, intambo ye-optical yohlobo lwe-GYXTW eqhelekileyo inenani elincinci lee-cores, ngokuqhelekileyo zingaphantsi kwe-12 cores.
Intambo ye-Optical ye-GYXTW:
Umbhobho womqadi: Izinto zembhobho yomqadi yiPBT, eqinileyo, eguquguqukayo, kwaye exhathisa uxinzelelo olusecaleni.
Ngenxa yokuba kukho imibala eli-12 kuphela ye-optical fiber, i-optical cable ye-optical esemgangathweni wesizwe (kwaye ikwangumgangatho wehlabathi) inokuba nee-cores ezili-12 kuphela. Ii-optical cables ezinee-cores ezingaphezu kwe-12 zihlala zijijekile.
2. Intambo ye-Optical ejijekileyo: Iibhanti ezininzi zeefayibha ze-optical zijijekile kunye zijikeleze i-core strength element. Ezi ntambo ze-optical, ezifana ne-GYTS, i-GYTA, njl.njl., zinokudityaniswa neetyhubhu ezikhululekileyo ukwenza ii-cores ezinkulu. Inani leefayibha ze-optical.
Iintambo ze-fiber optic ezinee-cores ezingama-60 okanye ngaphantsi zihlala zisebenzisa isakhiwo see-tube ezi-5. Umzekelo, intambo ye-fiber optic enee-cores ezingama-60 isebenzisa ii-bundles ezi-5 zeetyhubhu, kwaye i-bundle nganye inee-fibers ze-optical ezili-12. Ngokubanzi, iintambo ze-fiber optic ezijijekileyo ezinee-cores ezili-12 okanye ngaphantsi zijijekile kunye ne-bundle yeetyhubhu eziqulethe ii-cores ze-fiber optic ezili-12 kunye nee-filler wires ezi-4 eziqinileyo. Zinokujijeka nee-bundles ezi-2 zee-cores ezi-6 kunye nee-filler wires ezi-3, okanye zidityaniswe ngezinye iindlela.
Intambo ye-GYTS Optical: Phakathi kweentambo ze-optical ezijijekileyo, olu hlobo kunye ne-GYTA zezona zixhaphakileyo. Iinqwaba ezininzi zeetyhubhu zijijelwa kunye kwintambo yentsimbi etyebileyo, ene-phosphate. Izikhewu kwiintambo ezijijekileyo zizaliswa yintambo yentambo evimba amanzi, kwaye ishelufu iqiniswa ibe yi-wrapper yangaphandle emva kwesangqa seteyipu yentsimbi.
Intambo ye-GYTA Optical: Ulwakhiwo lwale ntambo ye-optical lufana ne-GYTS, ngaphandle kokuba umcu wentsimbi uthatyathelwa indawo ngumcu we-aluminiyam. Isalathisi soxinzelelo olusecaleni lomcu we-aluminiyam asiphezulu njengesomcu wentsimbi, kodwa umcu we-aluminiyam unokumelana ngcono ne-antioxidant kunye nokufuma. Kwezinye iindawo ezinee-through-conduits, ukusebenzisa imodeli ye-GYTA kubangela ukuba intambo ye-optical ihlale ixesha elide.
Intambo ye-optical yohlobo lwe-GYFTY: Olu hlobo lwentambo ye-optical luneetyhubhu ezininzi ezidityanisiweyo ezijikelezileyo ezijikeleze isiseko esiqinisiweyo esingesisinyithi. Indawo ejijekileyo izaliswe yintambo yokuncamathelisa okanye ikhuselwe ngeteyiphu yokuvimba amanzi, kwaye i-sheath icinezelwa ngqo ngaphandle ngaphandle kwe-armor. Le modeli ineenguqu ezininzi. Isetyenziswa kwezinye iinkqubo zomoya. Ukwandisa amandla okutsalwa kwentambo ye-optical, i-fiber ye-aramid kunye ne-sheath ekhutshiweyo zongezwa ngaphandle kwesiseko sentambo ejijekileyo. Ukuba i-central reinforcement ayisiyo isiseko esiqinisiweyo esingesisinyithi (FRP) kodwa yintsimbi yentsimbi, imodeli yi-GYTY, F (emele i-non-metallic).
Intambo ye-fiber optic yohlobo lwe-53: Sibona ezinye iimodeli ezifana ne-GYTA53 kunye ne-GYTY53. Le modeli yongeza umaleko wesixhobo sentsimbi kunye nesigqubuthelo kwiintambo ze-fiber optic ze-GYTA kunye ne-GYTY. Isetyenziswa kwiindawo ezineemeko ezinzima. U-"53" ubonisa umaleko owongezelelweyo wesixhobo sentsimbi kunye nesigqubuthelo.
