Intambo yeMicro Fiber yangaphakathi GJYPFV(GJYPFH)
Ulwakhiwo lwentambo ye-FTTH ye-optical yangaphakathi lulandelayo: embindini kukho iyunithi yonxibelelwano lwe-optical. Iintambo ezimbini ze-Fiber Reinforced (FRP/Steel wire) ezihambelanayo zibekwe kumacala omabini. Emva koko, intambo igcwaliswa nge-Lsoh Low Smoke Zero Halogen (LSZH/PVC) sheath emnyama okanye enemibala.

I-Clevis ene-insulated yentsimbi
I-Clevis efakwe i-insulation luhlobo olukhethekileyo lwe-clevis eyenzelwe ukusetyenziswa kwiinkqubo zokusasazwa kwamandla ombane. Yakhiwe ngezinto zokukhusela ezifana ne-polymer okanye i-fiberglass, ezigquma izinto zesinyithi ze-clevis ukuthintela ukuhanjiswa kombane ezisetyenziselwa ukuncamathisela ngokukhuselekileyo ii-conductor zombane, ezifana neentambo zombane okanye iintambo, kwii-insulators okanye kwezinye izixhobo kwi-utility poles okanye izakhiwo. Ngokuhlukanisa i-conductor kwi-clevis yesinyithi, ezi zinto zinceda ukunciphisa umngcipheko weempazamo zombane okanye ii-short circuits ezibangelwa kukudibana ngengozi ne-clevis. Ii-Spool Insulator Bracke zibalulekile ekugcineni ukhuseleko kunye nokuthembeka kweenethiwekhi zokusasazwa kwamandla.

I-Loose Tube Corrugated Steel/Aluminium Tape Flame...
Iifayibha zibekwe kwityhubhu ekhululekileyo eyenziwe nge-PBT. Ityhubhu izaliswe yi-compound yokuzalisa engangeni manzi, kwaye ucingo lwentsimbi okanye i-FRP lubekwe embindini we-core njengelungu lamandla esinyithi. Iityhubhu (kunye nezizalisi) zibotshelelwe zijikeleze ilungu lamandla zibe yi-core encinci nejikelezayo. I-PSP isetyenziswa ixesha elide phezu kwe-core yekhebula, ezaliswe yi-compound yokuzalisa ukuyikhusela ekungeneni kwamanzi. Ekugqibeleni, ikhebula lizaliswa nge-sheath ye-PE (LSZH) ukubonelela ngokhuseleko olongezelelweyo.
Ukuba ufuna isisombululo sentambo ye-fiber optic ethembekileyo nekhawulezayo, khangela i-OYI. Nxibelelana nathi ngoku ukuze ubone indlela esinokukunceda ngayo uhlale uqhagamshelene kwaye unyuse ishishini lakho liye kwinqanaba elilandelayo.
