ＳＣ/AＰＣ-SC /ACPPre-Connectorized Optical Fiber Drop Cable precess
1. Ikhebula le-FTTH lisikwa libe ngobude obuhlukene ngokwezidingo zentambo yesichibi, ngokuvamile ukusuka ku-1m kuya ku-300m, kodwa singaphinde sisike ngokuvumelana nezinye izidingo.Lesi isinyathelo sokuqala sokwenza intambo yesichibi.
2. Beka izesekeli zokuxhuma kusengaphambili, ngaphambi kokukhumula i-optic fiber.
3.Khipha i-fiber optical futhi ufake izisekeli zokuxhuma ngayinye ngayinye.Ubude be-fiber optical kufanele bubekwe eceleni ukuze kube lula ukusebenza okulandelayo.
I-4.hoting solidify: Ukuze kuqinisekiswe ukuthi amandla okubamba okuhlangene angafinyelela ku-120N, sidinga ukulungisa ukuhlanganiswa ngeglue ekhethekile.Lapha, isikhathi sokwelapha siyihora nesigamu.Sandisa isikhathi sokuphulukisa futhi sandise amandla okuqina ngosayizi wezingxenye zensimbi.
I-5.I-Joint fixed: Le nqubo ibaluleke kakhulu, enquma amandla okumelana okuhlangene.Siye sandisa ubukhulu beshidi lensimbi futhi sandisa inani leglue, ukuze ukuhlanganyela kuqine kakhulu.
6. Hlanganisa isixhumi
I-7.Ukuphela kwe-fiber optic: I-SC/APC ne-SC/UPC Izinqubo ezihlukene zokugaya.Isixhumi ngasinye se-fiber optical sidinga ukugaywa.I-engeli yokugaya iyahlukahluka ngesixhumi.
8. Hlola futhi uhlole.Isixhumi ngasinye sidinga ukuphela kokuhlolwa kanye nedatha yokuhlola engu-100%.
