I-GYFJH
Ikhebuli yangaphakathi nengaphandle
I-GYFJH
Incazelo Yomkhiqizo
Ikhebuli yeremote ye-fibre optic yerediyo ye-GYFJH. Isakhiwo se-intambo yokubonaisebenzisa imicu emibili noma emine yemodi eyodwa noma enemodi eningi embozwe ngokuqondile ngezinto ezinomusi omncane kanye ne-halogen ukuze yenze i-tight-buffer fiber, ikhebula ngalinye lisebenzisa intambo ye-aramid enamandla aphezulu njengento eqinisayo, futhi ikhishwa ngongqimba lwe-LSZH engaphakathi emgodleni. Phakathi naleso sikhathi, ukuze kuqinisekiswe ngokugcwele ukujikeleza kanye nezici zomzimba nemishini yekhebula, izintambo ezimbili zokugcwalisa i-aramid fiber zibekwe njengezinto zokuqinisa, Ikhebula le-Sub kanye neyunithi yokugcwalisa iyasonteka ukuze yenze umgogodla wekhebula bese ikhishwa nge-LSZH emgodleni wangaphandle (i-TPU noma enye impahla ye-sheath evunyelwene nayo iyatholakala ngesicelo).

IPHAKEJI NOMAKA
IPHAKETHI
Akuvunyelwe amayunithi amabili ubude bekhebula esigubhuni esisodwa, iziphetho ezimbili kufanele zivalwe, iziphetho ezimbili kufanele
igcwele ngaphakathi kwesigubhu, igcine ubude bekhebula obungekho ngaphansi kwamamitha ama-3.
UMARKO
Ikhebuli izomakwa unomphela ngesiNgisi ngezikhathi ezithile ngolwazi olulandelayo:
1.Igama lomkhiqizi.
2.Uhlobo lwekhebula.
Isigaba se-3.Fiber.
UMBIKO WOKUHLOLA
Umbiko wokuhlolwa nesitifiketi esihlinzekwe ngesicelo.

I-Loose Tube Corrugated Steel/Aluminium Tape Flame...
Imicu ibekwe eshubhuni elixegayo elenziwe nge-PBT. I-tube igcwele inhlanganisela yokugcwalisa ukumelana namanzi, futhi ucingo lwensimbi noma i-FRP itholakala phakathi nendawo ephakathi njengelungu lamandla ensimbi. Amashubhu (kanye nama-filler) aboshwe eduze kwelungu lamandla abe yingqikithi ehlangene futhi eyindilinga. I-PSP isetshenziswa isikhathi eside phezu komgogodla wekhebula, ogcwele inhlanganisela yokugcwalisa ukuyivikela ekungeneni kwamanzi. Ekugcineni, ikhebula ligcwaliswa ngeshethi ye-PE (LSZH) ukuze inikeze ukuvikeleka okwengeziwe.

OYI-FOSC-M5
Ukuvalwa kwe-OYI-FOSC-M5 dome fibre optic splice kusetshenziswa ku-aerial, ukukhwezwa odongeni, kanye nasezinsizeni ezingaphansi komhlaba ukuze kusetshenziswe uhlaka oluqondile nolukagatsha lwentambo yefayibha. Ukuvalwa kwe-Dome splicing kuwukuvikela okuhle kakhulu kwamajoyinti e-fiber optic ezindaweni ezingaphandle ezifana ne-UV, amanzi, nesimo sezulu, ngokuvaleka okungavuzi nokuvikeleka kwe-IP68.

I-OYI-F235-16Core
Leli bhokisi lisetshenziswa njengendawo yokunqamula ukuze ikhebuli yokuphakelayo ixhumeke ngentambo yokudonsaUhlelo lwenethiwekhi yokuxhumana ye-FTTX.
Ihlanganisa i-fiber splicing, ukuhlukanisa, ukusatshalaliswa, ukugcinwa nokuxhumeka kwekhebula kuyunithi eyodwa. Ngaleso sikhathi, ihlinzeka ngokuvikeleka okuqinile nokuphathwa kweIsakhiwo senethiwekhi ye-FTTX.
Uma ufuna isisombululo sekhebula le-fiber optic esithembekile, esinesivinini esikhulu, ungabheki kude kune-OYI. Xhumana nathi manje ukuze ubone ukuthi singakusiza kanjani uhlale uxhumekile futhi siyise ibhizinisi lakho ezingeni elilandelayo.
