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).

I-Anchoring Clamp PA1500
I-anchoring cable clamp ingumkhiqizo wekhwalithi ephezulu futhi ohlala isikhathi eside. Iqukethe izingxenye ezimbili: ucingo lwensimbi engagqwali kanye nomzimba wenayiloni oqinisiwe owenziwe ngepulasitiki. Umzimba we-clamp wenziwe ngepulasitiki ye-UV, enobungane futhi ephephile ukuyisebenzisa ngisho nasezindaweni ezishisayo. I-FTTH anchor clamp yakhelwe ukuthi ilingane nemiklamo ehlukahlukene yekhebula le-ADSS futhi ingabamba izintambo ezinobubanzi obungu-8-12mm. Isetshenziswa ezintanjeni ze-fiber optic ezifile. Ukufaka ukufaka ikhebula lokudonsa le-FTTH kulula, kodwa ukulungiswa kwentambo yokubona kuyadingeka ngaphambi kokuyinamathisela. Ukwakhiwa okuzikhiya kwe-hook evulekile kwenza ukufakwa kwezigxobo ze-fiber kube lula. I-anchor FTTX optical fibre clamp kanye nabakaki bekhebula lentambo yokudonsa kuyatholakala ngokwehlukana noma ndawonye njengenhlangano.
Izinsimbi zokunamathisela izintambo ze-FTTX ziphumelele ekuhlolweni okuqinile futhi zihlolwe emazingeni okushisa asukela ku- -40 kuya ku-60 degrees. Baphinde bahlola izinga lokushisa ngamabhayisikili, ukuhlolwa kokuguga, nokuhlola ukumelana nokugqwala.

OYI-FATC 16A Terminal Box
I-16-core OYI-FATC 16Ai-optical terminal boxisebenza ngokuhambisana nezidingo ezijwayelekile zomkhakha ze-YD/T2150-2010. Isetshenziswa kakhulu ku-Isistimu yokufinyelela ye-FTTXisixhumanisi setheminali. Ibhokisi lenziwe nge-PC enamandla amakhulu, i-ABS plastic alloy injection molding, ehlinzeka ngokuvaleka okuhle nokumelana nokuguga. Ngaphezu kwalokho, ingalengiswa odongeni ngaphandle noma endlini ukuze ifakwe futhi isetshenziswe.
Ibhokisi letheminali le-OYI-FATC 16A linomklamo wangaphakathi onesakhiwo songqimba olulodwa, ohlukaniswe endaweni yomugqa wokusabalalisa, ukufakwa kwentambo yangaphandle, ithreyi ye-fiber splicing, kanye nesitoreji sekhebula sokudonsa se-FTTH sokudonsa. Imigqa ye-fiber optical icace kakhulu, okwenza kube lula ukusebenza nokuyinakekela. Kunezimbobo zekhebula ezi-4 ngaphansi kwebhokisi ezikwazi ukumumatha izintambo ezi-4 zangaphandle zokuhlangana okuqondile noma okuhlukile, futhi ingafaka izintambo zokubona ezidonsayo ezingu-16 FTTH ukuze kuxhunywe ekugcineni. Ithreyi ye-fiber splicing isebenzisa ifomu eliphendukile futhi ingalungiselelwa ngezicaciso zomthamo wama-cores angu-72 ukuze ihlangabezane nezidingo zokunwetshwa zebhokisi.
Uma ufuna isisombululo sekhebula le-fiber optic elithembekile, elinesivinini esiphezulu, ungabheki kude kune-OYI. Xhumana nathi manje ukuze ubone ukuthi singakusiza kanjani uhlale uxhumekile futhi siyise ibhizinisi lakho ezingeni elilandelayo.
