Hordhac: ONU (Cutubka Shabakadda indhaha) waxay u qaybsantaa unugga shabakadda indhaha ee firfircoon iyo unugga shabakadda indhaha ee dadban. , si loo siiyo isticmaalayaasha adeegyada codka, xogta iyo warbaahinta badan.
Sharaxaadda tilmaamayaasha guddiga ONU:
Iftiinka korontadu: Cagaar Demin: Korontada oo xumaada;Cagaaran: Daar
Iftiinka PON: Cagaar shid: dheer oo shid waxay tusinaysaa in guddigu ka gudbay is-tijaabada oo qalabku si caadi ah u shaqeeyo
LOS Light: Off: Caadi
Cilada isticmaale garsoore:
Inta badan ciladaha waa cilladaha khadka fiber indhaha iyo cilladaha qalabka ONU.Marka hore, hubi in tilmaamuhu uu caadi yahay iyo in kale.Haddii ay dhacdo in khadka fiber optic-ga uu xumaado, fiiri heerka iftiinka PON: haddii iftiinka PON uu cagaar yahay, waxay muujineysaa in khadka fiber-ka indhaha uu yahay mid caadi ah, haddii nalka PON uu maqan yahay, waxay muujineysaa in khadka fiber-ka indhaha uu go'ay.
Ku tijaabi xariiqda fiber optic mitirka awoodda indhaha.Qiyaasta u qalma ee awoodda indhaha waa: 1490nm kala duwan: - 8dB ilaa - 28dB.Haddii ay dhaafto xadka, waxay saamayn doontaa tayada shaqo ee caadiga ah ee ONU waxaana saamayn doonta gelitaanka internetka ee isticmaalaha.Hubi khadka fiber indhaha ee heerka sare oo tijaabi fiilada dabada ee kala qaybiyaha u dhigma fiilada indhaha ee isticmaalaha khaldan ee sanduuqa fiilada indhaha.
Hoos-u-dhigista 2-way kala qaybinta indhaha waa -3db
Hoosudhaca 4-way kala qaybinta indhaha waa -6db
Hoosudhaca 8-way kala qaybinta indhaha waa -9db
Hoosudhaca 16-way kala qaybinta indhaha waa -12db
Hoosudhaca 32-way kala qaybinta indhaha waa -15db
Hoosudhaca 64-way kala qaybinta indhaha waa -18db
1.Haddii awoodda wax soo saarka ee pigtail splitter ay u qalanto, fadlan ku beddel xudunta fiber u dhexeeya sanduuqa wareejinta fiilada indhaha iyo dhismaha.Guud ahaan, waxaanu dhignaa ugu yaraan laba xargo oo fiber ah dhismaha, ka dibna tijaabi dhamaadka ka dib beddelka.Haddii ay tahay dabada ka timaadda kala qaybiyaha oo awoodeeda indhaha ee fiber-ku aanay u qalmin, fadlan beddel pigtail-ka firaaqada ah, oo isticmaal mitirka awoodda indhaha si aad u tijaabiso mid u qalma si aad ugu xidho pigtail dhismaha.
2.If line fiber optical waa cilad: marka hore ka saar pigtail on ONU si ay u tijaabiso awoodda indhaha, haddii aysan jirin iftiin ama koronto waa mid aan u qalmin, fadlan tag flange ee sanduuqa wareejinta cable indhaha si aad u hesho mid ka mid ah. 1-32 pigtails ee kala qaybinta indhaha ee u dhiganta ONU Haddii pigtail uusan u qalmin, waxaad bedeli kartaa mid ka mid ah 1-32 doofaarrada aan shaqayn.Xusuusnow: fiber-ka ugu weyn ee kala-qaybiyaha indhaha lama soo saari karo, taas oo saamayn doonta dhammaan ONU.
Sharaxaadda tilmaamayaasha guddiga ONU:
Iftiin koronto: Iftiinka cagaaran mar walba waa shidan: Koronto shid;Nalka cagaarka ah oo dansan: Korontada demi
LOS Light: Off: Awoodda indhaha ee la helay ee dekedda PON waa caadi;Iftiinka cagaaran had iyo jeer waa shidan: Qalabka waa la helay oo waa la diiwaangeliyay;Iftiinka cagaarka ah: Qalabku xog ma leh;Blink: Dekadda PON ma laha iftiin ama awoodda indhaha ayaa ka hooseysa dareenka helitaanka.
LAN1, LAN2, LAN3 iyo LAN4 dhamaantood waa 4RJ45 Port
FXS1 waa Deked Cod
Cilad-bixinta: Marka hore, hubi in aaladda ONU uu si caadi ah u shaqeynayo (haddii iftiinka tilmaamaya ee guddiga qalabka uu yahay mid caadi ah), ka bacdina hubi sababo kale kadib marka uu qalabku si caadi ah u shaqeeyo.Nidaamku wuxuu la mid yahay kan kore.
