Hordhac:ONU(Cutubka Shabakadda indhaha) waxa loo qaybiyaa unug shabakad indho-indhayneed oo firfircoon iyo unugga shabakadda indhaha ee dadban,ONUwaa aaladda terminalka isticmaalaha ee shabakada indhaha, oo la dhigo dhamaadka isticmaalaha, loo isticmaaloOLTsi loo gaaro Ethernet Layer 2, lakabka 3, si loo siiyo isticmaalayaasha adeegyada codka, xogta iyo warbaahinta badan.
ONUSharaxaadda tilmaame guddi:
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 cilladaha waa cilladaha khadka fiber optic iyoONUcilladaha qalabka. Marka hore, hubi in tilmaamuhu uu caadi yahay iyo in kale. Haddii ay dhacdo in uu xumaado khadka fiber optic-ga, 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 shaqada ee caadiga ahONUwaxaana 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.Haddii khadka fiber-ka indhaha uu cilladaysan yahay: marka hore ka saar pigtail-kaONUsi aad u tijaabiso awooda indhaha, haddii aanu jirin iftiin ama korontodu aanay u qalmin, fadlan u tag cidhifka sanduuqa xawilaadda fiilada indhaha si aad u heshid mid ka mid ah 1-32 pigtails ee kala qaybiyaha indhaha ee u dhigmaONUHaddii 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 saameyn doonta dhammaanONU.
ONUSharaxaadda tilmaame guddi:
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 haddii ayONUqalabku si caadi ah ayuu u shaqaynayaa (haddii iftiinka tilmaamaya ee qalabka qalabka uu yahay mid caadi ah), ka dibna hubi sababaha kale ka dib marka qalabku si caadi ah u shaqeeyo. Nidaamku wuxuu la mid yahay kan kore.
