Dulmar Kooban
SR1002 qaataha indhaha waa 1GHz CATV/FTTB-qaade-qaade-geeseedkayagii ugu dambeeyay. Iyada oo leh tiro balaadhan oo ah helitaanka awoodda indhaha, heerka wax soo saarka sare, iyo isticmaalka tamarta hoose. Waa qalabka ugu habboon ee lagu dhisi karo shabakad NGB oo tayo sare leh.
Tilmaamaha Waxqabadka
- Qaado farsamada AGC indhaha ee horumarsan, kala duwanaanta xakamaynta AGC indhaha: +2dBm ~ -9/-8/-7/-6/-5/-4dBm la hagaajin karo;
- Soo noqnoqoshada shaqada hore ee loo fidiyay 1GHz, qaybta cod-weyneeye RF waxay qabataa waxqabadka sare ee isticmaalka tamarta hoose ee GaAs chip, heerka ugu sarreeya ee wax soo saarka ilaa 106dBuv;
- EQ iyo ATT labaduba waxay isticmaalaan wareegga kontoroolka korantada ee xirfadleyda ah, taasoo ka dhigaysa kantaroolka mid sax ah, iyo hawlgal ku habboon;
- Ku dhex-dhisay jawaab-celiyaha maamulka shabakada heerka II fasalka.
- Taageerida maareynta shabakada fog (ikhtiyaar);
- Iyada oo qaab dhismeed isku dhafan, iyo rakibid ku habboon, waa xulashada koowaad ee qalabka shabakadda FTTB CATV;
- La isku halleyn karo oo la isku halleyn karo oo la isku halleyn karo oo la isku halleyn karo oo hooseysa;
- Summada la habeeyey iyo Naqshad Xidhid la heli karo
