Sharaxaadda Badeecada
Sharaxaad Kooban
SR2020AW, oo leh baaxadda shaqaynaysa ee 47~1000MHz, waa qalab saddex-geesood ah oo awood yar, waxqabad sare leh, oo kharash-ool ah, oo qaataha indhaha ee FTTH CATV, Hadday tahay in loo isticmaalo telefishanka analoogga ama telefishanka dhijitaalka ah. Badeecadaha leh tuubo qaataha indhaha oo dareen sare leh iyo wareeg gaar ah oo buuq yar oo isku dheelitiran. Helitaanka awoodda indhaha oo sare waxaa lagu hagaajin karaa heerka PAD, wax soo saarka xaddidan ee la ciyaaray, sidaa darteed SR2020AW gudaha baaxad firfircoon oo ballaaran oo awoodda indhaha ee la helay ee +2 dBm ~-21dBm, waxay leedahay astaamo aad u fiican.
Saddex-jibbaaran, faybar guriga, isticmaalka SR2020AW waxay badbaadin kartaa ilo badan oo koronto oo fiber optic ah. Hawl wadeennada, waxay si weyn u yareyn karaan kharashka dhismaha shabakadda.
Sifooyinka Shaqada
1. Buuqa aadka u hooseeya (3.8% modulate, -10dBm receiver, CNR ≥ 45.3dB)
2. Kala duwanaanshaha awoodda iftiinka ee firfircoon ee ballaaran: gudaha Pin = -16, MER≥36.1dB
3. GPON-ka la dabaqi karo, EPON, oo la jaan qaadi kara tignoolajiyada FTTx PON kasta
4. Waxay badbaadin kartaa tiro badan oo kheyraad koronto oo indhaha ah, waxayna si weyn u yareyn kartaa shabakaddakharashka habaynta
5. Ballaca baaxadda 47 ~ 1000MHz gudahood, dhammaantoodna leh astaamo fidsan oo aad u fiican (FL≤±0.75dB)
6. Kiis bir ah, oo bixiya ilaalin aaladaha xasaasiga ah ee elektaroonigga ah ee indhaha
7. Heerka wax soo saarka sare, kaas oo ay isticmaali karaan dad badan oo isticmaala
8. Isticmaalka korontada oo hooseeya, waxqabad sare, iyo waxqabad kharash sare leh
OGAYSIIS
1. Adaptarka korontada ee qalabkan: Gelinta 110/220V; Wax soo saarka DC 12V(0.6A).
2. Isku xiraha indhaha ka dhig mid nadiif ah, xiriirka xun wuxuu sababi doonaa heer aad u hooseeya oo ah wax soo saarka RF.
3. Waa inaysan iskood isu hagaajin, si looga fogaado dhaawaca qalabka.
