GFD2000 LNB Dongle
Product Description
GFD2000 fiber optic LNB Dongle yog compact satellite TV fiber optic receiver ntsia ntawm RF chaw nres nkoj ntawm satellite STB. Ua haujlwm nrog Greatway GLB3500MT optical transmitter, GFD2000 LNB dongle hloov kho qhov muag teeb liab rau hauv Satellite RF. Tsim los ntawm 13V / 18V DC los ntawm satellite receiver, GFD2000 outputs zoo satellite transponders los ntawm nce flattened tsim. GFD2000 muaj satellite zoo heev MER ntawm qhov tsis tshua muaj hluav taws xob optical input zog (xws li -18dBm).
Direct Broadcasting Satellite (DBS) thiab Direct to Home (DTH) yog txoj kev nyiam tshaj plaws rau kev txaus siab rau satellite TV thoob ntiaj teb. Txhawm rau ua nws, satellite kav hlau txais xov, coaxial cable, splitter lossis multi-switcher thiab satellite receiver yog tsim nyog. Txawm li cas los xij, kev teeb tsa satellite kav hlau txais xov yuav nyuaj rau cov neeg siv khoom nyob hauv cov tsev. SMATV (satellite mater kav hlau txais xov TV) yog ib qho kev daws teeb meem zoo rau cov neeg nyob hauv lub tsev lossis cov zej zog sib koom ib lub phaj satellite thiab cov kav hlau txais xov hauv av. Nrog fiber ntau cable, SMATV RF teeb liab tuaj yeem xa mus rau 30Km nyob deb lossis faib rau 32 chav ncaj qha, mus rau 320 lossis 3200 lossis 32000 chav tsev ntawm GWA3530 fiber optic amplifier.
GLB3500MT tuaj yeem hloov siab tshaj 32UB los ntawm ib lub satellite lossis plaub lub satellite rau hauv 1550nm fiber ntau ntawm lwm lub satellite converter. 20dBm siab zog version GLB3500MT-D20 tuaj yeem tsav 512pcs GFD2000 LNB Dongles ncaj qha. Qhov no muab txoj hauv kev zoo rau cov neeg siv khoom nyob hauv cov tsev lossis cov zej zog los saib cov ntsiab lus nrov xws li BeIN, OSN thiab lwm yam dhau ntawm lub sijhawm zaum STB lossis tus xaiv zaum zaum decoder los ntawm kev txhim kho LNB dongle ntawm nws qhov chaw nres nkoj RF. Vim lub built-in 1550nm lim, GFD2000 tuaj yeem ntsia tau rau ntawm qhov chaw decoder RF ncaj qha txawm tias tus neeg siv khoom tsis muaj GPON / XGPON ONU.
