GFD2000 LNB Dongle

GFD2000 fiber optic LNB Dongle waa satalayt is haysta oo TV-ga fiber optic qaataha ah oo lagu rakibay dekedda RF ee dayax gacmeedka STB.La shaqaynta Greatway GLB3500MT gudbiyaha indhaha, GFD2000 LNB dongle waxay u beddeshaa signalka indhaha ee Satellite RF.Ku shaqaynta 13V/18V DC ee qaata satalaytka, GFD2000 waxa ay soo saartaa transponders dayax gacmeed tayo sare leh iyada oo heleysa nakhshad fidsan.GFD2000 waxa uu leeyahay dayax gacmeedka MER oo aad u hooseeya oo leh awood galinta indhaha oo aad u hooseeya (sida -18dBm).

Satellite-ka tooska ah ee baahinta tooska ah (DBS) iyo Tooska u ah Guriga (DTH) waa habka ugu caansan ee looga raaxaysto TV-ga satalaytka adduunka oo dhan.Si taas loo sameeyo, anteenada dayax-gacmeedka, fiilada coaxial, kala qaybisa ama beddelaha badan iyo qaataha dayax-gacmeedku waa lagama maarmaan.Si kastaba ha ahaatee, rakibidda anteenada dayax-gacmeedka ayaa laga yaabaa inay ku adkaato macaamiisha ku nool guryaha.SMTV (satellite mater antenna TV) ayaa ah xal wanaagsan oo dadka ku nool dhismaha ama bulshada ay wadaagaan hal saxan oo satelite-ka ah iyo anteenada TV-ga dhulka.Xadhkaha fiber-ka, SMTV RF signal waxa la geyn karaa 30Km ka fog ama waxa loo qaybin karaa 32 guri oo toos ah, 320 ama 3200 ama 32000 guri oo la sii marinayo GWA3530 fibre optic amplifier.

GLB3500MT waxay u rogi kartaa ugu badnaan 32UB hal dayax-gacmeed ama afar dayax-gacmeed oo u rogi kara 1550nm fiber iyada oo loo marayo beddelaha dayax-gacmeedka dibadda.20dBm nooca awoodda sare ee GLB3500MT-D20 wuxuu si toos ah u wadi karaa 512pcs GFD2000 LNB Dongles.Tani waxay siinaysaa hab kharash-ku-ool ah macaamiisha ku nool guryaha dabaqyada ama bulshada si ay ugu daawadaan waxyaabaha caanka ah sida BeIN, OSN iwm. fadhiga caadiga ah ee STB ama sat decoder la magacaabay iyadoo ku rakibaysa LNB dongle dekeddeeda RF.Sababo la xiriira shaandhada 1550nm ku dhex jirta, GFD2000 waxaa lagu rakibi karaa sat decoder RF dekedda si toos ah xitaa haddii macaamiishu uusan lahayn GPON/XGPON ONU.
