GFD2000 LNB Dongle

GFD2000 fiber optic LNB Dongle ndi compact satellite TV fiber optic receiver yoikidwa pa RF port of satellite STB.Kugwira ntchito ndi Greatway GLB3500MT optical transmitter, GFD2000 LNB dongle imatembenuza chizindikiro cha kuwala kukhala Satellite RF.Mothandizidwa ndi 13V/18V DC kuchokera ku cholandila satana, GFD2000 imatulutsa ma transponder apamwamba kwambiri a satana popeza mapangidwe osalala.GFD2000 ili ndi satellite yabwino kwambiri ya MER pamagetsi otsika kwambiri (monga -18dBm).

Direct Broadcasting Satellite (DBS) ndi Direct to Home (DTH) ndi njira zodziwika bwino zosangalalira pa TV padziko lonse lapansi.Kuti muchite izi, satellite antenna, coaxial cable, splitter kapena multi-switcher ndi satellite receiver ndizofunikira.Komabe, kukhazikitsa antenna satana kungakhale kovuta kwa olembetsa omwe amakhala m'nyumba.SMATV (satellite mater antenna TV) ndi yankho labwino kuti anthu okhala mnyumbamo kapena ammudzi agawane mbale imodzi ya satellite ndi mlongoti wapa TV wapadziko lapansi.Ndi chingwe cha fiber, chizindikiro cha SMATV RF chikhoza kuperekedwa ku 30Km kutali kapena kugawidwa ku zipinda 32 mwachindunji, ku 320 kapena 3200 kapena 32000 nyumba kudzera pa GWA3530 fiber optic amplifier.

GLB3500MT imatha kusintha ma 32UB opitilira 32UB kuchokera pa satelayiti imodzi kapena ma satelayiti anayi kukhala 1550nm CHIKWANGWANI kudzera pa satellite converter yakunja.20dBm high power version GLB3500MT-D20 imatha kuyendetsa 512pcs GFD2000 LNB Dongles mwachindunji.Izi zimapereka njira yotsika mtengo kwa olembetsa omwe akukhala m'nyumba kapena m'deralo kuti aziwonera zomwe zili zodziwika bwino monga BeIN, OSN ndi zina. pa STB yanthawi zonse kapena decoder yosankhidwa pokhazikitsa dongle ya LNB padoko lake la RF.Chifukwa cha zosefera za 1550nm zomangidwira, GFD2000 ikhoza kukhazikitsidwa pa doko la RF decoder mwachindunji ngakhale wolembetsa alibe GPON/XGPON ONU.
