GFD2000 LNB Dongle
Whakaahuatanga Hua
GFD2000 muka whatu LNB Dongle ko te kiato TV pee'utari muka whatu kaiwhiwhi tāuta i te tauranga RF o amiorangi STB. Ma te mahi tahi me Greatway GLB3500MT kaiwhakawhiti whatu, GFD2000 LNB dongle ka huri te tohu whatu ki Satellite RF. I whakakahangia e te 13V/18V DC mai i te kaiwhiwhi amiorangi, ka whakaputa a GFD2000 i nga transponder amiorangi kounga teitei ma te whai hoahoa papatahi. Kei a GFD2000 te pai o te amiorangi MER me te iti rawa o te mana whakauru whatu (penei i te -18dBm).
Ko te Maataki Whakaata Tika (DBS) me te Tika ki te Kainga (DTH) te huarahi tino rongonui ki te pai ki te pouaka whakaata amiorangi puta noa i te ao. Hei mahi, he mea tika te antenna amiorangi, te taura coaxial, te wehenga, te whakahuri-maha ranei, me te kaiwhiwhi amiorangi. Heoi, he uaua pea te whakaurunga antenna ki nga kaiohauru e noho ana i nga kaainga. Ko te SMATV (antenna TV satellite mater) he otinga pai mo nga tangata e noho ana i te whare, i te hapori ranei ki te tiritiri i tetahi rihi peerangi me te antenna TV terrestrial. Ma te taura muka, ka taea te tuku tohu SMATV RF ki te 30Km tawhiti, ka tohatohahia ranei ki nga kaainga 32 tika, ki te 320, 3200, 32000 ranei nga whare ma te GWA3530 fiber optic amplifier.
Ka taea e GLB3500MT te huri i te 32UB teitei mai i tetahi amiorangi e wha ranei nga peerangi ki te muka 1550nm ma te kaitahuri amiorangi o waho. 20dBm putanga mana teitei GLB3500MT-D20 ka taea te taraiwa 512pcs GFD2000 LNB Dongles tika. He huarahi whai hua tenei mo nga kaiohauru e noho ana i roto i nga kaainga, i te hapori ranei ki te maataki i nga korero rongonui penei i te BeIN, OSN me etahi atu i runga i te STB noho noa, i te kaiwhakawhanake nohoanga ranei kua tohua ma te whakauru i te dongle LNB ki tana tauranga RF. Na te tātari 1550nm i hangaia, ka taea te whakauru i te GFD2000 ki te tauranga RF decoder noho tika ahakoa kaore he GPON / XGPON ONU te kaiohauru.
