GFD2000 LNB Dongle
Ingcaciso yeMveliso
I-GFD2000 ifayibha optic i-LNB Dongle yi-compact satellite TV fibre optic receiver efakwe kwi-RF port ye-satellite STB. Ukusebenza nge-Greatway GLB3500MT isidluliseli samehlo, i-GFD2000 LNB dongle iguqula isignali yokukhanya ibe yiSatellite RF. Ixhaswe yi-13V/18V DC ukusuka kumamkeli wesathelayithi, i-GFD2000 ikhupha iitransponder zesathelayithi ezikumgangatho ophezulu ngokufumana uyilo olucaba. I-GFD2000 ine-MER yesathelayithi egqwesileyo kumandla okufaka optical asezantsi kakhulu (afana ne -18dBm).
ISathelayithi yoSasazo oluNgqo (i-DBS) kunye neNgqo kwiKhaya (DTH) yeyona ndlela idumileyo yokonwabela iTV yesathelayithi kwihlabathi jikelele. Ukwenza oko, i-antenna yesathelayithi, intambo ye-coaxial, i-splitter okanye i-multi-switcher kunye ne-satellite receiver iyimfuneko. Nangona kunjalo, ukufakela i-eriyali yesathelayithi kunokuba nzima kubabhalisi abahlala ezindlini. I-SMATV (i-satellite mater antenna TV) sisisombululo esihle kubantu abahlala kwisakhiwo okanye kuluntu ukuba babelane ngesitya esinye se-satellite kunye ne-antenna ye-TV yomhlaba. Ngentambo yefiber, i-SMATV RF isignali inokuhanjiswa kwi-30Km kude okanye isasazwe kumagumbi angama-32 ngokuthe ngqo, ukuya kuma-320 okanye angama-3200 okanye amagumbi angama-32000 nge-GWA3530 fiber optic amplifier.
I-GLB3500MT inokuguqula ubuninzi be-32UB ukusuka kwisathelayithi enye okanye iisathelayithi ezine zibe yifayibha ye-1550nm ngokusebenzisa isiguquli sesathelayithi sangaphandle. I-20dBm inguqulo yamandla aphezulu GLB3500MT-D20 inokuqhuba i-512pcs GFD2000 LNB Dongles ngokuthe ngqo. Oku kunika ababhalisi abahlala ezindlini okanye ekuhlaleni ngendlela eneendleko eziphantsi ukubukela imixholo edumileyo efana ne-BeIN, i-OSN njl.njl Ngenxa yesihluzo esakhelwe ngaphakathi se-1550nm, i-GFD2000 inokufakwa kwi-sat decoder RF port ngqo nokuba umrhumi akanayo GPON/XGPON ONU.
