GFH2000-K TV iyo Sat Fiber Optic LNB
Sharaxaada Alaabta
GFH2000-K waa 45 ~ 2600Mhz 1550nm fiber optic aqbalaha leh dekedda WDM ilaa FTTH ONU.Sida LNB fiber optic aasaasiga ah, GFH2000-K waxay leedahay LNB ballaaran (300MHz ~ 2350MHz) ama LNB joogto ah (950MHz ~ 2150MHz) + CATV RF bands, waxay la shaqeysaa GWT3500S (CATV + Sat) gudbiyaha fiber optic ama GLB3500r TV-D (T) Sat IF) gudbiyaha fiber optic ama gudbiyaha indhaha ballaaran.
LNB-ga joogtada ahi waa Block sanqadh hooseeya, oo u beddelaya Ku Band 10.7GHz~12.75GHz RF ama C Band 3.7GHz~4.2GHz RF ilaa 950MHz~2150MHz HADDII loogu talagalay qaataha fadhiga.Marka SMTV ka sarreeya nidaamka fiber-ka, hal gudbiye ayaa u beddela LNB HADDII fiber.Kadib cod-weyneeye fiber optic iyo PON, signalka optic-ga waxa loo qaybiyaa boqollaal ama kumanaan qoys oo FTTH ah.Guri kasta oo leh fiilada fiber-ka, mid ka mid ah qaataha indhaha ayaa fiber u beddela Sat IF.Gelitaanka fiber-ku wuxuu noqdaa 950MHz ~ 2150MHz HADDII wax soo saarka sat qaataha.
Satellite optical receiver wuxuu ciyaaraa door la mid ah kan caadiga ah ee LNB, waa "virtual" LNB guriga.Satellite optical receiver waxaa loogu yeeri karaa Optical LNB ama Fiber LNB.
LNB joogto ah ayaa lagu rakibay saxanka cirka u jeeda.Optical LNB waxa lagu rakibay meel kasta oo guriga ka mid ah oo fiber laga heli karo.Waxa ku jira hal LNB oo caadi ah ayaa dib loo soo saari karaa ilaa 500K indhaha LNBs.
Sida LNB indhaha caalamiga ah, GFH2000-K waxay la shaqayn kartaa dhinac kasta oo saddexaad GPON ONU ama 1270nm/1577nm XGPON ONU ama 1524 ~ 1544/1596 ~ 1599nm NGPON2 ONU, gelinaya baahinta tayada sare leh oo tayo sare leh oo CATV+SAT videos iyada oo aan la isticmaalin wax internet ah baaxadda.
