GFH2000-K TV le Sat Fiber Optic LNB
Tlhaloso ea Sehlahisoa
GFH2000-K ke 45~2600MHz 1550nm faeba optic seamohedi se nang le boema-kepe ba WDM ho ya FTTH ONU. Joaloka motheo oa fiber optic LNB, GFH2000-K e na le LNB e pharaletseng (300MHz ~2350MHz) kapa LNB e tloaelehileng (950MHz~2150MHz)+CATV RF RF, e sebetsa le GWT3500S (CATV+Sat) fiber optic transmitter kapa GLB3500MTr TV-D (Terr+D) Sat IF) fiber optic transmitter kapa wideband optical transmitter.
LNB ea kamehla ke Low Noise Block, e fetola Ku Band 10.7GHz~12.75GHz RF kapa C Band 3.7GHz~4.2GHz RF ho isa ho 950MHz~2150MHz IF bakeng sa seamoheli sa setulo. Ho SMATV holim'a fiber system, transmitter e le 'ngoe e fetola LNB IF ho fiber. Kamora amplifier ea fiber optic le PON, lets'oao la optic le abeloa makholo kapa likete tsa malapa a FTTH. Ntlong e 'ngoe le e 'ngoe e nang le thapo ea faeba, seamoheli se le seng sa optical se fetolela fiber ho Sat IF. Kenyelletso ea Fiber e fetohela ho 950MHz ~ 2150MHz IF tlhahiso bakeng sa moamoheli oa setulo.
Satellite optical receiver e bapala karolo e tšoanang le ea LNB e tloaelehileng, ke "virtual" LNB lapeng. Satellite optical receiver e ka bitsoa Optical LNB kapa Fiber LNB.
LNB ea kamehla e kenngoa sejaneng se shebaneng le leholimo. Optical LNB e kentsoe kae kapa kae lapeng moo fiber e fumanehang. Litaba tsa LNB e le 'ngoe e tloaelehileng li ka hlahisoa hape ho fihla ho 500K optical LNBs.
Joalo ka LNB ea bokahohle ea optical, GFH2000-K e ka sebetsa le motho ofe kapa ofe oa boraro GPON ONU kapa 1270nm/1577nm XGPON ONU kapa 1524~1544/1596~1599nm NGPON2 ONU, e kenya lipapatso tse kholo tsa boleng bo holimo tsa CAFTTH SAT ntle le ho ngolisa livideo tsa marang-rang. bandwidth.
Likarolo tse ling:
•High Linearity Photodiode bakeng sa Terrestrial TV le Satellite TV RF.
•45MHz ~ 2600MHz (tlase) RF Output.
•1270nm/1577nm Optical Bypass koung ho XGPON ONU kgetho.
•1524 ~ 1544nm/1596 ~ 1599nm bypass port ho NGPON2 ONU khetho.
•DC Power le optical input LED indicator.
•Boema-kepe ba adaptara ea matla ea 10 ~ 18V DC e ikemetseng.
