GLB2000A-K Terr TV le Fiber Optic Twin LNB
Tlhaloso ea Sehlahisoa
GLB2000A satellite TV FTTH optical LNB e fetola lets'oao la optical ho li polarities tse peli RF bakeng sa seamoheli sa sathelaete se le seng.Ho sebetsa le Greatway GLB3500A-2T satellite TV fiber optic transmitter, GLB2000A e hlahisa boleng bo phahameng ba Terrestrial TV+ Vertical/Horizontal RF signal.LNB ena ea bohlano e ka chencha Letšoao la Vertical (kapa RHCP) kapa Horizontal (kapa LHCP) ka matla a 13V kapa 18V DC ho tsoa ho seamoheli sa sathelaete.
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 ea moamoheli oa setulo.
• Satellite optical receiver e bapala karolo e tšoanang le ea LNB ea kamehla, ke "virtual" LNB lapeng.Satellite optical receiver e ka bitsoa Optical LNB kapa Fiber LNB.
• LNB ea kamehla e kentsoe sejaneng se shebileng leholimong.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 fihlela ho 500K optical LNBs.
• LNB ya ka mehla e na le polarities tse otlolohileng kapa tse tshekaletseng (13V/18V) le sehlopha se phahameng kapa se tlase (0Hz kapa 22KHz).Ka theknoloji ea CWDM/DWDM, optical LNB e ka ba le ts'ebetso e ts'oanang ea boema-kepe ba RF ho tsoa ho fiber e le 'ngoe ea SM.

LNB ea kamehla e kenngoa sejaneng se shebaneng le leholimo.Optical LNB e kentsoe kae kapa kae lapeng moo fiber e fumanehang.Likahare tsa LNB e le 'ngoe e tloaelehileng li ka hlahisoa hape ho fihla ho 500K optical LNBs.
LNB ea kamehla e na le polarities tse otlolohileng kapa tse tšekaletseng (13V/18V) le sehlopha se holimo kapa se tlase (0Hz kapa 22KHz).Ka theknoloji ea CWDM/DWDM, optical LNB e ka ba le ts'ebetso e ts'oanang ea boema-kepe ba RF ho tsoa ho fiber e le 'ngoe ea SM.
GLB2000A e na le khetho ea 1310nm/1490nm WDM bakeng sa ho sebelisana 'moho le GPON/EPON ONU boemong bofe kapa bofe ba FTTH, e leng se nolofalletsang ho kenya DTT+SAT holim'a marang-rang a GPON/EPON.
Likarolo tse ling:
•Ntlo ea lelakabe la polasetiki e thata e thibelang mollo.
•High Linearity Photodiode.
•Kenyelletso ea fiber ea SC/APC.
•Sebaka sa mahlo sa AGC: -6dBm ~ +1dBm.
•Sat RF Bandwidth: 950MHz ~ 2150MHz.
•Terene ea Lefatše ea RF Bandwidth: 174~806MHz.
•Terrestrial TV + Horizontal (LHCP)@18V DC from satellite receiver..
•Lefats'e TV + E otlolohileng (RHCP)@13V DC ho tsoa ho moamoheli oa sathelaete.
•Boikhethelo boema-kepe ba WDM ho ea GPON ONU.
