GLB3500E-2R satellite TV FTTH Optical LNB ke fiber optic receiver e fetolang lets'oao la optical ho RF bakeng sa li-satellite tse 4 tse amohelang lehae le le leng.Ho sebetsa le Greatway GLB3500E-2T satellite TV optical transmitter, GLB3500E-2R e na le mojule oa SatCR o hahelletsoeng o sebetsanang le wideband satellite RF, e hlahisa lihlopha tse 4 tsa basebelisi ba sathelaete boema-kepeng bo le bong ba SatCR RF bakeng sa baamoheli ba sathelaete ba 4 ba sa sebetseng.

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 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.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 e tšehetsang DiSEqC.

GLB3500E-2R e na le boema-kepe ba khetho ea 1310nm/1490nm/1550nm WDM bakeng sa ho sebelisana le GPON ONU ts'ebelisong efe kapa efe ea FTTH, e nolofalletsang hore likahare tsa satellite tsa Quattro LNB li kenngoe tsamaisong ea GPON.
