GLB3500A-2R Twin Fiber Optic LNB
Tlhaloso ea Sehlahisoa
GLB3500A-2R satellite LHCP/RHCP FTTH Optical LNB ke fiber optic receiver e fetolang lets'oao la optical ho ba RF bakeng sa li-satellite tse fetang tse peli tse amohelang. Ho sebetsa le Greatway GLB3500A-2T satellite TV fiber optic transmitter, GLB3500A-2R e hlahisa boleng bo phahameng ba Terrestrial TV+ LHCP le Terrestrial TV + RHCP RF pontšo ho lelapa le le leng le nang le li-satellite tse fetang tse peli tse amohelang. FTTH Twin LNB ena e ka ba le liphetho tse peli tsa RF, boema-kepe bo bong le bo bong ba RF bo ka chencha LHCP kapa lets'oao la RHCP ka matla a 13V kapa 18V DC ho tsoa ho seamoheli sa sathelaete.
Ka mehlaLNBkeLoaNoiseBnotlela, ho fetolela Ku Band 10.7GHz~12.75GHz RF kapa C Band 3.7GHz~4.2GHz RF ho isa ho 950MHz~2150MHz IF bakeng sa moamoheli o lutseng. 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 fihlela 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.
GLB3500A-2R e na le khetho ea 1310nm / 1490nm WDM bakeng sa ho sebelisana 'moho le GPON/EPON ONU boemong leha e le bofe ba FTTH, e leng se nolofalletsang ho kenya TV ea sathelaete holim'a marang-rang a GPON/EPON.
Likarolo tse ling:
•Ntlo ea aluminiamo e kopaneng ea die-cast
•High Linearity Photodiode
•SC/APC fiber input
•Sebaka sa mahlo sa AGC: -6dBm ~ +1dBm
•Sat RF Bandwidth: 950MHz ~ 2150MHz
•Terene ea Lefatše ea RF Bandwidth: 174MHz ~ 806MHz
•Tlhahiso ea RF: Lefats'e la TV + LHCP@18V DC
•Tlhahiso ea RF: Lefats'e la TV + RHCP@13V DC
•CE e amohetsoe
•Boikhethelo boema-kepe ba WDM ho ea GPON ONU
