GLB3500M-3 Terr TV le One wideband LNB holim'a fiber
Tlhaloso ea Sehlahisoa
GLB3500M-3 ke sehokelo sa modular CWDM Broadband RF fiber, se fetisang tse peli 290MHz ~ 2350MHz Satellite RF (e ts'ehetsa UK 290MHz ~ 2340MHz kapa Europe 300MHz ~ 2350MHz) le 45MHz ~ 806MHz Terrestrial fiber SM e le 'ngoe. Broadband RF e ho 1530nm kapa 1550nm, terrestrial TV RF e ho 1570nm. Ho na le fiber optic CWDM mux kapa sesebelisoa sa demux ho transmitter ea optical kapa ho amohela ho hlokomela phetiso e le 'ngoe ea fiber.
SMATV (Satellite Master Antenna TV) e tumme ho fana ka TV ea sathelaete le TV ea lefatše ho ba ngolisitseng ba lulang lifoleteng kapa sechabeng. Traditional SMATV e ka tsamaisa litaba tsa antenna tse kholo ka li-multiswitch ho li-satellite tse amohelang ka thapo ea coaxial. Ka lebaka la tahlehelo e phahameng ea maqhubu a holimo a sathelaete, sebaka sa cable sa SMATV se ka tlase ho limithara tse 150 leha e le ka amplifier ea inthaneteng ea IF. Ho fapana le sistimi e tloaelehileng ea Quattro LNB SMATV, sistimi e kholo ea LNB SMATV e na le lihokelo tsa halofo tsa RF le linomoro tsa cable tse halofo, tse bolokang litšenyehelo tsa phetisetso. Ka mor'a hore fiber e kene mohahong, SMATV Optical Receiver e tlameha ho sebetsa le dCSS multiswitch ho ba le tlhahiso e le 'ngoe ea RF e nang le li-userband tse 32 tse matla, moo mosebelisi e mong le e mong a ngolisitseng satellite ea STB a le mong. Fiber ena e le 'ngoe mohahong le mohala o le mong oa coaxial ho basebelisi ba bangata mohahong o etsa hore ho be bonolo ho kenya le ho lokisa lithapo.
Sehokelo sa fiber sa GLB3500M-3 se kenyelletsa transmitter ea GLB3500M-3T le GLB3500M-3R e amohelang mahlo. Ka CWDM lasers / photodiode le lerata le tlaase la RF e fumana taolo ea potoloho, e le 'ngoe ea GLB3500M-3T e ka fana ka RF ea boleng bo phahameng ho ea ho 32pcs GLB3500M-3R e amohelang optic ka ho toba.
Likarolo tse ling:
• Ntlo ea aluminium e tiileng.
• 3 e ikemetseng ea Broadband RF holim'a phetiso e le 'ngoe ea SM fiber.
• Boema-fofane bo bong le bo bong ba RF: wideband LNB 290~2350MHz kapa 45~806MHz.
• High Linearity Photodiode.
• Lerata le tlase la RF Gain Control circuit.
