GLB3500M-8 Terr TV le Two Quattro LNBs holim'a fiber
Tlhaloso ea Sehlahisoa
GLB3500M-8ke a8ch CWDM Satellite RF fiber link, e fetisang8IFs ho tloha2Li-LNB tsa Quattro ho2Lijana tse fapaneng tsa Satellite le 1 terrestrial TV RF holim'a fiber e le 'ngoe ea SM ho ba ngolisitseng ba bangata.Leqhubu le leng le le leng la CWDM optical wavelength le na le leqhubu le le leng la 950 ~ 2150MHz RF (kapa 174 ~ 2150MHz, ho kenyelletsa le TV ea Terrestrial), e netefatsang ts'ebetso e ntle ea RF le ho itšehla thajana har'a polarities ea sathelaete.
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.Sistimi e tloaelehileng ea Quattro LNB SMATV e hloka likhoele tse 9 tsa RF ho tloha marulelong a moaho ho ea ho li-multiswitch tse ngata, tse sebeletsang ba ngolisitseng ba ka tlase ho 100 mohahong o le mong.GLB3500M-8 e nolofalletsa SMATV holim'a fiber ho mehaho e mengata le ba ngolisitseng.Hammoho le PLC fiber splitter le cascading multiswitch mohahong o mong le o mong, GLB3500M-8 e ka aba tse peli tsa Quattro LNBs le Terr TV ho palo e ka holimo ho 3200 ba ngolisitseng sechabeng.Ena ke sesebelisoa se tloaelehileng sa hybrid fiber coaxial ho TV ea satellite.
Khokahano ea fiber ea GLB3500M-8 e kenyelletsa GLB3500M-8T fiber optic transmitter le GLB3500M-8R fiber optic receiver.Ka CWDM lasers/photodiode le lerata le tlase la RF e fumana taolo ea potoloho, GLB3500M-8T e le 'ngoe e ka fana ka RF ea boleng bo holimo ho ea ho 32pcs GLB3500M-8R e amohelang optical e phahameng ka har'a sebaka sa 5Km fiber.
