GLB3500M-16 Terr TV le Four Quattro LNBs holim'a fiber
Tlhaloso ea Sehlahisoa
GLB3500M-16 ke 16ch CWDM Satellite RF fiber link, e fetisetsang 16 IFs ho tloha 4 Quattro LNBs ho 4 Dishes Satellite Dishes 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 lets'oao le le leng la 950 ~ 2150MHz RF (kapa 174 ~ 2150MHz, ho kenyeletsoa Terrestrial TV), ho netefatsa 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 17 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-16 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-16 e ka aba tse 'nè tsa Quattro LNB 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.
Sehokelo sa fiber sa GLB3500M-16 se kenyelletsa GLB3500M-16T fiber optic transmitter le GLB3500M-16R fiber optic receiver. Ka CWDM lasers / photodiode le lerata le tlaase la RF e laolang potoloho ea taolo, e le 'ngoe ea GLB3500M-16T e ka fana ka RF ea boleng bo phahameng ho ea ho 32pcs GLB3500M-16R e amohelang optical e phahameng ka har'a sebaka sa 5Km fiber.
