GLB3500M-8 Terr TV a me ʻelua Quattro LNB ma luna o ka fiber
Hōʻike huahana
GLB3500M-8he a8ch CWDM Satellite RF fiber loulou, hoʻouna8IFs mai2Quattro LNBs ma2ʻO nā kīʻaha Satellite like ʻole a me 1 TV RF terrestrial ma luna o hoʻokahi fiber SM i nā mea kākau inoa lehulehu. ʻO kēlā me kēia CWDM optical wavelength e lawe i hoʻokahi 950 ~ 2150MHz RF hōʻailona (a i ʻole 174 ~ 2150MHz, me Terrestrial TV), e hōʻoiaʻiʻo ana i ka hana RF maikaʻi loa a me ka hoʻokaʻawale ʻana i waena o nā polarities satellite.
Ua kaulana ʻo SMATV (Satellite Master Antenna TV) e hāʻawi i ka TV satelite a me ka TV terrestrial i nā mea kūʻai aku e noho ana ma nā hale a i ʻole ke kaiāulu. Hiki i ka SMATV kuʻuna ke puʻunaue i ka ʻike antenna master ma o ka multiswitch i nā mea hoʻokipa ukali ma luna o ke kaula coaxial. Ma muli o ka pohō kiʻekiʻe ma ke alapine satellite kiʻekiʻe, ʻoi aku ka liʻiliʻi o ka mamao o ke kelepona SMATV ma mua o 150 mika me ka mea hoʻonui pūnaewele IF. Pono nā ʻōnaehana ʻelua Quattro LNB SMATV maʻamau i nā kaula 9 RF mai ka hale o ka hale a hiki i nā multiswitchs cascading, e lawelawe ana ma lalo o 100 mau mea inoa ma ka hale hoʻokahi. Hiki iā GLB3500M-8 iā SMATV ma luna o ka fiber i nā hale a me nā mea kākau inoa. Me ka PLC fiber splitter a me ka cascading multiswitchs i kēlā me kēia hale, hiki i ka GLB3500M-8 ke puʻunaue i ʻelua Quattro LNB a me Terr TV i ka nui o nā mea kākau inoa 3200 i ke kaiāulu. ʻO kēia ka mea maʻamau hybrid fiber coaxial cable noi ma ka satellite TV.
ʻO ka loulou fiber GLB3500M-8 me GLB3500M-8T fiber optic transmitter a me GLB3500M-8R fiber optic receiver. Me ka CWDM lasers/photodiode a me ka haʻahaʻa haʻahaʻa RF loaʻa ka mana kaapuni, hoʻokahi GLB3500M-8T hiki ke hāʻawi i ka RF kiʻekiʻe i ka 32pcs GLB3500M-8R kiʻekiʻe loa i loko o ka mamao 5Km fiber.
