GLB3500M-4 Terr TV a me One Quattro LNB ma luna o ka fiber
Hōʻike huahana
ʻO GLB3500E-4R satellite TV FTTH Optical LNB he ʻelua-core fiber input optic receiver, e hoʻololi ana i ʻehā wideband RFs mai ʻelua mau ukali (e laʻa, Nilesat a me Arabsat) ma luna o nā hōʻailona fiber i hoʻokahi hua RF a hiki i 4 mau mea lawe ukali ma ka home hoʻokahi. Ke hana nei me 2pcs Greatway GLB3500E-2T satellite TV optical transmitters mai ʻelua fiber inputs, ua kūkulu ʻo GLB3500E-4R i loko o ka module SatCR e hoʻololi ana i ka wideband RF mai nā satelite ʻelua, e hoʻopuka ana i 4 mau mea hoʻohana ukali ma hoʻokahi awa SatCR RF no 4 unicable satellite receivers.
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 SMATV maʻamau ʻelua mau kaula RF mai ka hale o ka hale a hiki i nā multiswitch cascading, e lawelawe ana ma lalo o 100 mau mea kākau ma ka hale hoʻokahi. No nā satelite ʻelua SMATV ma luna o ka fiber, aia ʻo Greatway Technology iā GLB3500M-8 ma ke ʻano he FTTB solution a me GLB3500E-4R ma ke ʻano he FTTH solution. Pono ka hoʻonā FTTB e loaʻa iā STB satellite maʻamau, ʻoiai ʻo ka solution FTTH pono e loaʻa i ka satellite STB ke kākoʻo ʻole.
Loaʻa iā GLB3500E-4R 1310nm / 1490nm / 1550nm WDM koho awa no ka hana pū ʻana me GPON ONU ma kekahi noi FTTH, e hiki ai ke hoʻokomo ʻia nā mea LNB satellite piha i ka ʻōnaehana GPON.
Nā hiʻohiʻona ʻē aʻe:
•ʻO ka hale plastik paʻa.
•ʻElua mau mea hoʻokomo fiber SC/APC a me hoʻokahi puka RF.
•Kiʻi Linearity Photodiode.
•Laulā AGC Optical: -6dBm ~ +1dBm.
•Hoʻokahi awa SatCR RF a hiki i 4 mau mea hoʻokipa noho ʻole.
•Sat RF Band: 950~2150MHz.
•ʻO ke kelepona TV Terrestrial RF Bandwidth: 88~250MHz.
•Hoʻokō i nā kūlana EN50494+EN50607.
•ʻO ke awa WDM koho i GPON ONU.
•Koho: Hoʻokahi awa SatCR RF a hiki i 8 mau mea hoʻokipa noho ʻole.
