GLB3500M-3 Terr TV ndi One wideband LNB pa fiber
Mafotokozedwe Akatundu
GLB3500M-3 ndi modular CWDM burodibandi RF CHIKWANGWANI ulalo, kufalitsa awiri 290MHz ~ 2350MHz Satellite RF (yothandizira UK 290MHz ~ 2340MHz kapena Europe 300MHz ~ 2350MHz) ndi mmodzi 45MHz ~ 806MHz Terrestrial ulusi SM amalembetsa ulusi TV RF pa imodzi.Broadband RF ili pa 1530nm kapena 1550nm, RF yapadziko lapansi ya TV ili pa 1570nm.Pali CHIKWANGWANI chamawonedwe CWDM mux kapena demux chipangizo pa chopatsira kuwala kapena kulandira kuzindikira ulusi umodzi kufala.
SMATV (Satellite Master Antenna TV) ndiyotchuka popereka TV yapa satellite ndi TV yapadziko lapansi kwa olembetsa omwe amakhala m'nyumba kapena mdera.Traditional SMATV imatha kugawa zomwe zili mu mlongoti kudzera pa multiswitch kupita ku zolandila satana pa chingwe cha coaxial.Chifukwa chakutayika kwakukulu pama frequency apamwamba a satellite, mtunda wa chingwe cha SMATV ndi wosakwana mita 150 ngakhale ndi amplifier ya IF pa intaneti.Mosiyana wamba Quattro LNB SMATV dongosolo, wideband LNB SMATV dongosolo ali theka zolumikizira RF ndi theka manambala chingwe, amene amapulumutsa mtengo kufala.Pambuyo pa fiber ku nyumbayi, wideband SMATV Optical receiver iyenera kugwira ntchito ndi dCSS multiswitch kuti ikhale ndi RF imodzi yotulutsa ndi 32 ogwiritsira ntchito, pomwe gulu lirilonse la olembetsa a STB a satana.Ulusi umodzi wopita ku nyumbayo ndi chingwe chimodzi cha coaxial kwa ogwiritsa ntchito ambiri mnyumbamo chimapangitsa kukhazikitsa ndi kukonza chingwe kukhala kosavuta.
GLB3500M-3 fiber ulalo umaphatikizapo GLB3500M-3T kuwala transmitter ndi GLB3500M-3R kuwala wolandila.Ndi ma lasers a CWDM / photodiode ndi phokoso lochepa la RF kuwongolera dera, GLB3500M-3T imodzi imatha kupereka RF yapamwamba kwambiri mpaka 32pcs GLB3500M-3R optic receiver mwachindunji.
Zina:
• Nyumba za aluminiyamu zolimba.
• 3 yodziyimira payokha burodibandi RF pa kufala SM CHIKWANGWANI.
• Bandiwifi iliyonse ya RF: wideband LNB 290~2350MHz kapena 45~806MHz.
• High Linearity Photodiode.
• Phokoso lochepa la RF Gain Control circuit.
