GLB3500M-8 Terr TV ndi Two Quattro LNBs pa fiber
Mafotokozedwe Akatundu
GLB3500M-8ndi a8ch CWDM Satellite RF fiber ulalo, kufalitsa8IFs kuchokera2Quattro LNBs pa2Zakudya za Satellite zosiyanasiyana ndi 1 terrestrial TV RF pa SM fiber imodzi kwa olembetsa angapo.Aliyense CWDM kuwala wavelength amanyamula 950 ~ 2150MHz RF chizindikiro (kapena 174 ~ 2150MHz, kuphatikizapo Terrestrial TV), kuonetsetsa RF ntchito bwino ndi kudzipatula pakati pa satellite polarities.
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.Makina awiri apawiri a Quattro LNB SMATV amafunikira zingwe 9 za RF kuchokera padenga la nyumba kupita kumalo osinthira osinthika, olembetsa osakwana 100 mnyumba imodzi yokha.GLB3500M-8 imathandizira SMATV pa fiber kupita ku nyumba zambiri ndi olembetsa.Pamodzi ndi PLC fiber splitter ndi cascading multiswitch munyumba iliyonse, GLB3500M-8 imatha kugawa ma Quattro LNB awiri ndi Terr TV mpaka olembetsa 3200 mdera lawo.Uwu ndi mawonekedwe a hybrid fiber coaxial cable pa satellite TV.
Ulalo wa fiber wa GLB3500M-8 umaphatikizapo GLB3500M-8T fiber optic transmitter ndi GLB3500M-8R fiber optic receiver.Ndi ma lasers a CWDM / photodiode ndi phokoso lochepa la RF kuwongolera dera, GLB3500M-8T imodzi imatha kupereka RF yapamwamba kwambiri mpaka 32pcs GLB3500M-8R optical receiver mkati mwa 5Km fiber mtunda.
