Haddii hal dayax-gacmeed uu leeyahay transponders qani ah, transponders-yadu waxay ku yaalaan laba geesood: Vertical and Horizontal or Left Hand Circular Polarity (LHCP) iyo Hand Circular Polarity (RHCP). Qaadaha dayax-gacmeedka ee joogtada ah wuxuu akhrin karaa xawaaraha RF ee 950 ~ 2150MHz. Waxaa jira ugu badnaan 32 transponders laga bilaabo 950MHz ilaa 2150MHz.
Twin LNB ayaa laga yaabaa inay u magacawday soo noqnoqda LO ee dayax gacmeedka MSO. Labada wax soo saar ee RF waa Vertical (RHCP) iyo Horizontal (LHCP), mid kastaa wuxuu leeyahay xajmiga xajmiga 950 ~ 2150MHz. Haddii wadarta guud ee dayax gacmeedku ka yar yahay 64, waxaan isticmaali karnaa xalka soo socda si aan ugu qaybino waxa ku jira dayax-gacmeedka kumanaan guri iyada oo loo marayo fiber.
Sawirka kore, GLB3500A-2T gudbiyaha indhaha ayaa u beddelaya LNB RFs mataano ah iyo TV-ga dhulka (174 ~ 700MHz) RF hal 1550nm fiber hal saqaf oo dhismo ah. Wax soo saarka indhaha eeGLB3500A-2Twaxay si toos ah u wadi kartaa 32pcs qalabyada indhaha ee PLC fiber splitter, halkaas oo mid ka mid ahGLB2000Aqaataha indhaha waxa uu bixiyaa signalada satalaytka iyo Terr TV hal STB iyo TV hal guri,GLB3500A-2WRsoo dhaweynta indhaha waxay taageertaa hal deked oo Terr TV ah oo loogu talagalay TV-yo badan iyo 4 fadhiyey STB oo hal guri ah. Haddii nambarka macaamiishu uu ka badan yahay boqollaal ama kun oo bulshada dhexdeeda ah ama magaalada dhexdeeda, waa in aan lahaan doonaa hal cod-weyneeye GWA3530 ka dib GLB3500A-2T gudbiyaha indhaha.GWA3530Amplifier indhaha ayaa leh 8 ama 16 ama 32 ama 64 deked, deked kastaa waxay wadi kartaa 16 ama 32 ama 64 qalabyada indhaha. Si kale haddii loo dhigo, GWA3530 waxay ku kaxaysan kartaa 1024 aaladaha indhaha ama 2048 cod-qaadayaasha indhaha ama 4096 qaataha indhaha ee masaafo dhan 20Km. Deked gelinta OLT ee ikhtiyaarka ah, GWA3530 waxay gelin kartaa satellite TV RF isla fiber-ka GPON ama shabakadda XGPON.
Faa'iidooyinka TV-ga satellite-ka ee FTTH:
- Hal saxan oo loogu talagalay 32 macaamiil ama kumanaan macaamiil ah
- Tayada calaamada dayax-gacmeedka oo ka wanaagsan terminal kasta oo fiber ah
- Terminalka Fiber-ku waa sahlan tahay in lagu rakibo 5 daqiiqo gudaheed iyadoo la adeegsanayo naqshadeynta "plug and play".
- Qaadashada dayax-gacmeedka joogtada ah
Haddii ay jiraan in ka badan 32 transponders dayax-gacmeed kasta oo ku jira polarity dayax-gacmeedka, qaybta hoose iyo qaybta sare (oo ka hooseysa 22KHz tone) ayaa la soo bandhigay si ay ula kulmaan satalaytka qaataha caadiga ah ee 950MHz ~ 2150MHz. Twin wideband LNBGWB104Gwuxuu leeyahay 10.4GHz LO soo noqnoqda iyo xadiga soosaarka RF ee 300MHz ~ 2350MHz, ie, wideband Vertical RF waxay u dhigantaa Vertical Hoose (VL) iyo Vertical Higher (VH) ). Si kastaba ha ahaatee, bandwidth RF wideband waa ka baxsan bandwidth RF ee dayax-gacmeedka, waxaan u baahannahay Digital Channel Satellite Switcher (dCSS) chip si loogu badalo ballaaran RF galay kala duwan ee satalayt qaataha. Intaa waxaa dheer, qaataha dayax-gacmeedku waa inuu taageeraa heerka aan la isticmaali karin.
