GFH2000-K TV ndi Sat Fiber Optic LNB
Mafotokozedwe Akatundu
GFH2000-K ndi 45 ~ 2600MHz 1550nm fiber optic wolandila ndi doko la WDM kupita ku FTTH ONU.Monga maziko oyambira CHIKWANGWANI chamawonedwe LNB, GFH2000-K ali wideband LNB (300MHz ~2350MHz) kapena LNB nthawi zonse (950MHz ~ 2150MHz)+CATV RF magulu, imagwira ntchito ndi GWT3500S (CATV+Sat) fiber optic transmitter kapena GLB3500MT TV-D (Terr) Sat IF) fiber optic transmitter kapena wideband Optical transmitter.
LNB yanthawi zonse ndi Low Noise Block, yosinthira Ku Band 10.7GHz~12.75GHz RF kapena C Band 3.7GHz~4.2GHz RF kukhala 950MHz~2150MHz IF ya sat receiver.Pa SMATV pa fiber system, transmitter imodzi imatembenuza LNB IF kukhala CHIKWANGWANI.Pambuyo pa fiber optic amplifier ndi PON, chizindikiro cha optic chimagawidwa ku mabanja mazana kapena masauzande a FTTH.Panyumba iliyonse yokhala ndi chingwe cha fiber, cholandila chimodzi chowoneka bwino chimatembenuza ulusi kukhala Sat IF.Kulowetsa kwa Fiber kumatembenukira ku 950MHz ~ 2150MHz IF kutulutsa kwa wolandila.
Satellite Optical receiver imagwira ntchito yofanana ndi LNB wamba, ndi "virtual" LNB kunyumba.Satellite Optical receiver imatha kutchedwa Optical LNB kapena Fiber LNB.
LNB yokhazikika imayikidwa pa mbale moyang'ana kumwamba.Optical LNB imayikidwa kulikonse kunyumba komwe ulusi umapezeka.Zomwe zili mu LNB imodzi yokhazikika zitha kupangidwanso mpaka 500K Optical LNBs.
Monga universal kuwala LNB, GFH2000-K akhoza kugwira ntchito ndi wina aliyense chipani GPON ONU kapena 1270nm/1577nm XGPON ONU kapena 1524~1544/1596 ~ 1599nm NGPON2 ONU, kuyika yaikulu mkulu khalidwe kuwulutsa CAFTTH+ SAT mavidiyo olembetsa pa intaneti aliyense bandwidth.
Zina:
•High Linearity Photodiode ya Terrestrial TV ndi Satellite TV RF.
•45MHz ~ 2600MHz (kumunsi) Kutulutsa kwa RF.
•1270nm/1577nm Optical Bypass port kupita ku XGPON ONU mwina.
•1524 ~ 1544nm / 1596 ~ 1599nm yodutsa doko kupita ku NGPON2 ONU njira.
•DC Mphamvu ndi kuwala athandizira LED chizindikiro.
•Doko lodziyimira pawokha la 10 ~ 18V DC la adapter yamagetsi.
