GLB3500A-2R Twin Fiber Optic LNB

GLB3500A-2R satellite LHCP/RHCP FTTH Optical LNB ndi cholandira cha fiber optic chomwe chimatembenuza siginecha ya kuwala kukhala RF kwa olandila ma satellite opitilira awiri.Kugwira ntchito ndi Greatway GLB3500A-2T satellite TV fiber optic transmitter, GLB3500A-2R imatulutsa mawonekedwe apamwamba kwambiri a Terrestrial TV+ LHCP ndi Terrestrial TV + RHCP RF ku banja limodzi lokhala ndi ma satelayiti oposa awiri olandila.FTTH Twin LNB iyi imatha kukhala ndi zotulutsa ziwiri za RF, doko lililonse la RF limatha kusintha siginecha ya LHCP kapena RHCP ndi mphamvu ya 13V kapena 18V DC kuchokera ku cholandila satana.

WokhazikikaLNBndiLuwuNayiBloko, kutembenuza Ku Band 10.7GHz~12.75GHz RF kapena C Band 3.7GHz~4.2GHz RF kukhala 950MHz~2150MHz IF pakukhala wolandila.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

LNB yokhazikika imakhala ndi ma polarities ofukula kapena opingasa (13V/18V) ndi bandi yapamwamba kapena yotsika (0Hz kapena 22KHz).Pogwiritsa ntchito ukadaulo wa CWDM/DWDM, kuwala kwa LNB kumatha kukhala ndi doko la RF lothandizira DiSEqC.

GLB3500A-2R ili ndi 1310nm/1490nm WDM njira yogwirira ntchito limodzi ndi GPON/EPON ONU muzochitika zilizonse za FTTH, zomwe zimathandiza kuyika TV ya satana pa netiweki ya GPON/EPON.
