GLB3500A-2R Twin Fiber Optic LNB
Whakaahuatanga Hua
GLB3500A-2R amiorangi LHCP/RHCP FTTH Optical LNB he kaikawe muka whatu huri tohu whatu ki RF mo neke atu i te rua nga kaiwhiwhi amiorangi. Ma te mahi tahi me te Greatway GLB3500A-2T pouaka whakaata pouaka whakaata muka, ka whakaputahia e GLB3500A-2R te kounga teitei TV Terrestrial TV + LHCP me te TV Terrestrial + RHCP RF tohu ki tetahi whanau me te neke atu i te rua nga kaiwhiwhi amiorangi. Ka taea e tenei FTTH Twin LNB nga putanga RF e rua, ka taea e ia tauranga RF te huri i te tohu whakaputa LHCP, RHCP ranei na te mana 13V, 18V DC ranei mai i te kaiwhiwhi amiorangi.
TonuLNBkoLaueNoiseBmaukati, tahuri Ku Band 10.7GHz ~ 12.75GHz RF ranei C Band 3.7GHz ~ 4.2GHz RF ki 950MHz ~ 2150MHz IF mo noho kaiwhiwhi. I SMATV i runga i te punaha muka, ka huri tetahi kaiwhakawhiti i te LNB IF ki te muka. I muri i te whakakaha muka whatu me te PON, ka tohatohahia te tohu optic ki nga rau mano tini ranei o nga whanau FTTH. I ia kaainga me te taura muka, kotahi te kaikawe whatu ka huri te muka ki te Sat IF. Ka huri te whakauru muka ki te 950MHz~2150MHz IF te whakaputanga mo te kaiwhiwhi noho.
He rite tonu te mahi a te kaikawe ahuru mariko ki te LNB auau, he LNB "mariko" i te kainga. Ka taea te kiia ko te kaiwhakawhiwhi whatu Satellite hei Optical LNB, Fiber LNB ranei.
Ka whakanohohia te LNB ki nga rihi e anga atu ana ki te rangi. Ka whakauruhia te LNB Optical ki nga waahi katoa o te kaainga kei te waatea te muka. Ko nga ihirangi o tetahi LNB auau ka taea te hanga ano ki te 500K LNB whatu
Ko te LNB o ia te wa he polarities poutū, whakapae ranei (13V/18V) me te roopu teitei ake, te roopu raro ranei (0Hz, 22KHz ranei). Ma te hangarau CWDM/DWDM, ka taea e te LNB whatu te mahi kotahi te tauranga RF e tautoko ana i te DiSEqC.
Ko te GLB3500A-2R he whiringa 1310nm / 1490nm WDM mo te mahi tahi me te GPON / EPON ONU i roto i tetahi keehi FTTH, e taea ai te whakauru i te pouaka whakaata amiorangi i runga i te whatunga GPON / EPON.
