GLB2000A-K Terr TV me te Fiber Optic Twin LNB
Whakaahuatanga Hua
GLB2000A amiorangi TV FTTH whatu LNB tahuri tohu whatu ki rua polarities RF mo te kotahi amiorangi kaiwhiwhi. Ma te mahi tahi me te Greatway GLB3500A-2T amiorangi TV muka whatu tuku, GLB2000A whakaputa te kounga teitei TV Terrestrial + Poutū / Whakapae RF tohu. Ka taea e tenei ftth LNB te huri i te tohu whakaputa Poutū (RHCP ranei) Whakapae (LHCP ranei) na te hiko 13V, 18V DC ranei mai i te kaiwhiwhi amiorangi.
Ko te LNB i nga wa katoa he iti te haruru Poraka, ka huri i te Ku Band 10.7GHz ~ 12.75GHz RF ranei C Band 3.7GHz ~ 4.2GHz RF ki 950MHz ~ 2150MHz Mēnā mo te kaiwhiwhi noho. 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 karu matarangi 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 runga i te 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 pouara 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 whai i te tauranga RF kotahi mai i te muka SM kotahi.
