WHAKAMAHI HUA

Whakaahuatanga Hua

GFH2000-K ko 45~2600MHz 1550nm muka whatu kaiwhiwhi ki WDM tauranga ki FTTH ONU.Ka rite ki te LNB muka whatu taketake, GFH2000-K he wideband LNB (300MHz ~ 2350MHz) ranei LNB auau (950MHz~2150MHz)+CATV RF ropu, mahi reira ki GWT3500S (CATV+Sat) muka whatu tuku GLB3500MT-D ranei (Terr TV+ Sat IF) te tuku muka whatu, te arai whanui ranei.

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 te 950MHz ~ 2150MHz IF mo te kaiwhiwhi noho.I te 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 kainga 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 putanga 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 i ia wa ki 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.

Hei LNB whatu ao, ka taea e GFH2000-K te mahi tahi me tetahi GPON ONU tuatoru, 1270nm / 1577nm XGPON ONU ranei 1524 ~ 1544 / 1596 ~ 1599nm NGPON2 ONU, te whakauru i nga riipene whakaata CATV + SAT he nui te kounga teitei ki te whakamahi i tetahi kaiohauru ipurangi me te kore e pau i te FTTH. hōkaiipurangi.
