GFH2000-K TV me te Sat Fiber Optic LNB
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 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 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.
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 nui ki te whakamahi i tetahi kaiohauru ipurangi me te kore he kaiohauru FTTH. hōkaiipurangi.
Ētahi atu āhuatanga:
•Te Whakaata Raina Raina teitei mo te TV Terrestrial me te TV Satellite RF.
•45MHz~2600MHz (whakararo) Putanga RF.
•1270nm/1577nm Optical Bypass tauranga ki XGPON ONU kōwhiringa.
•1524~1544nm/1596~1599nm bypass tauranga ki NGPON2 ONU kōwhiringa.
•DC Power me te tohu tohu LED whakaurunga whatu.
•Motuhake 10~18V DC tauranga urutau hiko.
