GFH2000-K TV a me Sat Fiber Optic LNB
Hōʻike huahana
ʻO GFH2000-K ka 45 ~ 2600MHz 1550nm fiber optic receiver me WDM awa i FTTH ONU.Ma ke ʻano he LNB fiber optic maʻamau, loaʻa iā GFH2000-K ka wideband LNB (300MHz ~ 2350MHz) a i ʻole LNB maʻamau (950MHz ~ 2150MHz) + CATV RF band, hana ia me GWT3500S (CATV+Sat) fiber optic transmitter a i ʻole GLB3500MT-D (Terr TV+ Sat IF) mea hoʻolele optic fiber a i ʻole broadband optical transmitter.
ʻO ka LNB maʻamau ka haʻahaʻa haʻahaʻa haʻahaʻa, hoʻololi i ka Ku Band 10.7GHz ~ 12.75GHz RF a i ʻole C Band 3.7GHz ~ 4.2GHz RF i 950MHz ~ 2150MHz IF no ka mea hoʻokipa noho.Ma SMATV ma luna o ka ʻōnaehana fiber, hoʻololi kekahi transmitter i ka LNB IF i fiber.Ma hope o ka fiber optic amplifier a me PON, ua puʻunaue ʻia ka hōʻailona optic i nā haneli a i ʻole mau tausani o nā ʻohana FTTH.Ma kēlā me kēia hale me ke kaula fiber, hoʻokahi mea hoʻokipa optical e hoʻololi i ka fiber i Sat IF.Huli ka hoʻokomo fiber i 950MHz~2150MHz IF no ka mea hoʻokipa noho.
Hoʻokani like ka mea hoʻokipa optical satellite me ka LNB maʻamau, he LNB "virtual" ma ka home.Hiki ke kapa ʻia ʻo Optical LNB a i ʻole Fiber LNB.
Hoʻokomo ʻia ka LNB maʻamau ma ka pā e kū pono ana i ka lani.Hoʻokomo ʻia ʻo Optical LNB ma nā wahi āpau o ka home kahi e loaʻa ai ka fiber.Hiki ke hana hou ʻia nā mea i loko o hoʻokahi LNB maʻamau a hiki i 500K LNB optical.
Ma ke ʻano he LNB optical universal, hiki iā GFH2000-K ke hana me kekahi ʻaoʻao ʻekolu GPON ONU a i ʻole 1270nm / 1577nm XGPON ONU a i ʻole 1524 ~ 1544/1596 ~ 1599nm NGPON2 ONU, e hoʻokomo ana i nā wikiō hoʻolaha kiʻekiʻe kiʻekiʻe CATV + SAT i ka hoʻohana ʻana i nā wikiō FTTH me ka ʻole. bandwidth.
Nā hiʻohiʻona ʻē aʻe:
•ʻO Photodiode Linearity kiʻekiʻe no ka TV Terrestrial a me Satellite TV RF.
•45MHz~2600MHz (lalo) RF Hoʻopuka.
•1270nm/1577nm Optical Bypass awa i XGPON ONU koho.
•1524~1544nm/1596~1599nm bypass awa i NGPON2 ONU koho.
•ʻO ka mana DC a me ka hōʻailona LED komo optical.
•Kūʻokoʻa 10 ~ 18V DC mana hoʻopili mana.
