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.
