GFH2000-K TV and Sat Fiber Optic LNB
GFH2000-K is 45~2600MHz 1550nm fiber optic receiver with WDM port to FTTH ONU. As a basic fiber optic LNB, GFH2000-K has wideband LNB (300MHz ~2350MHz) or regular LNB (950MHz~2150MHz)+CATV RF bands, it works with GWT3500S (CATV+Sat) fiber optic transmitter or GLB3500MT-D (Terr TV+ Sat IF) fiber optic transmitter or wideband optical transmitter.
Regular LNB is Low Noise Block, converting Ku Band 10.7GHz~12.75GHz RF or C Band 3.7GHz~4.2GHz RF to 950MHz~2150MHz IF for sat receiver. At SMATV over fiber system, one transmitter converts LNB IF to fiber. After fiber optic amplifier and PON, optic signal is distributed to hundreds or thousands of FTTH families. At each home with fiber cable, one optical receiver converts fiber to Sat IF. Fiber input turns to 950MHz~2150MHz IF output for sat receiver.
Satellite optical receiver plays the same role as regular LNB, it is a "virtual" LNB at home. Satellite optical receiver can be called as Optical LNB or Fiber LNB.
Regular LNB is installed at dish facing the sky. Optical LNB is installed anywhere in home where fiber is available. The contents of one regular LNB can be re-produced up to 500K optical LNBs.
As a universal optical LNB, GFH2000-K can work with any third party GPON ONU or 1270nm/1577nm XGPON ONU or 1524~1544/1596~1599nm NGPON2 ONU, inserting huge high quality broadcasting CATV+SAT videos to FTTH subscriber without consuming any internet bandwidth.
