Factory wholesale Lnb Octo Universal - GLB2000A-K Terr TV and Fiber Optic Twin LNB – Greatway

Product Description

GLB2000A satellite TV FTTH optical LNB converts optical signal into two polarities RF for one satellite receiver.  Working with Greatway GLB3500A-2T satellite TV fiber optic transmitter, GLB2000A outputs high quality Terrestrial TV+ Vertical/Horizontal RF signal.  This ftth LNB can switch Vertical (or RHCP) or Horizontal (or LHCP) output signal by the 13V or 18V DC power from satellite receiver.

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
• Regular LNB has vertical or horizontal polarities (13V/18V) and higher band or lower band (0Hz or 22KHz). By means of CWDM/DWDM technology, optical LNB can have the same function RF port from one SM fiber.
