GLB3500E-2R FTTH LNB

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.

Loaʻa i ka LNB maʻamau nā polarities kūʻokoʻa a i ʻole paha (13V/18V) a me ka pahu kiʻekiʻe a i ʻole ka pahu haʻahaʻa (0Hz a i ʻole 22KHz). Ma o ka ʻenehana CWDM/DWDM, hiki i ka LNB optical ke hana like RF awa e kākoʻo ana iā DiSEqC.
