GLB3500A-2R Twin Fiber Optic LNB

ʻO GLB3500A-2R satellite LHCP/RHCP FTTH Optical LNB he mea hoʻokipa fiber optic e hoʻololi ana i ka hōʻailona optical i RF no nā mea hoʻokipa ukali ʻelua. Ke hana nei me Greatway GLB3500A-2T satellite TV fiber optic transmitter, GLB3500A-2R outputs high quality Terrestrial TV+ LHCP a me Terrestrial TV + RHCP RF hōʻailona i hoʻokahi ʻohana me ʻelua mau mea hoʻokipa ukali. Hiki i kēia FTTH Twin LNB ke loaʻa i ʻelua mau pukana RF, hiki i kēlā me kēia awa RF ke hoʻololi i ka hōʻailona LHCP a i ʻole RHCP output e ka mana 13V a i ʻole 18V DC mai ka mea lawe ukali.

MauLNBʻo iaLauweNoiseBlaka, hoohuli Ku Band 10.7GHz~12.75GHz RF a C Band 3.7GHz~4.2GHz RF i 950MHz~2150MHz IF no noho hookipa. 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.

Loaʻa iā GLB3500A-2R ka koho 1310nm / 1490nm WDM no ka hana pū me GPON / EPON ONU i kekahi hihia FTTH, e hiki ai ke hoʻokomo i ka TV satellite ma luna o ka pūnaewele GPON / EPON.
