GLB2000A-K Terr TV a me Fiber Optic Twin LNB
Hōʻike huahana
Hoʻololi ʻo GLB2000A satellite TV FTTH optical LNB i ka hōʻailona optical i ʻelua polarities RF no hoʻokahi mea lawe ukali. Ke hana nei me Greatway GLB3500A-2T satellite TV fiber optic transmitter, GLB2000A outputs high quality Terrestrial TV+ Vertical/Horizontal RF signal. Hiki i kēia ftth LNB ke hoʻololi i ka hōʻailona puka Vertical (a i ʻole RHCP) a i ʻole Horizontal (a i ʻole LHCP) e ka mana 13V a i ʻole 18V DC mai ka mea hoʻokipa ukali.
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 hoʻopaʻa uila uila 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 kūpaʻa a i ʻole paha (13V/18V) a me ka pūna 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 i ka port RF mai hoʻokahi fiber SM.

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 i ka port RF mai hoʻokahi fiber SM.
Loaʻa iā GLB2000A kahi koho 1310nm / 1490nm WDM no ka hana pū me GPON / EPON ONU i kekahi hihia FTTH, e hiki ai ke hoʻokomo i ka DTT + SAT ma luna o ka pūnaewele GPON / EPON.
Nā hiʻohiʻona ʻē aʻe:
•ʻO ka hale hoʻopaʻa ʻia i ka lapalapa ahi.
•Kiʻi Linearity Photodiode.
•SC/APC fiber komo.
•Laulā AGC Optical: -6dBm ~ +1dBm.
•Sat RF Bandwidth: 950MHz~2150MHz.
•Pāʻani RF TV Terrestrial: 174~806MHz.
•TV Terrestrial + Horizontal (LHCP)@18V DC from mea lawe ukali..
•TV Terrestrial + Vertical (RHCP)@13V DC mai ka mea lawe ukali.
•ʻO ke awa WDM koho i GPON ONU.
