GLB3500E-2R FTTH LNB

Nā hiʻohiʻona:

•ʻO ka hale alumini die-cast paʻakikī.

•Laulā AGC Optical: -6dBm ~ +1dBm.

•Hoʻokahi hoʻokomo SC, koho ONU awa a hoʻokahi RF puka.

•SatCR RF no 4pcs uncable sat receivers.

•Hoʻokō i nā kūlana EN50494+EN50607.

•ʻO ke kelepona TV Terrestrial RF Bandwidth: 88~250MHz.

•Ke hana nei me GLB3500E-2T transmitter.

•ʻO ke awa WDM koho i GPON ONU.

ʻO GLB3500E-2R satellite TV FTTH Optical LNB kahi mea hoʻokipa fiber optic e hoʻohuli ana i ka hōʻailona optical i RF a hiki i 4 mau mea hoʻokipa ukali ma ka home hoʻokahi.Ke hana nei me Greatway GLB3500E-2T satellite TV optical transmitter, ua kūkulu ʻo GLB3500E-2R i ka module SatCR e pili ana i ka wideband satellite RF, hoʻopuka i 4 mau mea hoʻohana ukali ma hoʻokahi awa SatCR RF no 4 uncable satellite receivers.

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.

Loaʻa iā GLB3500E-2R 1310nm / 1490nm / 1550nm WDM koho awa no ka hana pū ʻana me GPON ONU ma kekahi noi FTTH, kahi e hiki ai ke hoʻokomo ʻia nā mea maʻamau satellite Quattro LNB i loko o ka ʻōnaehana GPON.
