GLB3500A-2R Twin Fibre Optic LNB

GLB3500A-2R icyogajuru LHCP / RHCP FTTH Optical LNB ni fibre optique yakira ibimenyetso bya optique muri RF kubakira satelite zirenga ebyiri. Gukorana na Greatway GLB3500A-2T satelite ya fibre optique yohereza, GLB3500A-2R isohora televiziyo nziza yo ku isi + LHCP na TV yo ku isi + RHCP RF ikimenyetso ku muryango umwe ufite imashini zirenga ebyiri. Iyi FTTH Twin LNB irashobora kugira ibisohoka bibiri bya RF, buri cyambu cya RF gishobora guhindura ibimenyetso bya LHCP cyangwa RHCP byerekana ingufu za 13V cyangwa 18V DC bivuye mubakira ibyogajuru.

IbisanzweLNBniLowNoiseBgufunga, guhindura Ku Band 10.7GHz ~ 12.75GHz RF cyangwa C Band 3.7GHz ~ 4.2GHz RF kuri 950MHz ~ 2150MHz NIBA kubakira bicaye. Kuri SMATV hejuru ya fibre sisitemu, transmitter imwe ihindura LNB NIBA fibre. Nyuma ya fibre optique amplifier na PON, ibimenyetso bya optique bigabanywa mumiryango amagana cyangwa ibihumbi. Kuri buri rugo rufite umugozi wa fibre, imashini imwe ya optique ihindura fibre kuri Sat NIBA. Fibre yinjiza ihinduka 950MHz ~ 2150MHz NIBA ibisohoka kubakira.

Satelite optique yakira ifite uruhare runini nka LNB isanzwe, ni "Virtual" LNB murugo. Satelite optique yakira irashobora kwitwa Optical LNB cyangwa Fibre LNB.

LNB isanzwe yashyizwe kumasahani areba ikirere. Optical LNB yashyizwe ahantu hose murugo ahari fibre. Ibiri muri LNB imwe isanzwe irashobora kongera kubyara kugeza kuri 500K optique ya LNBs

LNB isanzwe ifite polarite ihagaritse cyangwa itambitse (13V / 18V) hamwe na bande yo hejuru cyangwa bande yo hasi (0Hz cyangwa 22KHz). Hifashishijwe tekinoroji ya CWDM / DWDM, optique LNB irashobora kugira imikorere imwe icyambu cya RF gishyigikira DiSEqC.

GLB3500A-2R ifite 1310nm / 1490nm WDM yo gukorana na GPON / EPON ONU muburyo ubwo aribwo bwose FTTH, ituma winjiza TV ya satelite kumurongo wa GPON / EPON.
