GLB3500E-2R FTTH LNB
Ibisobanuro ku bicuruzwa
GLB3500E-2R satelite TV FTTH Optical LNB ni fibre optique yakira fibre optique ihindura ibimenyetso bya optique muri RF kubantu bakira satelite bagera kuri 4 murugo rumwe. Gukorana na Greatway GLB3500E-2T satelite ya tereviziyo ya optique, GLB3500E-2R yubatswe muri moderi ya SatCR ikorana n’umuyoboro mugari wa RF, isohora imirongo 4 y’abakoresha icyogajuru ku cyambu kimwe cya SatCR RF ku bantu 4 badashobora kwakira icyogajuru.
Ibisanzwe LNB ni urusaku ruke, ruhindura 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.
GLB3500E-2R ifite 1310nm / 1490nm / 1550nm icyambu cya WDM cyo gukorana na GPON ONU mubisabwa byose FTTH, ituma ibyogajuru gakondo bya Quattro LNB byinjizwa muri sisitemu ya GPON.
Ibindi biranga:
•Photodiode Yumurongo muremure.
•SC / APC fibre yinjiza.
•Urwego rwiza rwa AGC: -6dBm ~ + 1dBm.
•Icyambu kimwe cya SatCR RF kubantu bagera kuri 4 badashobora kwakirwa bicara murugo rumwe.
•Sat RF Ban: 950 ~ 2150MHz.
•CE yemeye.
