GFH2000-K TV na Sat Fibre Optic LNB
Ibisobanuro ku bicuruzwa
GFH2000-K ni 45 ~ 2600MHz 1550nm fibre optique yakira hamwe nicyambu cya WDM kuri FTTH ONU.Nka fibre yibanze ya LNB, GFH2000-K ifite umurongo mugari LNB (300MHz ~ 2350MHz) cyangwa LNB isanzwe (950MHz ~ 2150MHz) + CATV RF band, ikorana na GWT3500S (CATV + Sat) fibre optique cyangwa GLB3500MT-D (Terr TV + Sat NIBA) fibre optique cyangwa imiyoboro yagutse.
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.
Nka optique ya optique ya LNB, GFH2000-K irashobora gukorana nundi muntu wa gatatu GPON ONU cyangwa 1270nm / 1577nm XGPON ONU cyangwa 1524 ~ 1544/1596 ~ 1599nm NGPON2 ONU, ugashyiramo amashusho meza cyane ya CATV + SAT abiyandikisha kuri FTTH utiriwe ukoresha interineti iyo ari yo yose. Umuyoboro mugari.
Ibindi biranga:
•Photodiode Yumurongo muremure kuri TV yo ku isi na Satelite TV RF.
•45MHz ~ 2600MHz (hepfo) Ibisohoka RF.
•1270nm / 1577nm Icyambu cyiza cya Bypass kuri XGPON ONU.
•1524 ~ 1544nm / 1596 ~ 1599nm icyambu cyambukiranya inzira kuri NGPON2 ONU.
•DC Imbaraga hamwe na optique yinjiza LED.
•Yigenga 10 ~ 18V DC amashanyarazi adahuza icyambu.
