I-Fiber Optic LNB Dongle

Meyi 14, 2023, iGreatway Technology yamemezela ukukhulula i-GFD2000 Fiber Optic LNB Dongle. I-GFD2000 i-fiber optic LNB Dongle iyisamukeli se-TV esiyi-compact fibre optic esifakwe echwebeni le-RF lesathelayithi STB. Isebenza nge-Greatway GLB3500MT optical transmitter, i-GFD2000 LNB dongle iguqula isignali yokubona ibe yiSatellite RF. Inikwa amandla yi-13V/18V DC kusukela kusamukeli sesathelayithi, i-GFD2000 ikhipha ama-transponder wekhwalithi ephezulu wesathelayithi ngokuzuza idizayini eyisicaba. I-GFD2000 ine-MER yesathelayithi enhle kakhulu ngamandla okufaka aphansi kakhulu (afana -18dBm). Isihlungi esakhelwe ngaphakathi esingu-1550nm asifaki isignali engu-1490nm noma engu-1577nm OLT kusukela ku-GFD2000 kusistimu ye-GPON/XGPON FTTH.

I-GLB3500MT ingaguqula ubukhulu obungu-32UB isuka kusethelayithi eyodwa noma isathelayithi ezine ibe ifayibha engu-1550nm ngesiguquli sesathelayithi sangaphandle. 20dBm inguqulo yamandla aphezulu GLB3500MT-D20 ingashayela 512pcs GFD2000 LNB Dongles ngokuqondile. Lokhu kunikeza indlela engabizi kakhulu kubabhalisi abahlala ezindlini noma emphakathini ukuze babukele okuqukethwe okudumile okufana ne-BeIN, i-OSN njll. phezu kwe-STB ehlezi evamile noma isiqophi sokuhlala esimisiwe ngokufaka le dongle ye-LNB echwebeni layo le-RF. Ngenxa yesihlungi esakhelwe ngaphakathi esingu-1550nm, i-GFD2000 ingafakwa endaweni ye-RF yedekhoda ngqo ngisho noma obhalisile akanayo i-GPON/XGPON ONU.

I-GFD2000 LNB Dongle inika amandla noma iyiphi i-STB yesathelayithi ukuthi ixhunywe nenethiwekhi ye-PON. Ukusetshenziswa kwamandla okuphansi, ukuzwela okuphezulu kokubona, ipulaki nedizayini yokudlala kanye nokuvikelwa kwembobo ye-RF, lezi zici ezihamba phambili zimaka i-STB yesathelayithi enkathini ye-LNB dongle.

Itholakala e-Shenzhen, i-Greatway Technology iyi-RF phezu kwe-fiber transmission product design house kanye nefekthri kusukela ngo-2004, ihlinzeka ngesamukeli se-FTTH CATV, i-RFoG ONU yemodemu yekhebula le-ftth, isathelayithi eyodwa/I-Twin/Quatro LNB RF phezu kwe-GPON, amasathelayithi Amabili/Ane phezu kwefayibha eyodwa. isixhumanisi, Ibhethri ye-Super Capacitor, i-GPON ne-GPON+, i-EoC, i-1218MHz CATV optical transmitter kanye node optical, isigaba sokusakaza isixhumanisi se-fiber AV/ASI/SDI.
