GFD2000 LNB Dongle
Product Description
GFD2000 fiber optic LNB Dongle ndeye compact satellite TV fiber optic inogamuchira yakaiswa paRF port yesatellite STB. Kushanda neGreatway GLB3500MT optical transmitter, GFD2000 LNB dongle inoshandura chiratidzo chemaziso kuita Satellite RF. Inofambiswa neiyo 13V/18V DC kubva kune satellite inogamuchira, GFD2000 inoburitsa emhando yepamusoro setiraiti transponders nekuwana yakatsetseka dhizaini. GFD2000 ine yakanakisa setiraiti MER payakanyanya kuderera optical yekupinza simba (senge -18dBm).
Yakananga Nhepfenyuro Satellite (DBS) uye Yakananga Kumba (DTH) ndiyo inonyanya kufarirwa nzira yekunakidzwa nesatellite TV pasi rese. Kuti uzviite, satellite antenna, coaxial tambo, splitter kana multi-switcher uye satellite inogamuchira inodiwa. Nekudaro, kuisa satellite antenna kunogona kunetsa kune vanyoreri vanogara mudzimba. SMATV (satellite mater antenna TV) mhinduro yakanaka kune vanhu vanogara muchivakwa kana nharaunda kuti vagovane imwe setiraiti dish uye terrestrial TV antenna. Iine fiber tambo, SMATV RF siginecha inogona kuendeswa ku30Km kure kana kugoverwa kudzimba makumi matatu nembiri zvakananga, ku320 kana 3200 kana 32000 dzimba kuburikidza neGWA3530 fiber optic amplifier.
GLB3500MT inogona kushandura yakanyanya 32UB kubva kune imwe satellite kana mana satellite kuita 1550nm fiber kuburikidza nekunze setiraiti inoshandura. 20dBm high power version GLB3500MT-D20 inogona kutyaira 512pcs GFD2000 LNB Dongles zvakananga. Izvi zvinopa nzira isingadhure kune vanonyoresa vanogara mudzimba kana munharaunda kuti vaone zvirimo zvine mukurumbira zvakaita seBeIN, OSN nezvimwe. pamusoro peiyo STB yakagara yakagara kana iyo yakagadzwa yakagara decoder nekuisa LNB dongle pachiteshi cheRF. Nekuda kweiyo yakavakirwa-mukati 1550nm sefa, GFD2000 inogona kuisirwa pane sat decoder RF port zvakananga kunyangwe munyoreri asina GPON/XGPON ONU.
