GLB3500E-2T Terr TV ndi Wideband LNB Optical Transmitter
Mafotokozedwe Akatundu
GLB3500E-2T fiber optic transmitter idapangidwa kuti izipereka zinthu zotsika kwambiri (monga Hot Bird 13E) ulusi kunyumba ndi kapena popanda GPON Efaneti service. Kugwira ntchito ndi wideband LNB monga Greatway GWB104G, GLB3500E-2T optical transmitter atembenuza satellite wideband Horizontal 300MHz ~2350MHz, wideband Vertical 300MHz ~ 2350MHz RF kuchokera ku mapasa amodzi LNB (zonse zomwe zili mu Quatter RF mumtundu umodzi wa TV imodzi) ndikusinthanso mphamvu zamapasa a LNB ndi 14V DC.
Direct Broadcasting Satellite (DBS) ndi Direct to Home (DTH) ndi njira zodziwika bwino zosangalalira pa TV padziko lonse lapansi. Satellite antenna, coaxial cable, splitter kapena multi-switcher ndi satellite receiver ndizofunikira. Komabe, kukhazikitsa antenna satana kungakhale kovuta kwa olembetsa omwe amakhala m'nyumba. SMATV (satellite mater antenna TV) ndi yankho labwino kuti anthu okhala mnyumbamo kapena ammudzi agawane mbale imodzi ya satellite ndi mlongoti wapa TV wapadziko lapansi. Ndi chingwe cha fiber, chizindikiro cha SMATV RF chikhoza kuperekedwa ku 30Km kutali kapena kugawidwa ku zipinda 32 mwachindunji, ku 320 kapena 3200 kapena 32000 nyumba kudzera pa GWA3530 fiber optic amplifier.
GLB3500E-2T optical transmitter ili ndi + 6dBm optical output, +17dBm output kapena +20dBm output, yothandizira 1x32 kapena 1x128 kapena 1x256 fiber kupita ku home Optical receiver (FTTH LNB) mwachindunji.
