I-GLB3500E-2T Terr TV kanye ne-Wideband LNB Optical Transmitter
Incazelo Yomkhiqizo
I-GLB3500E-2T i-fiber optic transmitter yakhelwe ukuletha okuqukethwe kwe-transponder okuminyanisayo (okufana ne-Hot Bird 13E) ifayibha ekhaya ngesevisi ye-GPON Ethernet noma ngaphandle kwayo. Isebenza nge-wideband LNB efana ne-Greatway GWB104G, i-GLB3500E-2T i-optical transmitter iguqula i-satellite wideband Horizontal 300MHz ~2350MHz, i-wideband Vertical Vertical 300MHz~2350MHz RF isuka kumawele e-LNB (okuqukethwe okuphelele kwe-Quatter RF okuphumayo kwe-TV eyodwa ibe yimodi eyodwa ye-TV eyodwa) ngenkathi ihlehla inika amandla amawele e-LNB nge-14V DC.
I-Direct Broadcasting Satellite (DBS) kanye ne-Direct to Home (DTH) kuyindlela edume kakhulu yokujabulela i-TV yesathelayithi emhlabeni wonke. I-antenna yesathelayithi, intambo ye-coaxial, i-splitter noma i-multi-switcher kanye nesamukeli sesathelayithi ziyadingeka. Kodwa-ke, ukufakwa kwe-antenna yesathelayithi kungase kube nzima kubabhalisi abahlala ezindlini. I-SMATV (i-satellite mater antenna TV) iyisixazululo esihle sokuthi abantu abahlala esakhiweni noma emphakathini babelane ngesitsha sesathelayithi esisodwa kanye nothi lwe-TV yasemhlabeni. Ngekhebula le-fiber, isignali ye-SMATV RF ingalethwa ku-30Km kude noma isatshalaliswe ezindlini ezingama-32 ngokuqondile, ezindlini ezingu-320 noma ezingu-3200 noma ezingu-32000 nge-GWA3530 fiber optic amplifier.
I-GLB3500E-2T i-optical transmitter ine-+6dBm okukhiphayo okuphumayo, +17dBm okukhiphayo noma +20dBm okukhiphayo, okusekela u-1x32 noma 1x128 noma 1x256 fiber kumamukeli optical wasekhaya (FTTH LNB) ngokuqondile.
