I-GLB3500A-2T Terr TV kanye ne-Twin LNB Optical Transmitter
Incazelo Yomkhiqizo
I-GWT3500S iyi-modulation eqondile ye-1550nm DFB laser transmitter yokusabalalisa i-fiber dense. I-GWT3500S inokukhishwa kwefayibha eyodwa nokokufaka okubili kwe-RF: eyodwa engu-45~806MHz 80ch analog CATV noma i-DVB-C QAM noma i-DVB-T kanye nokunye okokufaka kwesathelayithi okungu-950~2150MHz. I-GWT3500S ingaletha i-analog TV, i-DVB-C/T TV kanye ne-DVB-S/S2 TV yesathelayithi nganoma iyiphi isistimu ye-FTTH. Ihlangene ne-amplifier yamandla aphezulu, i-GWT3500S inika amandla i-FTTH MSO enikeza i-analog TV, i-DTT noma i-DVB-C, kanye nevidiyo yesathelayithi ebukhoma evela kumthumeli wokubona owodwa nje.
I-GWT3500S inikeza i-analog TV, i-DVB-C/T/S ngamasevisi ngendlela elula. Ngemuva kokuthi inani elikhulu lamavidiyo ekhwalithi ephezulu lisakazwa efasiteleni le-optical 1550nm, izinsiza ze-inthanethi ziba nomkhawulokudonsa osebenza kangcono. I-GWT3500S ingasebenza ne-GPON, XGPON, NGPON2 FTTH uhlelo.
Ama-TV amaningi asakaza ama-TV esihlokweni se-CATV avela kumamojula wevidiyo endawo, ukushintshwa kwevidiyo yesathelayithi ekhethiwe kanye nokuphuma kwe-inthanethi kwe-QAM. Eqinisweni, akukhona ukonga ukuguqula yonke i-TV yesathelayithi ibe yi-CATV uma isathelayithi eyinhloko inokuqukethwe okuningi kwe-TV okudumile. Kusebenza kahle kakhulu ukusabalalisa isignali yesathelayithi kanye ne-CATV RF. Ngohlelo oluningi lwe-FTTH olukhipha i-GPON yesevisi ye-inthanethi, umkhawulokudonsa we-RF ovamile we-CATV unganwetshwa ube ngu-45~2150MHz, okuhlanganisa ukusakaza okucebile kwekhwalithi ephezulu i-CATV ne-Satellite TV. Ngobuchwepheshe be-DWDM, i-GWT3500S isebenzisana ne-CATV RF kanye nesathelayithi TV RF ngokuhlukana, iqinisekisa ukusebenza okungcono kakhulu kwe-RF ebhendi ye-CATV kanye nebhendi yesathelayithi ngokulandelana.
