Ngo-Ephreli 19, 2021, iGreatway Technology yamemezela ukukhulula i-GWT3500S 1550nm optical transmitter, enokukhishwa kwefayibha eyodwa nokokufaka okubili kwe-RF: eyodwa nge-45~806MHz 80ch analog CATV noma i-DVB-C QAM noma i-DVB-T kanti enye i-950 ~ 2150MHz Satellite Input . 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. 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, onjiniyela be-Greatway Technology baxazulule le nkinga yokudluliselwa komugqa we-RF ebanzi. I-GWT3500S isebenzisana ne-CATV RF kanye nesathelayithi TV RF ngokuhlukana, iqinisekisa ukusebenza okungcono kakhulu kwe-RF ebhendi ye-CATV nebhendi yesathelayithi ngokulandelana. I-GWT3500S ingakwazi ukunika amandla i-FTTH MSO ukuthi inikeze i-analog TV, i-DVB-C/T/S amasevisi ngesikhathi esifanayo kunethiwekhi eyodwa 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. 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, 3224MHz Satellite Fiber Link, GPON kanye GPON+, EoC, 1218MHz CATV optical transmitter kanye node optical, isigaba sokusakaza AV/ASI/SDI isixhumanisi fiber.
