Ngomhla we-19 kuTshazimpuzi, ngo-2021, iGreatway Technology yabhengeza ukukhulula i-GWT3500S 1550nm i-optical transmitter, enemveliso yefayibha enye kunye neegalelo ezimbini zeRF: enye i45~806MHz 80ch analog CATV okanye DVB-C QAM okanye DVB-T kunye nenye ye950 ~ 2150MHz Satellite Input. . I-GWT3500S inokuhambisa iTV ye-analog, i-DVB-C/T TV kunye ne-DVB-S/S2 iTV yesathelayithi phezu kwayo nayiphi na inkqubo yeFTTH. Kunye ne-amplifier yamandla aphezulu, i-GWT3500S yenza ukuba i-FTTH MSO ibonelele nge-analog TV, i-DTT okanye i-DVB-C, kunye nevidiyo yesathelayithi ephilayo evela kwisidluliseli nje esinye. Uninzi lwee-RF zosasazo zeTV kwi-CATV headend zisuka kwiimodyuli zevidiyo zasekhaya, uhlengahlengiso olukhethiweyo lwevidiyo yesathelayithi kunye nemveliso ye-intanethi ye-QAM. Enyanisweni, akukho qoqosho ukuguqula yonke i-TV yesathelayithi ibe yi-CATV ukuba i-satellite engundoqo inemixholo emininzi ye-TV eyaziwayo. Kusebenza kakuhle ngakumbi ukusasaza umqondiso wesathelayithi kunye neCATV RF. Ngenkqubo ye-FTTH engakumbi yokufaka i-GPON yenkonzo ye-intanethi, i-CATV yangaphambili ye-RF bandwidth inokwandiswa ukuya kuma-45 ~ 2150MHz, kubandakanywa nosasazo oluphezulu olutyebileyo lwe-CATV kunye ne-Satellite TV. Ngokusebenzisa itekhnoloji ye-DWDM, iinjineli ze-Greatway Technology zayisombulula le ngxaki yothumelo lwe-RF olubanzi. I-GWT3500S isebenzisana ne-CATV RF kunye ne-satellite TV RF ngokwahlukeneyo, iqinisekisa ukusebenza kakuhle kweRF kwibhendi yeCATV kunye nebhendi yesathelayithi ngokulandelelanayo. I-GWT3500S inokwenza i-FTTH MSO ibonelele nge-analog TV, iinkonzo ze-DVB-C/T/S ngaxeshanye kwinethiwekhi enye ngeyona ndlela ilula. Emva kokuba inani elikhulu leevidiyo ezikumgangatho ophezulu zisasazwa kwifestile ye-1550nm optical, iinkonzo ze-Intanethi zine-bandwidth esebenzayo ngakumbi. I-GWT3500S inokusebenza neGPON, XGPON, NGPON2 FTTH inkqubo. Ifumaneka e-Shenzhen, i-Greatway Technology yi-RF phezu kwe-fiber yokuhanjiswa kwemveliso yoyilo lwendlu kunye nomzi-mveliso ukususela ngo-2004, inikezela nge-FTTH CATV receiver, RFoG ONU ye-ftth cable modem, i-satellite single / Twin / Quatro LNB RF phezu kwe-GPON, iisathelayithi ezimbini / ezine phezu kwefayibha enye. ikhonkco, i-3224MHz iSatellite Fiber Link, iGPON kunye neGPON +, i-EoC, i-1218MHz i-CATV ye-transmitter ebonakalayo kunye ne-node optical, iklasi yokusasaza i-AV / ASI / SDI ikhonkco yefiber.
