IINKCUKACHA ZEMVELISO

Ingcaciso yeMveliso

I-GWT3500S yimodyuli ethe ngqo ye-1550nm DFB i-laser transmitter yokusabalalisa ifayibha exineneyo. I-GWT3500S inemveliso yefayibha enye kunye namagalelo eRF amabini: enye i45~806MHz 80ch analog CATV okanye DVB-C QAM okanye DVB-T kunye nezinye 950 ~ 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. Ngeteknoloji ye-DWDM, i-GWT3500S isebenza ne-CATV RF kunye ne-satellite TV RF ngokwahlukeneyo, iqinisekisa ukusebenza kakuhle kweRF kwibhendi yeCATV kunye nebhendi yesathelayithi ngokulandelelanayo.

I-GWT3500S ibonelela nge-analog TV, iinkonzo ze-DVB-C/T/S 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.
