Ku ya 19 Mata 2021, Ikoranabuhanga rya Greatway ryatangaje ko risohora GWT3500S 1550nm optique yohereza optique, ifite fibre imwe hamwe n’ibisubizo bibiri bya RF: imwe kuri 45 ~ 806MHz 80ch igereranya CATV cyangwa DVB-C QAM cyangwa DVB-T indi yo kwinjiza 950 ~ 2150MHz . GWT3500S irashobora gutanga TV igereranya, TV ya DVB-C / T na TV ya satelite ya DVB-S / S2 kuri sisitemu iyo ari yo yose ya FTTH. Hamwe na power power optique amplifier, GWT3500S ituma FTTH MSO itanga TV igereranya, DTT cyangwa DVB-C, hamwe na videwo ya satelite yoherejwe na transmitter imwe gusa. Byinshi byamamaza TV RF kumutwe wa CATV bituruka kubayobora amashusho yaho, amashusho ya satelite yatoranijwe re-modulation hamwe nibisohoka kuri interineti QAM. Mubyukuri, ntabwo ari ubukungu guhindura TV zose za satelite kuri CATV niba icyogajuru nyamukuru gifite ibintu byinshi bizwi kuri TV. Nibyiza cyane gukwirakwiza ibimenyetso bya satelite hamwe na CATV RF. Hamwe na sisitemu nyinshi ya FTTH yohereza GPON muri serivisi ya interineti, umurongo wa CATV utera imbere wa RF urashobora kwaguka kuri 45 ~ 2150MHz, harimo na CATV na TV ya Satelite. Hifashishijwe tekinoroji ya DWDM, abashakashatsi ba Greatway Technology bakemuye iki kibazo cyagutse cya RF umurongo wohereza. GWT3500S ikorana na CATV RF hamwe na TV ya satelite itandukanye, itanga imikorere myiza ya RF kumurongo wa CATV hamwe nitsinda rya satelite. GWT3500S irashobora gutuma FTTH MSO itanga TV igereranya, serivisi za DVB-C / T / S icyarimwe mumurongo umwe muburyo bworoshye. Nyuma yubwinshi bwa videwo yo mu rwego rwo hejuru isakara kuri 1550nm idirishya rya optique, serivisi za interineti zifite umurongo mugari. GWT3500S irashobora gukorana na sisitemu ya GPON, XGPON, NGPON2 FTTH. Iherereye i Shenzhen, Ikoranabuhanga rya Greatway ni RF hejuru yinzu nogukora ibicuruzwa byoherejwe na fibre kuva 2004, itanga imashini ya FTTH CATV, RFoG ONU kuri modem ya kabili modem, icyogajuru kimwe / Twin / Quatro LNB RF hejuru ya GPON, Satelite ebyiri / enye hejuru ya fibre imwe Ihuza, 3224MHz Satelite Fibre Ihuza, GPON na GPON +, EoC, 1218MHz CATV itanga imiyoboro ya optique na node ya optique, itumanaho rya AV / ASI / SDI fibre.
