ʻApelila 19, 2021, ua hoʻolaha ʻo Greatway Technology i ka hoʻokuʻu ʻana i ka GWT3500S 1550nm optical transmitter, nona hoʻokahi fiber output a ʻelua RF inputs: hoʻokahi no 45 ~ 806MHz 80ch analog CATV a i ʻole DVB-C QAM a i ʻole DVB-T a ʻo kekahi no 950 ~ 2150MHz Satellite Input. .Hiki iā GWT3500S ke hāʻawi i ka TV analog, DVB-C/T TV a me DVB-S/S2 satellite TV ma luna o kekahi ʻōnaehana FTTH.Me ka mana kiʻekiʻe optical amplifier, GWT3500S hiki iā FTTH MSO ke hāʻawi ana i ka analog TV, DTT a i ʻole DVB-C, a me ke wikiō ukali ola mai hoʻokahi mea hoʻolele optical.ʻO ka hapa nui o nā RF TV hoʻolaha ma CATV poʻo mai nā modulator wikiō kūloko, koho hou ʻana i ka wikiō satellite a me ka hoʻopuka pūnaewele QAM.ʻO ka ʻoiaʻiʻo, ʻaʻole kūpono ke hoʻololi i nā TV satellite āpau i CATV inā he nui nā ʻike TV kaulana i ka satellite nui.ʻOi aku ka maikaʻi o ka hāʻawi ʻana i ka hōʻailona satellite me CATV RF.Me ka ʻoi aku ka nui o ka ʻōnaehana FTTH i ka GPON no ka lawelawe pūnaewele, hiki ke hoʻonui ʻia ka bandwidth CATV mua RF i 45 ~ 2150MHz, me ka hoʻolaha hoʻolaha kiʻekiʻe kiʻekiʻe CATV a me ka TV Satellite.Ma o ka ʻenehana DWDM, ua hoʻoponopono nā mea ʻenekinia Greatway Technology i kēia pilikia broadband RF linear transmission.Hoʻokaʻawale ʻo GWT3500S me CATV RF a me satellite TV RF ʻokoʻa, e hōʻoia ana i ka hana RF maikaʻi loa ma ka hui CATV a me ka hui ukali.Hiki iā GWT3500S ke hiki iā FTTH MSO ke hāʻawi i ka TV analog, nā lawelawe DVB-C/T/S i ka manawa like ma kahi pūnaewele ma kahi ala maʻalahi.Ma hope o ka nui o nā wikiō kiʻekiʻe e hoʻolaha ana ma 1550nm puka aniani, ʻoi aku ka maikaʻi o nā lawelawe pūnaewele.Hiki iā GWT3500S ke hana me GPON, XGPON, NGPON2 FTTH pūnaewele.Aia ma Shenzhen, Greatway Technology he RF ma luna o ka fiber transmission huahana hoʻolālā hale a me ka hale hana mai 2004, e hāʻawi ana i ka mea hoʻokipa FTTH CATV, RFoG ONU no ka ftth cable modem, satellite single / Twin / Quatro LNB RF ma luna o GPON, ʻElua / ʻEhā mau satellite ma luna o hoʻokahi fiber. loulou, 3224MHz Satellite Fiber Link, GPON a me GPON +, EoC, 1218MHz CATV ka mea hoʻolele uila a me ka node optical, ka papa hoʻolaha AV / ASI / SDI fiber link.
