Abriil 19, 2021, Greatway Technology ayaa ku dhawaaqday sii deynta GWT3500S 1550nm gudbiyaha indhaha, kaas oo leh hal wax soo saar fiber ah iyo laba qalab oo RF ah: mid loogu talagalay 45 ~ 806MHz 80ch analog CATV ama DVB-C QAM ama DVB-T iyo kan kale ee 950 ~ 2150MHz . GWT3500S waxay keeni kartaa TV-ga analogga ah, DVB-C/T TV iyo DVB-S/S2 satellite TV nidaam kasta oo FTTH ah. Iyada oo ay weheliso cod-weyneeye sare oo awood sare leh, GWT3500S waxa ay awood u siinaysaa FTTH MSO oo bixisa TV-ga analoogga ah, DTT ama DVB-C, iyo muuqaalka dayax-gacmeedka tooska ah ee hal gudbiye indhaha ah. Inta badan baahinta TV-yada RF-yada ee ciwaanka CATV waxay ka yimaaddaan modulators video-ga maxalliga ah, dib-u-habaynta muuqaalka dayax-gacmeedka ee la doortay iyo soo-saarka QAM ee internetka. Dhab ahaantii, maaha dhaqaale in loo rogo dhammaan TV-ga dayax-gacmeedka CATV haddii dayax-gacmeedka ugu weyn uu leeyahay waxyaabo badan oo TV caan ah. Way ka hufan tahay in la qaybiyo signalka dayax-gacmeedka oo ay weheliso CATV RF. Nidaamka FTTH oo aad iyo aad u badan ayaa geynaya GPON adeega internet-ka, caado dhaqameedka CATV ee gudbinta xawaaraha RF waxa lagu kordhin karaa 45 ~ 2150MHz, oo ay ku jiraan baahinta tayada sare leh ee CATV iyo Satellite TV. Iyada oo la adeegsanayo tignoolajiyada DWDM, injineerada Tiknoolajiyada Greatway waxay xalliyeen dhibaatadan gudbinta tooska ah ee RF ballaaran. GWT3500S waxay si gooni gooni ah ula macaamishaa CATV RF iyo satellite TV RF, iyadoo hubinaysa waxqabadka RF ugu wanaagsan ee kooxda CATV iyo band satellite siday u kala horreeyaan. GWT3500S waxay awood u siin kartaa FTTH MSO inay bixiso adeegyada TV-ga analoogga ah, DVB-C/T/S isla mar ahaantaana hal shabakad sida ugu fudud. Ka dib markii xaddi badan oo fiidiyowyo tayo sare leh lagu sii daayay daaqada indhaha ee 1550nm, adeegyada internetka ayaa leh xajmi badan oo waxtar leh. GWT3500S waxay la shaqayn kartaa GPON, XGPON, NGPON2 nidaamka FTTH. Waxay ku taal Shenzhen, Tiknoolajiyada Greatway waa RF ka badan guri naqshadeynta alaabada gudbinta fiber-ka iyo warshad tan iyo 2004, oo bixisa FTTH CATV qaataha, RFoG ONU ee modem fiilada ftth, satellite hal / Twin / Quatro LNB RF oo ka sarreeya GPON, Laba/Afar dayax-gacmeed oo ka sarreeya hal fiber isku xirka, 3224MHz Satellite Fiber Link, GPON iyo GPON+, EoC, 1218MHz CATV gudbiyaha indhaha iyo noodhka indhaha, baahinta heerka AV/ASI/SDI fiber link.
