FAAHFAAHINTA Alaabada

Sharaxaada Alaabta

GWT3500S waa habayn toos ah 1550nm DFB laser gudbiyaha qaybinta cufan fiber. GWT3500S waxay leedahay hal wax soo saar fiber ah iyo laba wax-soo-saarka RF: mid loogu talagalay 45 ~ 806MHz 80ch analog CATV ama DVB-C QAM ama DVB-T iyo kan kale ee 950 ~ 2150MHz Satellite Input. 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, GWT3500S waxay si gooni gooni ah ula macaamishaa CATV RF iyo satellite TV RF, iyada oo hubinaysa waxqabadka RF ee ugu fiican ee kooxda CATV iyo band satellite siday u kala horreeyaan.

GWT3500S waxay bixisaa adeegyada TV-ga analoogga ah, DVB-C/T/S 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.
