GWT3500S CATV + SAT 1550nm Optical Transmitter
Fa'amatalaga o oloa
GWT3500S o se faʻaogaina saʻo 1550nm DFB leisa transmitter mo fiber mafiafia tufatufaina. GWT3500S o loʻo i ai le tasi fiber gaosiga ma lua faʻaoga RF: tasi mo le 45 ~ 806MHz 80ch analog CATV poʻo le DVB-C QAM poʻo le DVB-T ma le isi mo le 950 ~ 2150MHz Satellite Input. GWT3500S e mafai ona tuʻuina atu TV analog, DVB-C / T TV ma DVB-S / S2 satelite TV i luga o soʻo se faiga FTTH. Fa'atasi ai ma le fa'amalo o mata maualuga, GWT3500S e mafai ai e le FTTH MSO ona tu'uina atu le TV analog, DTT po'o le DVB-C, ma ola satelite vitiō mai na'o le tasi le transmitter opitika.
O le tele o fa'asalalauga TV RF i le CATV fa'auluuluga e mai i le lotoifale vitiō modulators, filifilia satelite vitiō toe-modulation ma initaneti QAM galuega. O le mea moni, e le o se mea tau tamaoaiga le liliu uma satelite TV i le CATV pe afai o le satelite autu o loʻo i ai le tele o mea taʻutaʻua TV. E sili atu ona lelei le tufatufaina o satelite faʻatasi ma CATV RF. Faatasi ai ma le tele ma sili atu FTTH faiga deploy GPON mo auaunaga i luga o le initaneti, o le CATV agai i luma RF bandwidth e mafai ona faalauteleina i le 45 ~ 2150MHz, e aofia ai le mauoa maualuga faasalalauga CATV ma Satellite TV. E ala i le DWDM tekinolosi, GWT3500S e feagai ma CATV RF ma satelite TV RF eseese, fa'amautinoa le lelei o le fa'atinoga o le RF i le fa'aili o le CATV ma le fa'aola satelite.
GWT3500S maua TV analog, DVB-C/T/S auaunaga i se auala faigofie. A maeʻa le tele o vitio maualuga o loʻo faʻasalalau i le 1550nm faʻamalama faʻamalama, o auaunaga i luga ole Initaneti e sili atu ona lelei le bandwidth. GWT3500S e mafai ona galulue ma GPON, XGPON, NGPON2 FTTH faiga.
isi vaega:
•Leisa maualalo maualuga linearity DFB laser.
•Tuto'atasi CATV RF fa'aoga ma Satellite RF fa'aoga.
•Lagolago e oo atu i le 32 transponders ile satelite 950~2150MHz RF.
•Lagolago i luga ole 80ch NTSC analog TV poʻo QAM ile 45~806MHz RF.
•O le vaega pito i luma o le VFD o loʻo faʻaalia ai le tulaga ma le feʻau o galuega.
