GWT3500 1550nm CATV transmitter
Product Description
GWT3500 ndeye yakananga modulation 1550nm DFB transmitter yeanalog TV, dhijitari TV uye CMTS inosaina yemunharaunda faibha dense kugovera uye QAM TV Signal kureba-kure faibha kutapurirana.Iyo transmitter inoshandisa yakakwira mutsara DFB laser, RF simba dhijitari otomatiki maitiro maitiro, pamwe neRF pre-distortion wedunhu rakagadzirwa neGreatway Technology.Iyo yakavakirwa-mukati microprocessor inotarisisa iyo transmitter yekushanda mamiriro uye otomatiki inova nechokwadi chekuita kwetarisiro.GWT3500 yakanakira analog TV faibha kugovera mukati me20Km uye QAM TV chiratidzo chedaro refu kutapurirana mukati me100Km.
Fiber yakaunzwa kufambisa CATV RF mu1990s nekuda kwekudzikira kwayo uye kunenge kusingagumi bandwidth.RF kune fiber converter ndiyo inonyanya kukosha midziyo.Iine yakaderera ruzha amplifier uye microprocessor, iyo yakazara RF simba palaser inogona kuiswa nemazvo, ive nechokwadi cheiyo optical modulation index (OMI).Iyo yakatonhodzwa DFB laser mune transmitter inovimbisa yakagadzikana DWDM optical wavelength yekutepfenyura kana kuisirwa narrowcasting inodyidzana masevhisi.Zvichakadaro yakatonhodzwa DFB laser ine nani laser RIN (relative intensity ruzha) uye yakagadzikana laser kubuda simba.Ortel-Emcore high linearity yakatonhodzwa DFB laser uye Greatway dhizaini yakaratidzwa kuve musanganiswa wakabudirira.GWT3500 optical transmitter yakashandiswa zvakanyanya nevatengi kuNorth America, South America neChina nekuita kwakanaka uye kwakaratidza kuvimbika.
Pamwe chete neGreatway high power optical amplifier, GWT3500 transmitter inogona kuendesa mhando yepamusoro yeTV masaini faibha kuchivakwa kana faibha kumba.
Zvimwe Zvimiro:
• Mutsindo wakaderera wepamusoro mutsara Ortel-Emcore wakatonhodzwa DWDM DFB laser.
• GaAs kana GaN Technology kusvika 1218MHz.
• Yakanakisa pre-distortion tekinoroji inovandudza CTB, CSO uye C/N.
• Yakavakwa-mukati microprocessor inonyatso tarisa laser kubuda simba uye tembiricha.
• Yakanakira CATV kutepfenyura RF kana Narrowcasting RF kuti faibha.
• Front panel VFD inoratidza mamiriro paramita uye basa meseji.
• SNMP network management sarudzo.
• 1310nm wavelength sarudzo.
