GWT3500 1550nm CATV transmitter
Fa'amatalaga o oloa
GWT3500 o se faʻasalalauga tuusaʻo 1550nm DFB transmitter mo TV analog, TV numera ma CMTS faʻailoga faʻasalalau faʻapitonuʻu faʻapitonuʻu ma le QAM TV Faʻailoga mamao mamao felauaiga fiber.O lo'o fa'aogaina e le transmitter le laina maualuga DFB laser, RF power digital process technique, fa'atasi ai ma le RF pre-distortion circuit na atiae e Greatway Technology.O le microprocessor fausia i totonu e mataʻituina le tulaga galue transmitter ma otometi faʻamautinoa le faʻatinoga lelei.GWT3500 e lelei mo le tufatufaina alava TV analog i totonu ole 20Km ma le QAM TV faailoilo mamao mamao felauaiga i totonu ole 100Km.
Na faʻafeiloaʻi le Fiber e faʻasalalau le CATV RF i le 1990s ona o le maualalo o le faʻaogaina ma toetoe lava a le faʻatapulaʻaina bandwidth.RF i fiber converter o le meafaigaluega sili ona taua.Faatasi ai ma le maualalo o le leo leo ma le microprocessor, o le aofaʻi o le mana RF i luga o le laser e mafai ona faʻapipiʻi saʻo, faʻamautinoa le sili ona lelei o le faʻasologa o faʻasologa o mata (OMI).O le leisa DFB cooled i le transmitter fa'amautinoaina le tumau DWDM opitika umi galu mo fa'asalalauga po'o fa'aofiina narrowcasting feso'ota'iga auaunaga.I le taimi nei fa'amalieina leisa DFB e sili atu le laser RIN (feso'ota'iga malosi pisa) ma mautu leisa mana fa'aola.O le Ortel-Emcore maualuga laina fa'amalieina le DFB laser ma le Greatway design ua fa'amaonia e avea o se tu'ufa'atasiga manuia.GWT3500 optical transmitter ua faʻaaogaina lautele e tagata faʻatau i Amerika i Matu, Amerika i Saute ma Saina faʻatasi ai ma faʻatinoga sili ona lelei ma faʻamaonia lelei.
Faatasi ai ma le Greatway high power optical amplifier, GWT3500 transmitter e mafai ona tuʻuina atu faʻailoga TV maualuga maualuga i le fale poʻo le fiber i le fale.
isi vaega:
• Le pisapisao maualalo maualuga laina Ortel-Emcore cooled DWDM DFB laser.
• GaAs po'o GaN Tekinolosi e o'o atu i le 1218MHz.
• Fa'atekonolosi lelei a'o le'i fa'aseseina e fa'aleleia ai le CTB, CSO ma le C/N.
• Sa'o lelei le mata'itūina o le masini ma le vevela o lo'o iai le masini fa'apipi'i i totonu.
• Lelei mo CATV faʻasalalauga RF poʻo Narrowcasting RF i fiber.
• O le vaega pito i luma o le VFD o loʻo faʻaalia ai le tulaga ma le feʻau o galuega.
• SNMP pulega feso'ota'iga faitalia.
• 1310nm galu umi faitalia.
