GWT3500 1550nm CATV transmitter
Ingcaciso yeMveliso
I-GWT3500 yi-modulation ethe ngqo ye-1550nm i-DFB transmitter ye-analog TV, i-TV yedijithali kunye ne-CMTS izibonakaliso zokusasazwa kwefiber dense kunye ne-QAM TV Signal yokuhanjiswa kwefayibha yomgama omde. Umthumeli usebenzisa i-laser ye-DFB ephezulu, amandla e-RF amandla edijithali inkqubo yenkqubo ezenzekelayo, kunye ne-RF yangaphambili yokugqwesa isekethe ephuhliswe yiGreatway Technology. I-microprocessor eyakhelwe-ngaphakathi ibeka iliso kwimo yokusebenza ye-transmitter kwaye iqinisekisa ngokuzenzekelayo ukusebenza okuthembayo. I-GWT3500 ilungele ukuhanjiswa kwefayibha ye-analog phakathi kwe-20Km kunye ne-QAM ye-TV ye-TV yokuhambisa umgama omde phakathi kwe-100Km.
I-Fiber yaziswa ukusasaza i-CATV RF ngo-1990 ngenxa yokuthotywa kwayo okuphantsi kunye ne-bandwidth engapheliyo. I-RF kwi-fiber converter sesona sixhobo sibalulekileyo. Ngesandisi-lizwi esisezantsi kunye ne-microprocessor, amandla e-RF ewonke kwi-laser anokusetwa ngokuchanekileyo, aqinisekise eyona ilungileyo i-optical modulation index (OMI). I-laser ye-DFB epholileyo kwi-transmitter iqinisekisa i-DWDM optical wavelength ezinzileyo yokusasaza okanye ifake iinkonzo ezisebenzisanayo ezinqamlekileyo. Ngeli xesha i-laser ye-DFB epholileyo ine-laser RIN engcono (ingxolo ye-relative intensity) kunye namandla azinzileyo e-laser. I-Ortel-Emcore umgca ophezulu opholileyo we-laser ye-DFB kunye noyilo lwe-Greatway lubonakaliswe ukuba luyindibaniselwano eyimpumelelo. I-GWT3500 i-optical transmitter isetyenziswe ngokubanzi ngabathengi kuMntla Melika, eMzantsi Melika nase China ngokusebenza okugqwesileyo kunye nokuthembeka okuqinisekisiweyo.
Kunye ne-Greatway high power optical amplifier, i-GWT3500 transmitter inokuhambisa umgangatho ophezulu we-TV yeempawu zefayibha kwisakhiwo okanye ifayibha ekhaya.
Ezinye iimpawu:
• Ingxolo ephantsi yomgca ophezulu we-Ortel-Emcore epholile i-DWDM DFB laser.
• I-GaAs okanye i-GaN Technology ukuya kuthi ga kwi-1218MHz.
• Ubuchwephesha obugqwesileyo bangaphambi kokugqwetha buphucula i-CTB, i-CSO kunye ne-C/N.
• I-microprocessor eyakhelwe-ngaphakathi ibeka esweni amandla emveliso ye-laser kunye nobushushu.
• Ilungele usasazo lweCATV iRF okanye iNarrowcasting RF kwifiber.
• Iphaneli engaphambili i-VFD ibonisa iiparamitha zemo kunye nomyalezo womsebenzi.
• Ulawulo lwenethiwekhi yeSNMP ngokuzithandela.
• 1310nm ubude bobude obukhethwayo.
