GWE1000 CATV MDU amplifier m'nyumba
Mafotokozedwe Akatundu
GWE1000 ndi amplifier yotsika mtengo yopangira nyumba zingapo yopangidwira njira yamasiku awiri yopita patsogolo CATV ndi Docsis 3.1 kapena Docsis 3.0 kapena Docsis 2.0 ma modemu a chingwe. Kupatula kuulutsa TV ya analogi yapamwamba kwambiri kapena DVB-C TV, GWE1000 imakwaniritsa zofunikira za maukonde olankhulirana amasiku ano omwe akukulirakulira kutengera CMTS ndiukadaulo wa modemu ya chingwe. Njira yakutsogolo RF ili ndi phindu la 37dB lothandizira mpaka 48dBmV RF kutulutsa pomwe njira yobwerera ili ndi phindu la 27dB lothandizira mpaka 44dBmV njira yobwerera ya RF. Zopangidwira kukhazikitsa netiweki ya HFC m'nyumba zogona, amplifier wopeza bwino kwambiri m'nyumbayi amapezeka ndi bandwidth mpaka 1003MHz (1218MHz mwina) kuti agwire bwino ntchito. Kupatula kugawanika koyambira kwa 42/54MHz, GWE1000 ikhoza kupereka 85/102MHz kapena 204/258MHz ma frequency ogawa pazofuna zapamwamba zamabandi.
Chokulitsa chowonjezera chimodzi chimakhala ndi chowongolera chosinthika mosalekeza komanso chofananira mosalekeza panjira zonse zakutsogolo ndi njira yobwerera ya RF kuti muzitha kusinthasintha kwambiri mukakhazikitsa amplifier. Chigawochi chimaphatikizapo madoko olowera amtundu wa F ndi zolumikizira zotulutsa, -20dB njira yakutsogolo ndi -20dB madoko oyesa njira yobwerera. Kuti mukwaniritse ntchito zosiyanasiyana m'mapulogalamu okhala mulit, madoko onse a RF a GWE1000 adapangidwa kuti azikhala ndi chitetezo cha 6KV.
GWE1000 imagwiritsa ntchito mphamvu zosakwana 14W. Ma module onse amplifier amayikidwa pa sinki imodzi yotentha ya aluminiyamu. GWE1000 ili ndi chivundikiro chanyumba chachitsulo chokhala ndi zosindikiza za silika.
MDU imakhala ndi magetsi osinthika okha, omwe amatha kuvomereza ma voltages olowera kuchokera pa 90 mpaka 240V pama frequency a 50 kapena 60 Hz popanda kusintha.
Zina:
• Duplexer yogawa ma bandwidth osiyanasiyana.
• 90 ~ 240V AC mphamvu zolowetsa.
• -20dB mayeso olowera kutsogolo ndi njira yobwerera.
