GWR1000M CATV MiniNode

GWR1000M Optical MiniNode ili ndi doko limodzi la RF lokhala ndi ma analogi a TV, DVB-C ndi CMTS DS ma siginecha ndi ma siginecha a modemu okwera pamakina okhazikika kapena ophulika pamtundu umodzi wa Bi-directional fiber kapena ulusi umodzi. Ndi nyumba zotayidwa za aluminiyamu zakufa, GWR1000M ndi yabwino kwa ulusi wotsogola kupita kumalo (FTTP), CHIKWANGWANI mpaka pansi (FTTF) kapena ma fiber to the building (FTTB) application pa CATV and internet networks. GWR1000M node imapereka RF imodzi yotulutsa mpaka 1.2 GHz (1218MHz) yomwe imathandizira ma terminals ochepa a TV mwachindunji kapena kuyendetsa MDU amplifier mu network coaxial cable.

Node ya GWR1000M ndiyoyenera kugwiritsa ntchito kachulukidwe kwambiri: MDU, mayunivesite, zipatala ndi malo ochitira bizinesi. Ndi 20dBmV RF yotulutsa pa AGC mode, GWR1000M mininode imagwira kukhazikitsidwa kwazing'ono mosavuta. Ma transmitter obwerera amatha kukhala 1310nm kapena 1550nm pa 2^nddoko la fiber, kutengera zofunikira za dongosolo. Ukadaulo wa WDM wosankha umalola magwiridwe antchito anjira ziwiri pa chingwe chimodzi. CWDM kubwerera njira kuwala wavelengths alipo kuti kuphatikiza angapo njira ziwiri pa ulusi umodzi.

Monga njira yamkati yamkati, GWR1000M imatha kuyikidwa pakhoma ndi zomangira kapena patebulo. Yapanga chitetezo cha 6KV pamadoko onse a RF.

GWR1000M ili ndi doko limodzi loyesera -20dB, kuyang'anira njira yogwirira ntchito ndikubwerera njira ya RF.

GWR1000M itha kuyendetsedwa pa doko lodziyimira pawokha la RF ndi cholumikizira chakutali cha 15V DC, chomwe chimalola kutsika kwamagetsi a DC pamtunda wosakwana 30 mita RG6 chingwe kutalika. GWR1000M imathanso kuyendetsedwa pa doko la RF.
