Tsananguro yeChigadzirwa
Pfupiso yeChigadzirwa
Kambani yedu yazvino ine CATV network optical receiver SR814ST, pre-amplifier inoshandisa GaAs MMIC yakazara, uye post-amplifier inoshandisa maGaAs modules. Nekugadzirwa kwedunhu kwakagadziridzwa uye makore gumi eruzivo rwekugadzira, mudziyo uyu wakawana zviratidzo zvekushanda zvakanaka. Pamusoro pezvo, microprocessor control uye digital parameter display zvinoita kuti kugadzirisa matambudziko einjiniya kuve nyore zvikuru. Ndiyo michina mikuru inodiwa pakuvaka network yeCATV.
Hunhu hweKushanda
Chigadziko chedu cheCATV network optical receiver chemhando yepamusoro SR814ST chinoshandisa chubhu yekushandura ine mhinduro yepamusoro yePIN, chinogadzirisa dhizaini yedunhu uye kugadzirwa kweSMT, uye chinoita kuti zviratidzo zve photoelectric zvitumirwe zvakanaka uye zvinobudirira.
Machipisi eRF attenuation akatsaurirwa anopa kuderedzwa kwakanyatsojeka kwemutsetse, nepo zvishandiso zvedu zveGaAs amplifier zvichipa kuwedzera kwakanyanya uye kukanganiswa kwakaderera. Sisitimu iyi inodzorwa necomputer ine chip imwe chete (SCM), ine maparameter ekuratidza eLCD, mashandiro ari nyore uye asinganzwisisike, uye mashandiro akagadzikana.
Sisitimu yeAGC inoita kuti huwandu hwezvinobuda hurambe hwakafanana pamusoro pesimba re optical kubva -9 kusvika +2 dBm pasina kukanganiswa kushoma kubva kuCTB neCSO. Sisitimu iyi inewo reserved data communication interface, iyo inogona kubatanidzwa kune type II network management responder uye yakabatana kune network management system. Ma technical parameter ese anoyerwa zvichienderana neGY/T 194-2003, pasi pemamiriro ekuyedza akajairwa.
