Mafotokozedwe Akatundu
Chidule cha Zamalonda
Kampani yathu yaposachedwa kwambiri ya CATV network Optical receiver SR814ST yaposachedwa kwambiri, amplifier imagwiritsa ntchito ma GaAs MMIC athunthu, ndipo amplifier amagwiritsa ntchito ma module a GaAs. Ndi mapangidwe okonzedwa bwino a dera komanso zaka 10 za luso laukadaulo, chipangizocho chapeza zizindikiro zabwino kwambiri zogwirira ntchito. Kuphatikiza apo, kuwongolera kwa microprocessor ndi chiwonetsero chazithunzi za digito kumapangitsa kuti uinjiniya ukhale wosavuta kwambiri. Ndizida zazikulu zofunika pakumanga maukonde a CATV.
Makhalidwe Antchito
Makina athu apamwamba a CATV network optical receiver SR814ST amatengera chubu chosinthira chazithunzi cha PIN chokhala ndi mayankho apamwamba, chimakulitsa kamangidwe ka dera ndi kupanga njira za SMT, ndikuzindikira kutumiza kosalala komanso kothandiza kwa ma siginecha amagetsi.
Tchipisi zodzipatulira za RF zimapereka chiwopsezo chokhazikika, pomwe zida zathu za GaAs amplifier zimapereka phindu lalikulu komanso kupotoza kochepa. Dongosololi limayendetsedwa ndi single-chip microcomputer (SCM), yokhala ndi magawo owonetsera LCD, ntchito yosavuta komanso yodziwika bwino, komanso magwiridwe antchito okhazikika.
Dongosolo la AGC limawonetsetsa kuti mulingo wotulutsa umakhalabe wokhazikika pamitundu yamagetsi ya -9 mpaka +2 dBm ndikusokoneza kochepa kuchokera ku CTB ndi CSO. Dongosololi limaphatikizansopo mawonekedwe olumikizirana osungidwa a data, omwe amatha kulumikizidwa ndi mtundu wa II network management reaction ndikulumikizidwa ku network management system.Magawo onse aukadaulo amayezedwa molingana ndi GY/T 194-2003, pansi pamikhalidwe yoyeserera
