Ingcaciso yeMveliso
Isishwankathelo seMveliso
I-receiver ye-CATV network optical receiver yamva nje yenkampani yethu ye-SR814ST, i-pre-amplifier isebenzisa i-GaAs MMIC epheleleyo, kwaye i-post-amplifier isebenzisa iimodyuli zeGaAs. Ngoyilo lwesekethe olulungisiweyo kunye namava obuchwephesha bokuyila iminyaka eli-10, esi sixhobo sifikelele kwizalathisi zokusebenza ezigqwesileyo. Ukongeza, ulawulo lwe-microprocessor kunye nomboniso we-digital parameter kwenza ukulungisa iingxaki zobunjineli kube lula kakhulu. Sisixhobo esiphambili esifunekayo ekwakheni inethiwekhi yeCATV.
Iimpawu zokusebenza
Isamkeli sethu se-CATV network optical esiphucukileyo i-SR814ST samkela ityhubhu yokuguqula i-PIN photoelectric conversion enempendulo ephezulu, siphucula uyilo lwesekethe kunye nemveliso yenkqubo ye-SMT, kwaye sifezekisa ukuhanjiswa kwemiqondiso ye-photoelectric okugudileyo nokufanelekileyo.
Iitships ze-RF attenuation ezizinikeleyo zibonelela ngokunciphisa okuchanekileyo okuthe ngqo, ngelixa izixhobo zethu ze-amplifier ze-GaAs zibonelela ngokunyusa okuphezulu kunye nokuphazamiseka okuphantsi. Inkqubo ilawulwa yi-microcomputer ene-chip enye (i-SCM), eneempawu zokubonisa ze-LCD, ukusebenza okulula nokubonakalayo, kunye nokusebenza okuzinzileyo.
Inkqubo ye-AGC iqinisekisa ukuba inqanaba lemveliso lihlala lingaguquki kuluhlu lwamandla okukhanya ukusuka kwi--9 ukuya kwi-+2 dBm kunye nokuphazamiseka okuncinci okuvela kwi-CTB kunye ne-CSO. Inkqubo ikwabandakanya ujongano lonxibelelwano lwedatha olugciniweyo, olunokudityaniswa nempendulo yolawulo lwenethiwekhi yohlobo lwesibini kwaye luqhagamshelwe kwinkqubo yolawulo lwenethiwekhi. Zonke iiparameter zobugcisa zilinganiswa ngokwe-GY/T 194-2003, phantsi kweemeko zovavanyo ezimiselweyo.
