Ingcaciso yeMveliso
1. IsiShwankathelo seMveliso
SA1300CUthotho lwangaphandle lwe-bi-directional trunk amplifier sisixhobo esitsha sokukhulisa ingeniso ephezulu. Uyilo lwesekethe oluvuthiweyo kunye nolulungisiweyo, inkqubo yesayensi kunye nengqiqo yangaphakathi kunye nezixhobo eziphezulu, ziqinisekisa inzuzo ezinzileyo kunye nokuphazamiseka okuphantsi. Lolona khetho lulungileyo lokwakha uthungelwano lothumelo lweCATV olukhulu okanye oluphakathi.
2. Iimpawu zoMsebenzi
-Inqanaba elingaphambili indlela eyandulelayo ithatha esona salathisi siphezulu esingeniswe ngaphandle kwemodyuli yesandi sokutyhala-tsala okanye imodyuli yeGaAs yokutyhala, inqanaba lemveliso lithatha esona salathisi siphezulu samandla aphuma kumazwe angaphandle kabiniyImodyuli yeamplifier okanye imodyuli yeamplifier yeGaAs. Isalathisi esingenamgca silungile kwaye inqanaba lemveliso lizinzile. Indlela yokubuya ithatha eyona modyuli yeamplifier entsha entsha engeniswe kumazwe angaphandle. Ukuphazamiseka kuphantsi kwaye umlinganiselo wesignali kwingxolo uphezulu.
-Kukulungele ngakumbi ukulungisa ingxaki ngenxa yesihluzo se-plug-in ephindwe kabini, iplagi-in esisigxina (okanye ehlengahlengiswayo) isilinganisi kunye nesithinteli, kunye nenzululwazi kunye nengqiqo yokukhangela izibuko kwi-line.
- Isixhobo sinokusebenza ixesha elide ngokuqhubekayo ngokuthe ngcembe phantsi kwemeko embi yokusingqongileyo yangaphandle. Ngenxa yezindlu ze-aluminium ezingenamanzi, ukuthembeka okuphezulu kokutshintsha ukunikezelwa kwamandla kunye nenkqubo engqongqo yokukhusela umbane.
- Iqokobhe lamkela uyilo oluzinzisiweyo lwemodyuli; ukugcinwa kwezixhobo, ukutshintshwa, kunye nokulungiswa kweempazamo zilungile.
3. Isikhokelo sokuodola
Nceda uqinisekise: uplink kunye ne-downlink yokwahlula rhoqo iindlela ezimbini-directional.
4. Iingcebiso ezikhethekileyo:
- Ngaphambi kokusebenzisa imveliso kufuneka isiseko esithembekileyo!
- Ubuninzi bomthamo ogqithisiweyo wemveliso yi-10A.
