Ingcaciso yeMveliso

1. Isishwankathelo seMveliso

Ii-SR812S zizixhobo zethu zokwamkela i-CATV network optical receiver ezisebenzisa i-transponder yolawulo lwenethiwekhi. I-pre-amp isebenzisa i-all-GaAs MMIC amplifier kwaye i-post-amp isebenzisa i-GaAs power double amplifier module. Uyilo lwesekethe oluphuculweyo, kunye namava ethu obuchwephesha oyilo lwe-RF, izixhobo zifikelela kwi-index yokusebenza ephezulu. Yimodeli efanelekileyo yenethiwekhi ye-CATV.

2. Uphawu

- Ityhubhu yokuguqula i-PIN ene-photoelectric ephendula kakhulu, uyilo lwe-bandwidth ye-1G.
- Ukunciphisa kunye nokulinganisa kunokuba uhlobo lweqhosha oluhlengahlengiswayo ngokuqhubekayookanye faka uhlobo. (Uyazikhethela)
- Ukuphuma kwamandla kabini, inzuzo ephezulu kunye nokuphazamiseka okuphantsi.
- Ulawulo lwe-Optical AGC, xa uluhlu lwamandla okufaka i-optical luyi-－7～＋2dBm, inqanaba lemveliso alitshintshi.
- I-transponder yenethiwekhi ekhethiweyo, ixhasa inkqubo yolawulo lwenethiwekhi ye-NMS.
