Incazelo Yomkhiqizo

1. Isifinyezo somkhiqizo

I-SR812S iyisitholi sethu esibonakalayo senethiwekhi ye-CATV esine-transponder yokuphatha inethiwekhi. I-pre-amp isebenzisa i-all-GaAs MMIC amplify futhi i-post-amp isebenzisa imojuli yokukhulisa amandla ephindwe kabili ye-GaAs. Idizayini yesekethe ethuthukisiwe, ehambisana neminyaka yethu yobungcweti be-RF design, okokusebenza kufinyelela inkomba yokusebenza okuphezulu. Kuyimodeli ekahle yenethiwekhi ye-CATV.

2. Isici

- I-PIN yokuphendula ephezulu yokuguqula isithombe sikagesi, idizayini yomkhawulokudonsa ongu-1G.
- Attenuation kanye Equalization kungaba ngokuqhubekayo adjustable knob uhlobonoma faka uhlobo.(Ongakukhetha)
- Ukukhipha amandla okuphindwe kabili, inzuzo ephezulu kanye nokuhlanekezela okuphansi.
- Ukulawulwa kwe-Optical AGC, lapho ububanzi bamandla okufakwayo kungu-－7～＋2dBm, ileveli yokukhiphayo empeleni ayishintshile.
- I-transponder yenethiwekhi yokuzikhethela, isekela uhlelo lokuphatha inethiwekhi ye-NMS.
