1. Incamake y'ibicuruzwa

SR812S niyo receiver yacu ya CATV isanzwe ifite transponder yo gucunga umuyoboro. Pre-amp ikoresha amplifier ya GaAs MMIC yose naho post-amp ikoresha module ya GaAs power double amplifier. Igishushanyo mbonera cya serivise nziza, hamwe n'uburambe bwacu bw'imyaka myinshi mu gushushanya RF, ibikoresho bigira umusaruro mwiza. Ni icyitegererezo cyiza kuri reseri ya CATV.

2. Ikiranga

- Umuyoboro wa PIN uhindura amashanyarazi ukoresheje ikoranabuhanga rya 1G, imiterere y'umuyoboro wa bandwidth.
- Kugabanya no kuringaniza bishobora guhinduka mu buryo buhoraho mu bwoko bw'agapfundocyangwa shyiramo ubwoko. (Birakenewe)
- Ingufu zo gukuba kabiri, kwiyongera cyane no kugabanuka guke.
- Igenzura rya AGC y'urumuri, iyo intera y'ingufu z'urumuri rw'urumuri rwinjiye ari －7～＋2dBm, urwego rw'umusaruro nta gihindutse.
- Transponder y'umuyoboro idakenewe, ishyigikira sisitemu yo gucunga umuyoboro wa NMS.
