1. Takaitaccen Bayani game da Samfura

SR812S su ne masu karɓar gani na cibiyar sadarwar CATV ta duniya baki ɗaya tare da na'urar sarrafa hanyar sadarwa. Mai gabatarwa yana ɗaukar amplifier na GaAs MMIC kuma mai gabatarwa yana ɗaukar amplifier na GaAs mai ƙarfin lantarki sau biyu. Tsarin da'ira mai kyau, tare da ƙwarewar ƙirar RF ta ƙwararru ta shekaru, kayan aikin suna samun babban ma'auni. Tsarin tsari ne mai kyau ga cibiyar sadarwar CATV.

2. Siffa

- Bututun canza wutar lantarki mai ƙarfin PIN mai ƙarfi, ƙirar bandwidth 1G.
- Ragewa da daidaitawa na iya zama nau'in maɓalli mai daidaitawa akai-akaiko kuma nau'in sakawa. (Zaɓi ne)
- Fitar da wutar lantarki mai ninka biyu, babban riba da ƙarancin karkacewa.
- Ikon AGC na gani, lokacin da kewayon wutar lantarki ta gani ya kasance ⼍7～＋2dBm, matakin fitarwa ba zai canza ba.
- Mai canza hanyar sadarwa ta zaɓi, tallafawa tsarin gudanar da cibiyar sadarwa ta NMS.
