1. Chidule cha mankhwala
SR812S ndipadziko lonse lapansi CATV network Optical receiver yokhala ndi network management transponder. Pre-amp imatengera zonse-GaAs MMIC kukulitsa ndipo positi-amp imatenga gawo lamphamvu la GaAs lokulitsa mowirikiza. Mapangidwe okhathamiritsa ozungulira, kuphatikiza ndi luso lathu lazaka zaukadaulo wa RF, zida zimakwaniritsa index yayikulu kwambiri. Ndi chitsanzo chabwino kwa maukonde CATV.
2. Mbali
- Kuyankha kwakukulu kwa PIN yosinthira zithunzi zamagetsi, kapangidwe ka bandwidth 1G.
- Attenuation ndi equalization akhoza mosalekeza chosinthika knob mtundukapena lowetsani mtundu.(Mwasankha)
- Mphamvu zochulukitsa kawiri, kupindula kwakukulu komanso kupotoza kochepa.
- Kuwongolera kwa Optical AGC, pomwe mphamvu yamagetsi yolowera ndi -7~+2dBm, mulingo wotuluka sunasinthe.
- Transponder yapaintaneti yosankha, thandizirani kasamalidwe ka netiweki ka NMS.
